Mt. Muller Loop Professional Review and Guide
"From the get-go, the 13.6-mile Mt. Muller loop is difficult and demanding, but the pleasure is worth the pain. The pleasure: Climbs and descents through beautiful woods and incredible wildflower-strewn meadows; views of Mt. Olympus, Lake Crescent, the Strait of Juan de Fuca and Vancouver island, and, on a clear day, Mt. Baker and Glacier Peak. The pain: With only a couple of pedal strokes worth of warm-up, the initial three-mile climb alternates between difficult and punishing, with just a few short respites.
Once on the ridge, there's more climbing and steep roller-coaster sections until a descent with around 30 switchbacks brings you back to the bottom. This is a must-ride for the strong-legged and technically advanced rider. The trail is hard-packed, with some steep, rooty, and rocky sections."
