From steep hills to old fields to quiet wetlands, this 20-mile National Recreation Trail offers surprising diversity. From Cold Spring Harbor, where mountain laurels bloom in June, the trail crosses Long Island to Massapequa Preserve watershed, where dozens of species of birds stop on their fall and spring migrations. Paths for mountain bikers parallel parts of this trail, and a loop in the Plainview area provides a connection with the Walt Whitman Trail.

Well maintained and peaceful

Hiked Sept 1 and 2, 2026. This is a well-maintained and well-blazed trail. Terrain in the northern miles is quite hilly, but the trail flattens out as one hikes south. You’re mostly in the woods, but there are minor sections of bike path walking. Other trails intersect this one as you move through the state parks, so be sure to follow the white blazes. This is truly an enjoyable long stretch of greenery in the midst of one of the most populated places in the country. Mileage may be closer to 19 or 20 depending on which map or activity tracking app you use.
