Iceland's Laugavegur, the Kungsleden, Alta Via 1, the West Highland Way and the Tour du Mont Blanc: what each one asks of you over three days, and what has to be booked before you go.
A three-day fastpack is the cheapest big trip I know of. You leave on a Friday, sleep out twice, and get home Sunday night having covered ground that would take most of a week under a full pack. Europe is unusually good at this for one reason: somebody already built the infrastructure.
In the Dolomites and around Mont Blanc that infrastructure is a staffed hut with a cooked dinner waiting. In Swedish Lapland it's a touring-club cabin, plus a legal right to pitch a tent nearly anywhere sensible. Scotland just has a village every few hours. All three do the same job: they lift the shelter, the quilt, the stove and most of the food out of your pack, and what's left fits in something you can run in.
The five below are ordered by the size of the days they ask for, gentlest first. I'm counting three days as three moving days and two nights out. None of them requires you to run all of it. All of them require something arranged before you fly: a bed, a permit, or at minimum a look at the season.
The shortlist
Five fastpacking routes that fit in three days
Distances and elevation figures here come from each route's own land manager or operator. The daily averages are just the total divided by three. Crude, but it's the fastest way to see whether a route is your size before you commit to it.

Laugavegur and Fimmvörðuháls
Icelandic highlands — Landmannalaugar to Skógar
Distance
About 80 km — 55 km Laugavegur plus 25 km Fimmvörðuháls
Averages out at
Roughly 27 km a day
Season
Around 25 June to 15 September, per Ferðafélag Íslands
Nights
Ferðafélag Íslands huts and campsites — booking expected
High point
The 1,000 m Fimmvörðuháls pass
The Laugavegur runs 55 km from the hot springs at Landmannalaugar to the birch woods of Þórsmörk. Ferðafélag Íslands, the Icelandic Touring Association that runs the huts, breaks it into four legs of 12, 12, 16 and 15 km. Bolt the 25 km Fimmvörðuháls crossing onto the end, over the pass between two ice caps and down to Skógafoss, and a comfortable four-day walk becomes a three-day fastpack that finishes with a real mountain day.
It's the gentlest entry on this list because the daily distances are small and the huts sit close enough together that you can bail or stop early without wrecking the plan. What it asks for instead is tolerance. Ferðafélag Íslands puts summer days at 5 to 14°C and nights at 0 to 10°C, says rain is common and that fog is common on the first two segments, and notes that at least three rivers have to be waded.
Booking is not optional here. The association's own guidance is that walkers are expected to have confirmed bookings for huts or campsites before they start, and its huts are small.
Why it's here: The daily distances are the smallest here, and the weather is the least predictable. Plan for cold rain and rivers, and the mileage takes care of itself.

Kungsleden, Abisko to Nikkaluokta
Swedish Lapland — the northern stage of the King's Trail
Distance
107 km, per the Swedish Tourist Association
Averages out at
Roughly 36 km a day
Normally takes
Seven stages; STF says it can be done in five days
Season
Cabins open roughly mid-June to mid-September
Nights
STF mountain cabins, or your own tent under the right of public access
The Kungsleden runs about 450 km in total, and its northern stage is the piece I'd fly for. The Swedish Tourist Association (STF) puts Abisko to Nikkaluokta at 107 km across seven stages of 15, 21, 13, 12, 12, 15 and 19 km, and says it can be completed in five days at walking pace. Compress that to three and you get three days of about 36 km through open, gently graded tundra valleys. That's a very different day from 36 km in the Alps.
It's also the one route here with two independent ways to sleep. STF's cabins are self-catering, spaced 10 to 20 km apart, and the association's own booking guidance is unusually forgiving: book ahead and you get a cheaper bed guaranteed if you arrive by 18:00, and if you haven't booked you'll still be offered a place, paid on site. Separately, Sweden's right of public access, allemansrätten, lets you pitch a tent for a night or two on unenclosed land as long as you keep well away from houses.
Read the exception before you rely on it: the Swedish Environmental Protection Agency says that inside national parks and nature reserves tents are generally allowed only at designated sites, and the whole first stage runs through Abisko National Park, where camping is confined to three spots — the tourist station, Nissonjåhka five km in, and the Abiskojaure cabins.
Carrying a tent you may not use costs you a kilo. Take it anyway. Once you're south of the park boundary, a kilo is a cheap price for being able to stop where you are when the weather closes in.
Why it's here: You could decide to do this one three weeks out. Nothing on the route has to be reserved ahead, and once you're clear of the national park a full cabin just means pitching the tent instead.

Alta Via 1
Dolomites, Italy — Lago di Braies to Belluno
Distance
125 km across 12 stages
Ascent
Over 7,300 m up, over 8,400 m down
Averages out at
Roughly 42 km and 2,400 m of climbing a day
Season
Late June to late September, while the rifugi are open
Grade
E to EEA — the harder sections need via ferrata gear
Parco Nazionale Dolomiti Bellunesi gives the Alta Via 1 as 12 stages, 125 km, over 7,300 m of ascent and over 8,400 m of descent, running north to south from Lago di Braies down to Belluno. Squeezing twelve stages into three is the biggest compression on this list, and the vertical is the part you'll feel: 2,400 m of climbing a day, on limestone, at altitude.
The huts are what make it possible at all. The regional tourist board counts 15 rifugi on the main route plus a bivouac and six refreshment points, so you're rarely more than a couple of hours from a hot meal and a bunk. Carry a liner and a wind shell and you can run this in a vest.
The decision to make before you leave home is the grade. The route is rated E to EEA, and EEA means sections equipped with cables where you're expected to have a via ferrata kit: harness, lanyard and helmet, about a kilo you'd otherwise never carry on a fastpack. That ground is concentrated at the southern end: the park grades its last two stages EEA, and the one stage the regional board flags for cables, the eleventh, has a marked variant that avoids them.
Where you finish, and which line you take on that stage, is what decides your pack list.
Why it's here: The hardest climbing of the five, and the one route where the grade matters more than the distance. Decide how far south you're finishing before you touch the pack list.

West Highland Way
Scotland — Milngavie to Fort William
Distance
96 miles (154 km), per the official route
Averages out at
Roughly 51 km a day
Normally takes
Eight official sections; six to seven days on average
Season
Walkable most of the year; the midges peak in high summer
Nights
Villages, hostels and campsites — plus camping byelaws on Loch Lomond
The official route puts the West Highland Way at 96 miles (154 km) from Milngavie on the edge of Glasgow to Fort William, split into eight sections of between 9 and 15 miles. Three days means covering nearly three sections a day. That's the longest daily distance on this list, and the only reason it's realistic is that this is also the flattest and best-surfaced route of the five.
Nothing here needs booking in the alpine sense. You pass through villages with shops, pubs and beds, so you can carry a day's food at a time and no shelter at all. The catch is the one piece of paperwork on the route: Loch Lomond & The Trossachs National Park runs camping management byelaws between March and September, and inside the Camping Management Zones you may only camp at a campsite or with a permit.
Permits are £4.30 per tent per night, the zones cover less than 4% of the park, and camping in one without a permit can end in a report to the Procurator Fiscal and a fine of up to £500. The park drew the zones around its lochshores, and the Way runs along the east shore of Loch Lomond from Balmaha to Inverarnan — its second and third official sections.
Book a bed and the byelaws stop mattering. Plan to camp wild along Loch Lomond and they matter a lot, so look at the zone map before you decide which kind of trip this is.
Why it's here: Shops and beds instead of huts, and the easiest travel of the five. You pay for it in miles.

Tour du Mont Blanc
France, Italy and Switzerland — the full circuit
Distance
170 km, per the official route
Ascent
10,000 m
Averages out at
Roughly 57 km and 3,300 m of climbing a day
Normally takes
About ten days; anti-clockwise is the classic direction
Countries
France, Italy and Switzerland
The official Tour du Mont Blanc figures are 170 km and 10,000 m of ascent over roughly ten days across three countries, walked in either direction but classically anti-clockwise. Three days means three consecutive days of 57 km and 3,300 m of climbing, and I want to be plain about what that is: the hard end of this list by a wide margin, and more than most fit fastpackers should sign up for on a first European trip.
Four to six days is the version I'd recommend to anybody going for the first time.
It's on the list anyway. It's the trip the other four prepare you for, and refuges and gîtes run the whole way around with half board, so the pack stays small even on the biggest days.
The paperwork is the part people underestimate. Alpine refuges take reservations that hold you to them. Under the Swiss Alpine Club's terms a booking becomes binding for both sides as soon as it's confirmed, you can cancel free only until 18:00 two days before, and a no-show can be charged up to the full value of what you reserved.
Three countries works out to two currencies — euros in France and Italy, Swiss francs in between — and a passport or ID card in the pack, since you're crossing national borders on foot.
Why it's here: Save this one for later. Do one of the shorter four first, find out what you can eat and drink on a 35 km day, then come back.
What holds you up, and what it takes out of the pack
Pick your support system before you pick your gear. Four of them cover the five routes above, in different combinations, and each one takes something different off your back.
What holds you up
On this list
What it takes out of the pack
What you have to arrange
Staffed hut with half board
Alta Via 1, Tour du Mont Blanc
Shelter, quilt, stove, and most of the food
Book early. A confirmed alpine reservation is binding, with a cancellation deadline days ahead
Warden's hut where you cook
Laugavegur, Kungsleden
Shelter and quilt, but you still carry the food
Iceland expects a confirmed booking before you start; Sweden will find you a space indoors
A legal right to camp
Kungsleden
Nothing — but it removes the booking entirely
Nothing to book. Inside a national park, though, tents only at the marked sites
Villages and shops on the route
West Highland Way
Shelter, quilt, and nearly all the food
Beds in summer, or a camping permit inside the byelaw zones
The Kungsleden appears twice on purpose. A cabin network and a right to camp are two separate fallbacks, and no other route here has both.
What actually goes in a pack that small
Assume a hut or a village every night. Once the shelter, the sleeping bag and most of the food are somebody else's problem, what's left is short. It also includes a few European-specific items that trip up first-timers.
The hut kit nobody tells you about
A sleeping bag linerNot optional in Italy. Club Alpino Italiano rules say you must use a sacco-lenzuolo in a rifugio, and to ask the warden for one if you turn up without.
EarplugsA shared dormitory, and people getting up at 4 a.m.
Cash, in the right currencyCard acceptance at altitude is patchy, and it differs from hut to hut. The Tour du Mont Blanc alone spans euros and Swiss francs.

Gear that decides whether the pack fits
Three days out of a hut is a genuinely small kit list, which means the pack, the shoes and the poles are doing nearly all the work. These are the guides we've written on those.
The running is the easy part to plan. This is the order to do everything else in, because getting it backwards is how people end up with flights and no beds.
01
Pick the route to match your current long day, not your best one
Take your honest longest day of the last six months and ask whether you'd want to repeat it twice more, back to back, on tired legs. That's what the averages in the list above are for. If 36 km in Lapland already sounds like a stretch, then 57 km a day around Mont Blanc is how people get hurt.
02
Check the season before you look at flights
Every route here has a window set by somebody else. Ferðafélag Íslands puts the Laugavegur at roughly 25 June to 15 September. STF's Kungsleden cabins run from about mid-June to mid-September — 18 June to 13 September in 2026. The Dolomites rifugi are late June to late September. Book travel outside those windows and the huts you were counting on are closed.
Shoulder-season dates move with the snow every year. Treat the published window as approximate and check the operator's page for the current season.
03
Book the beds, then the travel
Beds are scarcer than airline seats. Ferðafélag Íslands says its huts sell out quickly in peak season, popular alpine huts go the same way, and a three-day plan has no slack to absorb one full hut. Get the nights confirmed first and buy the flights around them.
04
Read each hut's own rules, one at a time
They differ, even within one country. What half board includes, whether a liner is required or rented, what time dinner is served, whether cards work, what time you have to arrive by: all of it is set per hut, and all of it is on that hut's own page.
05
Write down every cancellation deadline
Write them in your calendar as you book, one line per hut. Under the Swiss Alpine Club's terms a reservation is binding as soon as it's confirmed, free cancellation ends at 18:00 two days before your stay, and a no-show can be billed up to the full value of what you booked.
The SAC does waive the no-show charge if you can document that severe weather made the route impossible and you tell them by 18:00 the day before.
06
Leave a plan with someone who isn't on the trip
A three-day route with a small pack has very little margin, and two of these five are genuinely remote. Iceland's SafeTravel service asks walkers to leave a travel plan and to tell somebody trustworthy, then update them if the plan changes. Worth doing on all five.
The words you'll meet on the booking pages
Refuge, rifugio, hütte, cabane, fjällstuga
The mountain hut, in French, Italian, German, Swiss French and Swedish. Staffing and comfort vary enormously: some serve a three-course dinner, others are a self-catering cabin with bunks and a stove.
Half board (demi-pension, mezza pensione)
Dinner, a bed and breakfast, bought as one thing. What dinner actually is gets set per hut and is on that hut's own price list. Drinks are not in it: the Club Alpino Italiano prices meals with beverages excluded, so water and wine land on the bill separately.
Sleeping bag liner (sacco lenzuolo, Hüttenschlafsack)
A thin sack that keeps you off the hut's shared blankets. Required to sleep in an Italian rifugio, and expected across most of the Alps. It weighs almost nothing.
Dormitory (dortoir, matratzenlager)
The shared sleeping room, often a long platform of mattresses side by side rather than separate beds. This is what you've booked unless you paid for a private room.
Allemansrätten
Sweden's right of public access. It lets you walk across and pitch a tent on unenclosed land for a night or two, well away from homes, provided you damage nothing. Inside national parks and nature reserves it is restricted, and tents are generally allowed only at designated sites.
Col, passo, joch, forcella
The pass, meaning the low point on a ridge where a route crosses it. On these routes it's usually the day's high point as well, and the coldest, snowiest ground you'll cross.
EEA
The Italian grade for a route with cable-protected sections, meaning you're expected to carry a via ferrata kit: harness, energy-absorbing lanyard and helmet. Alta Via 1 is graded E to EEA.
Your loaded pack minus everything you'll consume, so no food, water or fuel. Every gear list quotes it because it's the one number that doesn't change while you walk.
Common questions
Is three days really enough for these routes?
For four of the five, comfortably, as long as you're honest about the daily distance. The Laugavegur with Fimmvörðuháls attached averages about 27 km a day, the Kungsleden's northern stage about 36 km. Long days, but nothing exotic. The Tour du Mont Blanc is the outlier: 57 km and 3,300 m of climbing a day, three days running, is a serious undertaking, and most people should give it four to six.
Do I need to be able to run the whole thing?
No, and almost nobody does. Fastpacking in practice means hiking the climbs, jogging the flats and running the descents, which is how ordinary people cover 35 or 40 km in a day. Fitness still matters. If you can't already cover the distance without a pack, a lighter pack won't fix that.
Can I skip the huts and camp instead?
It depends entirely on the country, and this is the biggest difference between fastpacking in Europe and in the US. Sweden's right of public access lets you pitch a tent for a night or two on unenclosed land away from homes, but not inside a national park, where tents are generally confined to designated sites — and the Kungsleden starts inside one. Iceland's Laugavegur operator expects a confirmed booking for a hut or a campsite before you start.
In Scotland's Loch Lomond & The Trossachs National Park, camping inside the management zones between March and September needs a permit or a campsite. Check the specific route rather than generalizing from one of them.
How light does my pack need to be?
Light enough to run in, which in practice means a 20 to 35 liter vest-style pack rather than a target weight. Sleeping in huts does most of the work for you: no tent, no sleeping bag, no stove, and only the food between one hut and the next. It's also the reason a first fastpack is easier here than at home.
Do I need a via ferrata kit on Alta Via 1?
It depends on how far south you go. The route is graded E to EEA, and EEA sections are equipped with cables where a harness, lanyard and helmet are expected. Those sections sit toward the Belluno end, and the one stage flagged for cables has a marked variant around them, so your finish point and your line on that stage decide whether you're carrying roughly a kilo of climbing gear. Settle that before you pack.
Which one should I do first?
The Kungsleden's Abisko to Nikkaluokta stage, if you want the widest safety net: STF says walk-ins without a booking are still given a place indoors, the right of public access means a tent is a legal fallback once you're out of the national park, and the gradients are gentle. The Laugavegur is the better pick if you'd rather have shorter days and more dramatic ground, and you can commit to booking months ahead.
