Harriman State Park
A vast, wooded escape with lake walks, ridge routes, and changing trail difficulty.
Artwork inspired by Ernest Lawson
Harriman State Park spreads across the wooded ridges of Rockland and Orange counties, with 31 lakes and reservoirs and roughly 200 miles of hiking trails. This is not a single compact park: a lakeside picnic, a beach day, and a rocky ridge hike start at different access points.
Choose a named lake or trailhead before driving, carry an offline trail map, and check the park's notices for weather and beach status. Lake Tiorati and Lake Welch have seasonal swimming areas; swimming elsewhere is not automatically allowed. The park opens from dawn to dusk all year. Only select lots collect a summer vehicle fee, so the charge depends on where and when you enter.

Know before you go
- Choose the trailhead
- Match your route to distance and terrain, not just the park name.
- Pause beside a lake
- Notice how forest, roads, and water share the preserve.
- Stay on marked paths
- Rocky junctions are easy to misread without a map.
- Check swimming rules
- Use designated, staffed areas only when open.

The map pin marks the main park listing, not every trailhead or swimming beach.
