The Siamese Ponds Wilderness Area, an Adirondack Park unit of the Forest Preserve, is located in the towns of Lake Pleasant, Wells and Indian Lake in Hamilton County and the towns of Johnsburg and Thurman in Warren County.

[citation needed] The area contains 33 bodies of water covering 945 acres (3.8 km2), 33 miles (53 km) of foot trails, and 4 lean-tos.

In addition, the area contains a large number of beaver meadows and swamps.

On most of the higher elevations, except those in severely burned spots, spruce and hemlock predominate, while mixed hardwoods and softwoods cover the remainder of the area.

[citation needed] Thirteenth Lake has a small sand beach at the northern end that makes a very desirable spot for picnics, bathing and camping.
