This scenic singletrack trail run begins at Primrose trailhead on the southern end of Kenai Lake and climbs ~1,700 ft to Lost Lake at the base of Mt. Ascension. At this point, the Primrose trail connects in to the USFS Lost Lake Summer Trail
which descends to the Bear Creek trailhead while providing views (on a clear day) of Seward and Resurrection Bay.
This trail is most commonly run north to south from Primrose to Bear Creek with a car shuttle.
