It's a day hike with a good cardio work out that almost anyone can make. Nothing too strenuous (besides the elevation gain) but worth the rewards.
You will start out at the Big Meadow trailhead at the Luther Pass parking lot. It's three miles one way.
Near the end of the hike just before the lake the rock formations are prime...big trees, a crystal stream. The trail is well defined and easy going even though it's an 1100 foot gain in elevation.
