The Green Lake to Round Lake Trail offers an easy 3.7-mile (6.0 km) hike through a landscape of vibrant, unusually colored lakes and ancient forests. With only 99 feet (30 metres) of elevation gain, this 1 hour and 33 minute route is perfect for a relaxed outing. You'll experience continuous views of the emerald green and turquoise waters of both Green Lake and Round Lake, winding through sections of old-growth forest on varied surfaces from paved paths to wood chips.
To plan your visit, head to Green Lakes State Park in Central New York, where the trail is located. Parking is available within the park, providing convenient trailhead access. This accessible route is popular with photographers and nature enthusiasts, so an early morning or late afternoon start might offer a more serene experience.
What makes this trail truly special are the two meromictic lakes it encircles, Green Lake and Round Lake. These glacially-carved lakes have distinct water layers that don't mix, leading to their unique colors and exceptional clarity. Round Lake is even designated a National Natural Landmark due to its significant geological features and ability to preserve ancient plant and animal remains.

The Green Lake to Round Lake Trail is generally considered easy.

Beyond the stunning lakes, you can observe unique reef-like formations made of marl, encrusted with algae, mosses, sponges, and fallen trees, particularly at Deadman's Point on Green Lake. Benches are also available for resting and enjoying the views.
