North Fork Lone Pine Creek Trail

This trail is considered extra difficult, often rated as 'Double Black Diamond'. It's a primitive route with rugged terrain, steep ascents, and can be challenging to follow. Expect scrambling and some 3rd class climbing, requiring skills in navigating over rock, snow, and ice. It is not recommended for inexperienced wilderness travelers.

While the distance is approximately 3.0 to 3.1 miles one-way to Iceberg Lake, its extreme difficulty and significant elevation gain (around 3,912 feet) make it feel much longer. Plan for a full day or multi-day trip, depending on your pace and whether you're continuing to higher climbing objectives.
