Rainbow Lake Trail
The wild requires that we learn the terrain, nod to all the plants and animals and birds, ford the streams and cross the ridges, and tell a good story when we get back home.

The Rainbow Lake Trail provides access to one of the park's steepest passes, Bowan Pass, as well as deep blue Rainbow Lake. It is primarily a backpacker or advanced stock use trail, since it lies deep within the park and is accesed via several other trails. Primarily, it is part of the popular Rainbow-McAlester Lakes loop, and makes a beautiful fall destination for rugged hikers, or for those who enjoy getting away from it all and fishing.
Backcountry Camping: A backcountry permit is required for all overnight stays. Permits are limited. There are numerous stock and hiker camps spaced along the trail, although some of the camps are small and do not hold larger parties.
Access from Stehekin: From Stehekin, take the bus or walk to the Rainbow Loop Trailhead. Follow the Rainbow Loop and then the Rainbow Creek Trails 5 miles (8 km) to the start of the Rainbow Lake Trail. Look for real rainbows as you hike-- with all these "rainbow" trails there must be some here somewhere!
Access from SR 20: Drive State Route 20 to mile 159, just over one mile (1.9 km) east of Rainy Pass. The Bridge Creek Trailhead parking lot is located on the north side of the highway. A Northwest Forest Pass or federal recreation access pass is required at this USFS trailhead, and is available at any ranger station. Cross the highway and pick up the Bridge Creek Trail, which is part of the Pacific Crest Trail, and follow it 6 miles (10 km) to the junction with the Rainbow Lake Trail, at South Fork Camp. This end of the trail is also sometimes called the South Fork Trail.
