Tallman Mountain State Park

Tallman Mountain State Park is a 687-acre protected area on the Palisades uplands with steep slopes along the Hudson River. Dense woodlands crisscross the grounds with a network of trails that offer river views throughout the property.

The protected area was established in 1928 to save a section of the Palisades cliffs from quarrying operations that had long affected the region. This action preserved the landscape from industrial extraction and kept it as a natural space for future use.

The park serves as a learning space where visitors encounter the ecological systems of the Hudson River National Estuarine Research Reserve. Schools and research groups use the grounds to study how the river and forest connect and influence each other.

The five miles of trails are open year-round from dawn to dusk, crossing the grounds at varying difficulty levels for different abilities. Additional facilities include picnic areas, tennis courts, and a running track for visitors seeking other activities.

The grounds contain part of Piermont Marsh, a brackish tidal wetland that shifts its appearance with each tide cycle of the Hudson. This tidal movement creates constantly changing landscapes that offer visitors different visual experiences depending on when they visit.
