A fun singletrack trail in either direction with an opportunity for a dip in an alpine lake.

Features -none-

Not rideable until the snow has melted, which could be into early June. If you're driving to the eastern trailhead, low clearance vehicles are not recommended after the turn onto Lost Lake Spur. No problems driving to the western trailhead.


Starting at about 9 miles up from the valley floor of North Frontage Road, Lost Lake Trail is out there. It can be ridden in either direction, or as an out-and-back. Parking is available at either end of the trail.

If riding east to west, you could connect to Buffehr Creek Trail descent. If riding west to east, you could connect to Son of Middle Creek. It's not particularly difficult in either direction, and riding east to west, there is only 1 short/steep climb. The trail does require skill with negotiating exposed roots and loose rocks riding in either direction.

The trail is obvious and easy to follow, except for one area (see info icon): If riding east to west, once you see the lake, follow the trail off to the right with the lake on your left. If riding west to east, once you see the lake, follow the trail about 1/4 of the way around the lake or about 1/4 mile, then veer to your left with the lake at your back.

Ride east to west if you want (this direction is mapped here):
- more challenging climbing with a few hike-a-bike sections
- a super fun, fast and steady descent
- to connect to Buffehr Creek Trail

Ride west to east if you want:
- to climb steadily rather than steeply
- to connect to Son of Middle Creek

Or ride out and back from either direction!

3 stars. The trail itself is excellent in either direction. Getting to it is either a lot of fire road climbing or driving to enjoy about 4 miles of singletrack.

The trail is not particularly clear at this point. From this viewpoint, it comes from behind and continues to the right.
