Lake Lillian

Snoqualmie Region

updated 1 week ago

Lake Lillian is currently experiencing mixed conditions. While the trail was reported as snow-free on October 10, a more recent report from November 1 indicates snow is present and can be deep, making travel difficult. Spikes were helpful on icy sections, but shin-deep powder was encountered further along. The road access to the trailhead was reported as impassable and closed on October 10, and August 11. However, one report from November 1 states the road is suitable for all vehicles, suggesting a potential change in access. There are no reported bug issues.
