Climbing the Fremont Glacier
From Colonial Creek Campground on SR 20 at Diablo Lake, hike the Thunder Creek Trail about 18 mi toward Park Creek Pass, losing and regaining 1,000 ft past Junction Camp and fording Thunder Creek below Thunder Basin. Near the last switchbacks, traverse northeast on a faint climbers path to the gentle Fremont Glacier. A snow finger leads to the summit ridge, then exposed Class 3 to 4 ledges on the east side reach the top; some parties rappel the summit block. The snow finger can melt out late season. Plan 3 to 4 days with a North Cascades backcountry permit.
