Mirror Lake via the Pacific Crest Trail (PCT)

Snoqualmie Region

updated 2 weeks ago

Mirror Lake is snow-free and in good condition as of late October 2026. The road to the trailhead remains rough, with potholes and occasional ditches, making a high-clearance vehicle recommended by several reports from October 15, October 12, October 11, and October 15. While some noted it was passable with care in sedans, others found it very challenging. Trail obstacles are minor, with a few wet spots or seepage reported, but no significant blowdowns. Fall colors were past their peak in mid-October but still offered beautiful vistas. The lake itself can be windy, impacting reflections, and some reports described a more "party atmosphere" with other visitors, especially on weekends.
