Top 10 one-day hikes within an hour of Manhattan

New York State Parks describes this one as a linear park running over 26.2 miles of the original 41-mile aqueduct, from Van Cortlandt Park at the Bronx and Yonkers line north to the Croton Dam. It was built to carry drinking water to the city, it's a National Historic Landmark, and the path on top of it is the flattest long walk anywhere near New York.

What makes it a hiking route rather than a curiosity is the Hudson Line. The railroad runs alongside it for most of its length, so you can get off a train at one station, walk north through several villages under old trees, and get on another train wherever you've had enough. Yonkers to Irvington is the obvious first go: 34 minutes out from Grand Central, 49 minutes back, and no decision to make about how far you feel like walking until you're already walking.

The state's note that the trail has no parking areas of its own tells you what kind of path this is: one built around the towns it passes through rather than around a lot. That's why it's the most reliable Saturday on this list, because there's no lot to fill. It's open sunrise to sunset, year round, and it costs nothing.

This is the strongest car-free hike on the list and the one that surprises people most. NJ Transit runs the Morris & Essex line to Millburn hourly on a Saturday, and its published schedule data puts the run from New York Penn Station at about 45 minutes. From the platform, the reservation's Locust Grove entrance is a few minutes' walk — that is our own measurement off the map rather than a figure any agency publishes.

Behind it are 2,112 acres of hardwood and hemlock between the first and second Watchung ridges, with the west branch of the Rahway River running down the middle. Essex County's own page gives the acreage as 2,112 in one line and 2,110 in the next, which tells you roughly how precisely anyone has measured it.

Frederick Law Olmsted walked the newly bought land before handing the design to his stepson's firm, and Essex County says he regarded it as some of the most beautiful and promising terrain he had ever seen. The Olmsted Brothers finalized the layout in stages, and the Civilian Conservation Corps built the trails, footbridges and shelters in the 1930s. Hemlock Falls, a 25-foot drop deep in the woods, is the destination most people walk to.

The better one is Washington Rock, on the eastern ridge 550 feet above Millburn. Essex County calls it the park system's bona fide Revolutionary War historic site: Beacon Signal Station 9 stood here, one of 23 beacons built by General Washington to watch British troop movements on Staten Island and in New York City. On 23 June 1780 it was from this outlook that the Essex County and Newark militia were first warned of a British attack westward toward Hobart Gap.

You're standing on a lookout built to watch the city, an hour after leaving it.

The reservation carries a segment of the Lenape Trail, a 36-mile urban and suburban route connecting 18 parks and 11 municipalities across Essex County, mapped by the Trail Conference with the county. One thing to settle before you go: the Locust Grove parking lot and the Rahway Fairy Trail are shut for a $1.2 million improvement project, funded by a Green Acres grant and the county's open space trust fund, and the South Mountain Conservancy has been pushing the end date back as rain slows the work.

Arriving by train sidesteps the lot, but not the trail closure, and the Lenape Trail is on a detour through there flagged with yellow ribbon. The Conservancy says the South Orange lot near Hemlock Falls is open, and it posts the current dates.

Eagle Rock is the view. Essex County's reservation sits on the crest of the Watchungs' First Mountain, 408 acres of it between West Orange, Montclair and Verona, and from Lookout Point, at the main entrance on Eagle Rock Avenue, you get the whole of the thing you drove out of: the suburbs first, then Newark, then the Manhattan skyline lying along the horizon. The county's brochure puts the sweep at everything between the George Washington Bridge and the Verrazzano.

It describes the reservation itself as primarily undeveloped, predominantly red oak, and laced with bridle paths and hiking trails, which is accurate about the woods and undersells the overlook. The mountain got its name early in the nineteenth century, when bald eagles were said to nest in the rocky cliffs on the eastern edge.

People have been coming out from the city to do exactly this for a very long time. Essex County bought the first piece of the reservation in 1895, finished assembling the tract in 1907, and had Frederick Law Olmsted draw a preliminary design that his firm developed in the early 1900s.

The trolley got here first: a line to the foot of Eagle Rock Avenue opened in 1894, and the county's own history is candid about how it worked, saying the promoters knew the grade was too steep to carry anyone to the top and simply counted on their passengers climbing the last hundred feet up a zigzag path cut into the side of the cliff.

The Lenape Trail, yellow blazes, runs 1.83 miles inside the park on the county's own key and carries on well beyond it, which is what turns a short visit into a longer day.

Two things to know before you go. The overlook is also the Essex County September 11th Memorial, dedicated in October 2002 on the hilltop where, as the county puts it, thousands made their way to watch the events unfolding at the World Trade Center, and where cards, candles, flags and flowers filled the wall overlooking New York in the days afterwards. A 7,400-pound piece of the World Trade Center foundation was installed there in 2011.

The county calls it a place to find comfort and solace, and the memorial and the overlook are the same spot, which is worth knowing before you turn up with a picnic. The other thing is that this is the least walking on the list: the county's five marked trails add up to just over seven miles between them, none of them rated above moderate, so it is an afternoon rather than a full day unless you pick up the Lenape Trail and keep going.

Nyack Beach is 61 acres of riverfront, and from its parking lot a flat gravel path, the Nyack River Trail, runs 1.6 miles north along the water beneath the cliffs. That on its own is an easy, entirely level walk. The reason to come is the other option: the Switchback Trail climbs 0.24 miles from the shore up to the Long Path, which runs 5.8 miles through Nyack Beach and Rockland Lake and goes straight over the top of Hook Mountain.

From up there the river spreads out wide below you and you can see down the length of the Tappan Zee. It's the best big view within thirty road miles of Manhattan, and the climb to reach it is short and steep rather than long. Every one of those distances comes off the trail features key on New York State Parks' own map for the two parks, produced by its GIS bureau and dated August 2023.

The rules here are unusually specific, and they're printed on the same map: no drones, no swimming in the lake or the river, no open fires, no tents or camping, no hunting, and nothing tied to trees, hammocks included. The park is open dawn to dusk for day use all year. The vehicle fee is seasonal, and the state posts the year's collection dates on the park's page rather than fixing them once; outside them, parking is free.

This is the most mountainous ground within thirty road miles of Manhattan. The New Jersey State Park Service calls Ramapo Lake the central feature of the area and says it has spectacular views from numerous rock outcroppings and ledges, and describes the trails as meandering old roads, historic trails, and more challenging rock scrambles. The rock here is real rock: bare, glacially scoured ridges with genuine drop-offs and long views east over the Wanaque valley.

The state's trail brochure gives the shape of the day. It counts 14 official trails totalling more than 28 miles, and the two that matter here both start from Skyline Drive: the 0.6-mile Ramapo Lake Spur Trail runs from the lower parking area to the blue-blazed Ramapo Lake Loop Trail, which follows a lakeside fire road 2.6 miles around the water.

The white-blazed Castle Loop Trail is the 3.1-mile version, dropping to the lake and then climbing to viewpoints by the ruins of Van Slyke Castle, a stone mansion built in 1910 and abandoned in 1940. There is no vehicle access to the lake at all; the state's measure of that is that boats have to be carried in about 1.2 miles.

Two things to plan around. Hunting is permitted in specific sections of the forest and the state publishes a map of them, so late autumn wants blaze orange and a look at the dates. And there are no trash cans anywhere: as the state puts it, whatever you carry into the park, plan on carrying it out too.
