Humbug Spires WSA

This 11,175-acre roadless area is located 26 miles south of Butte. Impressive granite outcroppings, part of the Boulder Batholith, rise 300-600 feet and provide outstanding rockclimbing opportunities, most of which range from 5.5 to 5.7 in difficulty, although routes to challenge all levels of ability are present. A three-mile (one way) trail starts at the parking area and winds along the creek through an old-growth forest, and then climbs a ridge and eventually reaches the “Wedge," one of the more prominent spires.


Hiking, rockclimbing, sightseeing, photography, horseback riding, wildlife viewing, primitive camping, and small stream fishing.

*Offsite developed camping is available five miles away at the Divide Bridge Campground.

*When hiking, carry water, a compass, and a copy of the site map found on the back of the brochure.
