Lost Lake Trail
The route moves from spruce through hemlock into open tundra and lake country, with options for an out-and-back or point-to-point using the Primrose side.

A long forest climb opens onto subalpine lakes and broad Kenai Mountain terrain. The route moves from spruce through hemlock into open tundra and lake country, with options for an out-and-back or point-to-point using the Primrose side. Snow and saturated trail often linger.
Decide between Lost Lake trailhead and the Primrose traverse before driving, then set a turnaround that protects the long descent. Bikes, hikers, snowmachines, weather, and bears share the corridor by season; two similarly named trailheads complicate shuttles. Rather than treating the stop as a backdrop, use subalpine lake to understand why Kenai Mountains belongs here.
