Fun interesting moves on good ridge-top granite comparable to the famous ridge climbs of Tuolumne Meadows (but with a shorter easier approach). Wonderful setting in the midst of mountain lakes.

Approach: See Crystal Crag alpine / multi-pitch area
for how to get to parking and trailhead and hike up to Crystal Lake --> see overview map

Then hike about 0.25 mile / 400 meters S around the east side of Crystal Lake, which some ups and downs to reach a flat clearing. Then head cross-country SSE about 0.3 mile / 500 meters on a rising traverse to reach the col on the south side of the Crystal Crag.

Turn sharp L (N) and start scrambling up the South ridge (with moves of class 3 and some rock-hopping opportunities) about 600 ft / 200m to the first tower. (This point could also be reached by steeper climbing up the W side of the ridge - see Aretes of Crystal Crag direct )

Climb: Up (with some downs) along the narrow ridge / arete distance about 600 feet / 275m (low class 5, mostly class 3+4) to the (highest) South summit. Possibly with careful navigation, might be able to keep all the climbing moves at difficulty class 4 or less, but if descending (or retreating) the same way, some of the moves likely will feel like class 5.

In some sections it might be possible to find an easier way below the crest of the ridge on the east side (one guidebook recommends doing this higher on the route), but be careful since this could send loose rock down on the Sport climbers below.

Descent: Return the same way.

alternate Descent: From a little N of the South summit, go down the West face. One guidebook suggests going straight down a short ways, then diagonal Right (NW). We started that way, but then aimed aimed overall toward a little N of the S end of Crystal Lake ... From the crest at first straight down (steep thoughtful moves), then diagonal down + S (thoughtful moves, exposed) into a gully, and down that. In the middle section we hit a dirt track, then lots of loose rock, down to a wide ledge, where we turned SW to get down to the talus field near a large multi-trunk tree.
. One guidebook suggests that this overall section of the W face is class 3, but especially the top section (also a little at the bottom) seemed to require so much thought to find the moves in descent that it should be graded as class 4 (even if it feels like class 3 when climbing up) - or perhaps the guidebook author just knows a better easier route.

alternate Descent: Continue N along the arete, down-climbing to the notch between the South summit and the Middle Summit (low class 5). Perhaps this section can be done at class 4 if done in the upward direction, but some moves as down-climb likely will feel like class 5). From the notch, go down the West with loose rock and dirt. Mostly class 3, but likely a class 4 move will be encountered, especially near the bottom.

Rope less than 30 meters and long slings for the arete sections (possibly a selection of cams). The leader should be skillful in protecting by running the rope around different sides of rocks and horns along the arete.


3-4 miles SW of the town of Mammoth Lakes --> see overview map
