What to Expect

Starting from the trailhead along Tioga Road, Cathedral Lakes eases you in with a deceptively gentle climb through a lodgepole pine forest before the trail starts earning its reputation. The steady ascent — about a thousand feet spread over nearly four miles — never gets brutal, but it's persistent enough to remind you that you're hiking above 8,500 feet. The forest opens up as you approach the Cathedral Lakes basin, and suddenly you're face-to-face with Cathedral Peak, a granite spire that looks like it was designed by a Gothic architect with a geology degree. A spur trail drops down to Lower Cathedral Lake, which sits in a meadow-ringed bowl that reflects the peak like a mirror on calm mornings. Upper Cathedral Lake is the main destination, tucked right beneath the peak's flanks with a rawer, more alpine feel. This is the trail for hikers who want a High Sierra payoff without committing to a death march.

Safety Advisory

The trail sits between 8,500 and 9,500 feet — visitors coming straight from sea level should expect to feel the altitude. Headaches and shortness of breath are common if you haven't acclimatized for at least a day. Slow your pace and hydrate aggressively.

Afternoon thunderstorms roll in fast from July through September, and the exposed granite around both lakes is the last place you want to be when lightning starts. Check the sky constantly after noon and be prepared to retreat into the tree line.

Pro Tips

Trail Tip

Start before 8 AM to snag parking at the Cathedral Lakes Trailhead on Tioga Road — by mid-morning on summer weekends, cars line the road for a quarter mile in both directions, and rangers will turn you away.

Trail Tip

Hit Lower Cathedral Lake first via the spur trail on the way up, not on the way back when your legs are toast. The short but steep descent to the lower lake is far more pleasant with fresh knees, and the morning light on the water is worth the detour.

Trail Tip

The granite slabs along Upper Cathedral Lake's eastern shore make the best lunch spot in the Tuolumne high country — flat, sun-warmed, and positioned perfectly for photographing Cathedral Peak's reflection without other hikers in the frame.
