Sourdough Mountain Trail

Sourdough Mountain Trail Professional Review and Guide

"Grueling is the hike. Awesome are the views. Supreme is the experience. One of the most challenging trails in the North Cascades, the arduous haul to the historical lookout atop Sourdough Mountain is worth every ounce of sweat you’ll expend. And you’ll expend plenty.

A mile straight up and 5.5 on the ground—can you say steep? But a priceless panorama of craggy, spiraling, glacier-hugging, cloud-piercing, unbelievably breathtaking peaks are the payoff. And directly below is an added dividend—Diablo Lake’s surreally turquoise-tinted waters."

Actually, my review is of the Sourdough Creek Trail (which isn't listed in Trails.com, it seems). It is about 3.5 miles RT and begins behind the Diablo Lake Enviro. Learning Center. Only a couple of viewpoints out to other mountains but its beauty is in the gentle upward journey along the Sourdough Creek through various plant communities. The variety of greens resulting from the dappled to deep shade had me snapping away until I decided to just enjoy with my eyes. Ranger Katie clued me in on this charming hike and I thank her (also for her thumbs up on the completely different but awesome Maple Pass hike I managed the next day). The waterfall at the top was underwhelming, tho' may be better earlier in the season. My only regret was coming way past wildflower season.
