This peak, referred to by some as "the lightning rod of the Cascades," is a spectacular pinnacle north of Crater Lake. It is easier to climb than it looks, but you must be comfortable with some exposure.

The trailhead is on the east side of Diamond Lake, near the lake's south end, along state route 138. It is labeled "Mt. Thielsen Trail." The trail climbs up through woods, eventually meeting the Pacific Crest Trail.

Above the Crest trail, the trail deteriorates into a climbers' trail through scree. This part is not much fun. Eventually, you will reach the south side of the summit block. The climbing here is class 3; what is claimed to be the best route is marked with paint blotches on the rock. If some party members are nervous about exposure, a rope would be a good idea.

Gain is just about 4000' with mileage of perhaps 8 miles RT.
