Ausable Chasm: Walking the Grand Canyon of the Adirondacks
A short, dramatic gorge with carved rock walls, wooden walkways and scenic river tours—accessible Adirondack drama
Keeseville, New York•By Robert Eric Crews•Land Adventures,Water Activities,Wildlife Nature•October•fall
Continue ReadingYou step down onto a wooden walkway and the world shifts. The timber vibrates underfoot while the Ausable River, a narrow ribbon at this point, rumbles and bangs against polished granite walls that have been knifed by water for millennia. Spray catches sunlight and throws it like confetti across the narrow throat of the gorge; the air turns cooler, greener. The chasm doesn’t whisper— it speaks, and if you listen, the conversation is all river and stone.
Duration1–2 hours (main loop); add 1–2 hours for guided river trips

Shoot early or late for soft side-light on the rock walls; use a polarizer to cut water glare and saturate foliage. For long exposures of rapids, carry a small tripod or use a rock as stabilizer; bracket exposures in the narrow gorge where shadows and highlights sit close together.
