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
You 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.
Trail Wisdom
Start Early
Arrive at opening to avoid tour groups and catch morning light in the gorge for better photos and quieter trails.
Wear Grippy Shoes
Boardwalks and stone steps can be wet and slick—sturdy hiking shoes with good tread reduce slips.
Combine Walk and Water
Book a guided river tour if you want close-up river action—staffed trips include flotation and instruction.
Respect Closures
Trail sections may close seasonally for safety; follow posted rules and don’t shortcut barriers.

Seasonal Guide
spring

Best for: ice formations, quiet solitude, winter photography
Challenges: ice on boardwalks, limited access, cold
Winter transforms the chasm into an ice-sculpted space; lower trails and tours may be closed—check availability before visiting.
