Lake Ann & Heather Pass

From Rainy Pass, the counterclockwise route climbs forest to the Lake Ann junction about 1.25 miles in. Visiting the lakeshore adds a 0.6-mile return spur. The main loop instead traverses above Lake Ann and reaches Heather Pass, then continues along the ridge toward Maple Pass with increasingly open basin and mountain views.

High Traverse & Descent

The upper traverse follows steep hillsides near the national-park boundary. Beyond Maple Pass, switchbacks descend through forest; the final 2.5 miles lose roughly 1,700 feet. The loop joins the paved Rainy Lake approach for its last half mile back to the parking area. Rainy Lake itself is a separate spur, just as the Lake Ann visit is additional to the standard loop.

Terrain Along the Route

Forest gives way to subalpine slopes, talus and exposed ridge trail above Lake Ann.
