A peak scramble between Dingford Creek and the Middle Fork Snoqualmie River. Routefinding experience, gear and expertise required.
Big Snow Mountain is most commonly climbed via the boot path to Hardscrabble Lakes, which starts about 1/2 mile below the Hardscrabble Horse Camp on the old Middle Fork Snoqualmie River Road. This road is gated at Dingford Creek, so a road walk of nearly 7 miles is required before reaching the trail.
Another common route for climbing Big Snow is via Myrtle Lake on the Dingford Creek Trail. The route passes by Big Snow Lake and Snowflake Lake on the way up the NW side of the mountain.
