From the parking area, cross State Route 20 and use the short connector to the Pacific Crest Trail, also called Bridge Creek Trail here. It descends gently through forest and avalanche paths, crossing small creeks, then enters North Cascades National Park. At the Twisp Pass Trail junction, continue past the Fireweed hiker and stock camps before turning onto the McAlester Creek Trail. That last stretch runs mostly through forest with occasional meadows, climbing steadily before steeper switchbacks reach the lake. The route crosses into Lake Chelan National Recreation Area along the way.
The East Fork of McAlester Creek is unbridged. Snowmelt can make it difficult or impossible to cross in early summer, often June or early July, so check conditions before committing to the long approach.
