Although technically this is the Lost Lake trailhead, you might sometimes see it referred to simply as the "south" trailhead. Most riders travel from south to north here, because the uphill portion is much more rideable from the south side. However, you could turn this into a round trip; set up a car shuttle between this trailhead and the Primrose trailhead, at the north end of the trail; or turn the whole thing into a giant loop by splitting off onto the Meridian Lake trail, although this last option requires a short distance of riding on the narrow, winding Seward Highway.
