Here are 10 of the most outlandish and unique rock formations in New York worth every mile of hiking and rough driving to see:
- Thunder Rocks – Allegany State Park
These giant conglomerate rock formations create a city-like landscape with caves and crevices, perfect for climbing and exploring. It’s a popular spot with varied difficulty levels for all ages. - Rock City Park – Olean
This private park boasts the world’s largest exposure of conglomerate rock with towering rock formations, caves, and passageways. It’s a cool, shaded area perfect for adventure photography and discovery. - Rock City State Forest
A lesser-known, remote collection of massive conglomerate rocks with tunnels and crevices. It’s rarely crowded and offers freedom to climb and explore in a wild natural setting, though it’s buggy and without facilities. - Ice Caves of the Shawangunks – Ulster County
Cold pockets within these deep crevasses slice through Silurian rocks, allowing solid ice patches to persist year-round. It requires some hiking, but the unique ice formations inside the caves make it worth the trek. - Summit Rock and Vista Rock – Central Park, NYC
These natural bedrock outcrops shaped by glaciers rise prominently in Central Park. They’ve been integrated into the park’s design and offer vantage points and rustic charm right in the middle of the city. - Mohonk Preserve – Near New Paltz
Massive Silurian conglomerate cliffs popular with rock climbers, surrounded by beautiful gardens and vast hiking trails. It’s a perfect blend of geological spectacle and serene natural beauty. - Port Jervis Gorge
Along Route 97 near Port Jervis, steep-walled river canyon cliffs hold marine fossils and Devonian sedimentary rocks. The scenic roadway offers dramatic views of these geological treasures. - Highland Mills Railroad Cut
An exceptional exposure of Devonian shales, limestone, and sandstones, this railroad cut is a favorite among geology field trips, though caution is needed due to passing trains. - South Mountain Reservation
This forested ridge features exposed basaltic volcanic flows and waterfalls, with rugged terrain and scenic views of Manhattan’s skyline from a distance. - Natural Stone Bridge and Caves (Nearby Lake George)
A remarkable natural rock bridge and cave system that make for fascinating exploration and stunning scenery, often considered a highlight amongst New York’s geological wonders.
These rock formations showcase the incredible geological diversity across New York State—from urban bedrock outcrops to wild conglomerate “rock cities” and glacier-sculpted caves. Each destination rewards visitors with unique natural wonders, challenging hikes, and memorable experiences.
