While the hike to Crystal Lake isn't long, that doesn't mean it's easy. "The hike to Crystal Lake climbs straight up the hillside in less than a mile and the trail can be steep in some areas," writes Miranda. The steep grade accounts for the "Difficult" trail rating, but other hikers may only consider this to be a moderate hike.

As you survey the view, take a careful look at the Mammoth Crest above you. If you're interested in a more difficult hike, the climb you ascended to reach the lake continues to the top of the Crest, traverses the entire top of the ridge, and then descends back into the Mammoth Lakes Basin via the Duck Pass Trail. The total distance for that loop is 13.1 miles with 3,215 feet of climbing and descending. If you have plenty of energy and supplies, consider tackling that loop, or file it away in the back of your mind for another day.
