Lost Lake Trail

Various • 15 mi • 2000 ft

A long day trip or a 2-to-3-day backpack to a large alpine lake in the Kenai Mountains. Lost Lake is an alpine lake 2 miles long, set at the edge of a huge expanse of alpine country. Long, low tundra ridges finger into the lake at several points, and many smaller lakes and ponds dot the low hills to the east of the lake. To the west, Mount Ascension looms more than 3,000 feet above. Good camping, fishing, and miles of alpine rambling are the big draws to Lost Lake. An alpine cross-country route to the west leads across miles of tundra, and Mount Ascension attracts mountaineers. Special features: Alpine meadows, tundra rambling, fishing, and one fee cabin near the trail.

Extremely beautiful views once you get up to the lake. Did the traverse with a friend starting on the Primrose side. Did not think it was a very difficult hike. Took just under 5 hours to complete the traverse. Definitely recommend backpacking in and camping at the lake and then taking the time to further explore the area. Great trail to run (yes, lots of people run it and there is a race on the trail in late August) and plenty of mountain bikers. Great hike for dogs as there is lots of room for dogs to run once get up to the lake.
