Ausable Chasm, located in Keeseville, New York, is one of the most spectacular natural attractions in the Adirondack Mountains. Carved over thousands of years by the Ausable River, this dramatic sandstone gorge features towering cliffs up to 150 feet high, powerful waterfalls, and crystal-clear rushing water.

Visitors can take guided boat tours through the narrowest parts of the chasm or walk along well-maintained trails and bridges high above the river. Highlights include the famous "Grand Flume," several impressive waterfalls, and stunning viewpoints. The site also offers a nature trail, rock climbing opportunities, and a visitor center with geological exhibits. Known as the "Grand Canyon of the Adirondacks," Ausable Chasm combines raw natural beauty with easy accessibility. It’s especially popular in the fall when the surrounding forest explodes with color.

The area has been a tourist destination since the 1800s and continues to impress visitors with its dramatic scenery and powerful river. A wonderful mix of adventure, photography, and natural wonder — perfect for families, hikers, and anyone exploring the northern Adirondacks.
