Mile-Long Cataract Club

Hike to Cataract Falls from Alpine Dam at Mount Tam

02.19.2025

In winter after heavy rains, the north flank of Mount Tam glows with flows. The nearly mile-long series of waterfalls—Cataract Falls—transforms into a supercharged spectacle. The roar of the falls fills Cataract Canyon, an ideal place to hike after rains.

Starting at Alpine Dam, a 1.6-mile (one-way) narrow trail threads through redwoods and ferns along Cataract Creek. The first mile is a waterfall wonderland—at least half a dozen flows follow in short order, snap-crackle fast.

Continue along the creek following the wooden and stone stairs: Falls just keep appearing around every corner, each about 20 to 30 feet high. It’s flow time!

The Cataract Trail is on Marin Municipal Water District land. From Sir Francis Drake Blvd. in Fairfax, turn left onto Pacheco and immediately right onto Broadway. Turn left on Bolinas-Fairfax Rd. (aka Bolinas Rd.) and drive 8 miles to Alpine Dam. Cross the dam and park at one of the dirt pullouts within 0.1 mile of the dam. The trailhead is up on the left. Dog-friendly!

NOTE: Always check park and trail statuses before heading out. After heavy rains, trail conditions can be wet and slick. Exercise good judgment and caution.
