Thompson's Lake Campground, nestled in the mountains just four miles from the Helderberg Escarpment, is a popular camping ground and recreation area. Conveniently located within
Thacher State Park, this campground offers 140 wooded campsites and is comprised of a sandy beach, mixed hardwood and conifer forests, limestone outcroppings and open fields. Recreational opportunities include a volleyball court, horseshoe pits, a playing field, swingsets, carry-in boat access, canoes, kayaks, and stand-up paddleboards, fishing areas, and nature trails. Interpretive and recreational programs are offered for campers throughout the summer. During the winter, visitors can cross-country ski and ice fish.
The Emma Treadwell Thacher Center is located on Thompson's Lake next to the campground and is accessible to campers. The center opened in July 2001 and offers exhibits, interactive displays, trails for hiking and skiing, and educational programs.
