Visit one of the best old-growth hikes in the North Cascades, with views of a vivid blue lake and jagged, snowy peaks thrown in for good measure. Wander for just a handful of miles, or hike its full 24-mile length — it's a good early season backpack or a fun day hike.
The trail is aptly named, since the valley it traverses is beaver habitat. But the still waters that beavers love also means bugs — come prepared to ward of mosquitos in summertime.
The Big Beaver trail has a junction with the Little Beaver Trail a mile downstream of Stillwell camp. From here, hikers can continue on the Little Beaver Trail for 10 more miles to Ross Lake, or head upstream 6 miles to Whatcom Pass.
