Thacher State Park is situated along the Helderberg Escarpment, one of the richest fossil-bearing formations in the world. Even as it safeguards six miles of limestone cliff-face, rock-strewn slopes, woodland and open fields, the park provides a marvelous panorama of the Hudson-Mohawk Valleys and the Adirondack and Green Mountains. The park has volleyball courts, playgrounds, ball fields and numerous picnic areas with nine reservable shelters. Interpretive programs are offered year-round, including guided tours of the famous Indian Ladder Trail. There are over 25 additional miles of trails for summer hiking and mountain biking, and winter cross-country skiing, snowshoeing, hiking, and snowmobiling.
Camping is available at this park at Thompson's Lake Campground, which features 140 campsites with options of private wooded sites and open, adjacent sites. Sites can accommodate tents or RVs and are all close to restroom and shower facilities.

The Emma Treadwell Thacher Nature Center is located two miles from the Overlook on Thompson's Lake. The center offers exhibits, interactive displays, trails for hiking and skiing, and educational programs.

Ask a Naturalist!
Q: Can we explore the cliff above and below the Indian Ladder Trail?
A: Please stay on the trail! The slopes can be dangerous with loose rocks and slippery mud. Climbing up the steep banks destroys vegetation and creates erosion problems. Many of the mosses take decades to establish and minutes to destroy. The trail is narrow and the steep slopes are difficult to stabilize. Please stay on the trail to preserve this fragile environment.
Q: Where can we go to see fossils?
A: Much of the rock in the park is limestone and contains fossils of shelled marine animals. They are easiest to find on rocks in streambeds, in the stone wall at the Overlook, and in bare rock exposed along the Cliff Top Trail. Enjoy hunting for fossils, but please remember that collecting is prohibited in state parks.
Q: When and where can we see waterfalls in the park?
A: There are two waterfalls that cascade over the Indian Ladder Trail, one at Hop Field, and at Paint Mine picnic areas. Early spring is best, and after heavy rains in summer and fall. During much the summer, the waterfalls can be completely dry.
Did You Know?
- DID YOU KNOW? In the late 1800s, the Helderbergs became a popular tourist destination and city dwellers hired buggies to bring them up to the resort hotels near the Helderberg Lakes.
- CHECK IT OUT! On a hot summer day, the narrow cave along the Indian Ladder Trail's cliff wall provides cool relief.
- DID YOU KNOW? The Indian Ladder Trail got its name from the felled trees that Native Americans used to climb over the Helderberg Escarpment on their journey between the western hills of the Schoharie Valley and the Hudson River Valley.
"Cliffs Higher Than the Palisades" was just one of the superlatives used to describe John Boyd Thacher State Park after its acquisition in 1914. Learn more about the history of Thacher State Park.
Key BCA Criteria:
- Migratory concentration site
- Diverse species concentration site
- Species at risk site
The John Boyd Thacher/Thompson's Lake BCA consists of portions of two nearly contiguous State Parks in Albany County. John Boyd Thacher sits atop the Helderberg escarpment, a 100 foot high calcareous cliff. The BCA is especially important because its diverse habitats support a wide variety of birds of prey. Thacher is dominated by forested uplands. The Thompson's Lake area consists of additional upland forest, old fields and a bur oak-black ash swamp adjacent to the lake. The lake itself is not owned by OPRHP.
There are 171 species of birds that have been identified within the J.B. Thacher and Thompson's Lake BCA, of which 102 are confirmed or probable breeders, including: Sharp-shinned hawk (Special Concern), Cooper's Hawk (Special Concern), Northern Goshawk (Special Concern) and Golden-winged Warbler (Special Concern). The forests support some of the area's highest densities of breeding songbirds such as Hermit Thrush, Winter Wren, Magnolia, Black-throated Blue, Black-throated Green, Blackburnian, Canada and Worm-eating Warblers and Louisiana and Northern Waterthrushes. J. B. Thacher supported the first recent regional nesting of Common Ravens and is now the nucleus for the population in the area.
All persons hunting within the boundaries of the permitted hunting area of Thacher State Park must have a valid NYS hunting license, archery license, muzzle loading license and/or turkey permit as required by Environmental Conservation Law. A special permit, issued by Thacher State Park, is also required. Permits can be obtained at the park office at no charge.
Rifles of any caliber or handgun of any type is strictly prohibited. Muzzle loader or shotgun only. Bow hunting in designated areas. With the exception that all hunting ends on March 31st of each year, the hunting schedule follows the hunting season as outlined by New York State DEC for NYSDEC wildlife management unit (WMU) 4H; this is considered the "Southern Zone." All NYSDEC regulations and provisions pertaining to WMU 4H apply. Hunting within 500 feet of any building or road is strictly prohibited. No structures of any kind. Tree stands must be climber style or lock on. All tree stands must be removed daily.
Hunters must display the park issued parking registration form on the dashboard whenever parked in one of the designated hunting parking areas. Hunters must carry the park issued hunting permit on their person at all times when hunting in the park. The permit must be displayed upon request to any park employee or officer. Sign in/sign out sheets will be placed on the map boxes in the three designated parking areas. Hunters are required to sign in and out each day they hunt.
Hunting permits include a report; the report must be completed and returned to the park office by March 31st.
Hunting is permitted from sunrise to sunset.
*Please note: Hunting is not permitted within 500 feet of any building, road, playground, or parking lot, and all trails are considered safety zones where hunting is not allowed.
Descend the cliff and learn about the geologic and cultural history of the Helderbergs on this scenic and historic trail. See underground streams, look for fossils and step inside the crevice cave along the trail. Wear sturdy shoes and meet at the Indian Ladder picnic area. Walk lasts about 1.5 hours. Call 518-872-0800 to register.
The rocks in Thacher Park were historically thought to be nicely layered. Recent discoveries show that the rocks are actually folded and faulted. Learn about how we are refining our understanding of the park's geology and how it serves as a transition between the geology to the west and that to the south. Meet leader Thom Engel at Hop Field picnic area. Call 518-872-0800 to register and for more information.
