Frequently Asked Questions

Where can I park to access the Three Lakes and Appalachian Trail Loop?

The most common starting point for this loop is across from Canopus Lake on Route 301, within Clarence Fahnestock State Park. There are two different trailheads for this figure-eight loop, offering flexibility.

What is the terrain like on this hike?

The trail offers varied terrain. It begins with relatively flat, fern-lined paths, transitions to a more challenging section with switchbacks and a steep climb, then becomes rocky before flattening out again. The Appalachian Trail portion undulates through the woods, featuring streams and diverse tree types.

Is the Three Lakes and Appalachian Trail Loop dog-friendly?

Yes, dogs are generally allowed on trails within Clarence Fahnestock State Park, but they must be kept on a leash at all times. Please ensure you clean up after your pet.

What kind of scenery can I expect along the route?

Hikers can expect picturesque views through lush forests, often lined with ferns. Notable water features include Hidden Lake, the scenic John Allen Pond, and glimpses of Canopus Lake. You might also encounter a waterfall along Cold Spring Turnpike and a huge beaver dam. The diverse forest includes maples, oaks, beeches, hemlocks, and poplars.

Do I need a permit or pay an entrance fee for Clarence Fahnestock State Park?

Clarence Fahnestock State Park typically charges a vehicle use fee during peak seasons (usually from spring through fall) for parking. It's advisable to check the official New York State Parks website for current fees and operating hours before your visit, as these can change.

What is the best time of year to hike this loop?

The trail is enjoyable in spring, summer, and fall. Spring offers lush greenery and wildflowers, while autumn provides stunning fall foliage. Summer is also popular, though it can be warmer. Winter hiking is possible but requires appropriate gear for snow and ice conditions.

Does the trail intersect with other well-known paths?

Yes, the route incorporates a significant section of the iconic Appalachian Trail. It also passes through sections of the Moneyhole Mountain Trail, Catfish Loop, Old Mine Railroad Trail, and Charcoal Burners Trail.

Are there any specific points of interest or landmarks to look out for?

Beyond the natural highlights like Hidden Lake and Canopus Lake, hikers might discover the ruins of an old house along the route. There are also potential camping spots near an unnamed lake.

Is public transport available to reach the trailhead?

While direct public transport to the specific trailhead is limited, you may be able to reach nearby towns via Metro-North Railroad (e.g., Cold Spring station) and then arrange for a taxi or ride-share service to the park entrance on Route 301. It's best to plan this in advance.

What should I bring for a hike on the Three Lakes and Appalachian Trail Loop?

Given its moderate difficulty and length, it's recommended to bring plenty of water, snacks, a map or GPS device (like komoot), appropriate hiking footwear, and layers of clothing. Trekking poles can be helpful for the steeper and rocky sections.

Are there any sections of the trail suitable for families or less experienced hikers?

The initial mile of the trail features relatively flat, fern-lined paths through the forest, which could be suitable for families or those looking for a shorter, easier walk. However, the full loop includes moderate inclines, uneven terrain, and steep portions, making the entire route more challenging.
