Hyalite Canyon holds well over 100 documented ice routes.

What sets it apart

A local festival each December celebrates the frozen season. It is the kind of specific that turns a passing curiosity into a lasting fascination.

Road plowing keeps the canyon accessible through the coldest months.

Why it matters

Step back, and a bigger picture comes into focus: this is Montana in miniature, rugged and unhurried. Go prepared, respect the conditions, and Montana's backcountry will give back in kind.
