Climb to the top of the fire tower to get great panoramic views of the surrounding hills, including Stockholm Hill and the Little and Big Buck mountains. This is a great spot!

Incredibly steep dirt road leads to the top but the views from the top of the tower are well worth it.

Yes, the region offers several accessible trails perfect for families. The hike to the Ninham Mountain Fire Tower is a great option; it's a relatively easy 1.5-mile round trip on a gravel road, suitable for many abilities. Another excellent choice is the Putnam Trailway, a 12-mile paved path that provides a flat and scenic route for walking or biking.
For panoramic views, the top of the fire tower at Ninham Mountain is unmatched, offering 360-degree vistas of the Hudson Valley. For a more challenging climb with a rewarding view, the Fahnestock Trail to Round Hill in Clarence Fahnestock Memorial State Park provides expansive, west-facing views that can reach the Hudson River on clear days.
Most state parks and multiple-use areas in the Mahopac region, including Clarence Fahnestock Memorial State Park and Ninham Mountain Multiple Use Area, are dog-friendly. However, pets must be kept on a leash, typically no longer than 6 feet, and you are expected to clean up after them. Always check the specific park's regulations before you go.
Several parks and preserves in the area are highly regarded by local hikers.
Clarence Fahnestock Memorial State Park is a vast park with over 50 miles of trails catering to all skill levels. Ninham Mountain Multiple Use Area is a popular favorite, known for its accessible fire tower and extensive trail network. For a different experience, Croton Gorge Park, set at the base of the Croton Dam, offers scenic walks and is a top-rated local spot.
Yes, a significant section of the Appalachian Trail (A.T.) runs through Clarence Fahnestock Memorial State Park. You can experience this iconic trail on routes like the Canopus Lake via Appalachian Trail loop, which incorporates a portion of the A.T. as it passes through the park's scenic woodlands.
The Hudson Highlands terrain provides plenty of challenges. In Clarence Fahnestock Memorial State Park, the Catfish Loop Trail is a moderately challenging 4.9-mile hike with varied terrain and stream crossings. For a steep climb, the trail to the summit of Round Hill within the same park offers a strenuous but rewarding workout.
The trails around Mahopac are well-regarded by the komoot community. Hikers often praise the region's natural beauty, particularly the combination of dense woodlands and serene lakes. The well-maintained trails in parks like Fahnestock and the rewarding views from summits like Ninham Mountain are frequently mentioned as highlights.
Yes, loop trails are very common. The Three Lakes loop is a popular 7.5-mile circular route in Clarence Fahnestock Memorial State Park. For an easier option, the Mount Nimham Loop is a 3.7-mile trail that circles the mountain.
The terrain is typical of the Hudson Highlands, characterized by rolling, rocky hills and deep forests. Trails in Clarence Fahnestock Memorial State Park often feature rocky ridges, stream crossings, and sections of exposed bedrock. In contrast, the Putnam Trailway offers a completely different experience with a flat, paved surface.
Winter hiking is a great activity in Mahopac, but be sure to wear appropriate footwear with good traction, like microspikes. For other winter sports, Fahnestock Winter Park offers machine-groomed trails for cross-country skiing and snowshoeing when conditions permit.
Clarence Fahnestock Memorial State Park has multiple parking areas depending on which trail you want to access. For trails around Canopus Lake, there is a large beach parking lot (a vehicle use fee may apply in season). Other trailheads, such as those for the Appalachian Trail or Charcoal Burners Trail, have smaller designated lots along Route 301 and Taconic State Parkway.
While the immediate Mahopac area is known more for its lakes and woodlands than major waterfalls, you can find beautiful water features. The trails in Croton Gorge Park lead to the base of the spectacular New Croton Dam spillway, which creates a stunning man-made waterfall. Many smaller streams and cascades can be found along trails in Fahnestock State Park, especially after rainfall.
