We offer guided hikes as part of our popular Take-a-Hike! series during the spring through autumn months. Hikes showcase HHLT’s nature preserve, Granite Mountain Preserve, located in the heart of Putnam Valley. Each unique hike aims to get people outdoors and connect with the natural beauty of the Hudson Highlands.

Take-a-Hikes! are always FREE and OPEN TO ALL, but advanced registration at is required for all hikes and volunteer days. Please email Ashley Rauch to RSVP for any hikes.


Please note all guided hikes scheduled before the end of May have been cancelled or postponed in accordance with current CDC and New York State recommendations.
