Nimham Mountian Loop

Starting from the Coles Mills Trailhead off Coles Mills Road, this route heads north on a wide path through hardwood forest toward the summit of Mount Nimham. After a steady but manageable climb, the trail reaches the historic Mount Nimham fire tower, a restored 1930s structure offering panoramic views over the Hudson Highlands and surrounding forests. From the tower, continue south down Tower Road until you reach a signed junction with the Blue Trail—turn right here. The Blue Trail winds through quiet woods, heading south and then bending northeast as it traverses rolling terrain. At the next signed intersection, connect to the Yellow Trail, which leads you southwest to the lower section of the Mount Nimham Loop. Follow this final stretch back to the trailhead to complete the route. This moderate hike offers a peaceful experience with classic features of day hikes in the Hudson Valley—mixed forest, wildlife, and a rewarding view from a high elevation point.
