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.

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.

Slavery has long been associated with the south, but recent discoveries in the Hudson Valley tell another story. Historical archaeologists at the New York State Museum have recently completed geophysical surveys and archaeological testing at Schuyler Flatts, the Nicoll-Sill House, and Van Schaick Mansion in Albany County. Dr. Michael Lucas will discuss ongoing research into these sites and the findings that give evidence of the practice of slavery. Call 872-0800 for more information.
The hemlock woolly adelgid (HWA) is an invasive forest pest from Asia that kills eastern hemlock trees. These beautiful evergreens are common in the forests of Thacher Park. This workshop, presented by DEC Division of Lands and Forests staff, is appropriate for forest owners, environmental educators, and others who want to learn how to identify HWA and assist with surveying and reporting observations. After the presentation, participants will go out in the field and learn how to identify signs of infestation on nearby hemlocks. Call 872-0800 for more information.
Did you know that the largest living organism on the planet is a fungus? Mycologist John Michellotti explains what mushrooms and fungi are, the ecological functions they serve in the woods, how mushrooms have been utilized historically, how to grow mushrooms, and the medicinal properties that fungi have. There will be easy indoor mushroom growing kits and mushroom health tinctures available for purchase. The fascinating world of Fungi awaits! Call 872-0800 for more information.
