South of Anchorage on the Kenai Peninsula, a combination of the Lost Lake Trail (7.6 mi./2000' climb) with the Primrose Trail (8 mi./2000’ descent) makes for a great adventure through lush arctic plateaus with vistas of glacial mountain tops. The mountain bike ride starts off Sewards Highway with a climb up Lost Lake Trail through dense Alaskan Rain Forest. As the forest breaks, there are magnificent views of the Resurrection Peaks and nearby waterfalls.
Near the summit, the wildflower lined trail splits with one track continuing to Lost Lake and the other becoming the Primrose Trail running across a vast ridge top. The Primrose drops fast back into primeval forest and eventually ends back on Sewards Highway, 15 miles away from the car park.
The Lost Lake trailhead is located 1.5 miles north of the Glacier Road exit of the Sewards Highway (SR 9).
The Primrose trailhead is located at the south end of Kenai Lake on FS953 off Sewards Highway (SR 9).
Overall, Primrose - Lost Lake Trail is the 16th most popular mountain bike trail of all 26 mountain biking rides in Alaska.
