Lower Cathedral Lake

Overview

Lower Cathedral Lake is the crowd-pleaser of the Cathedral Lakes pair: a granite-rimmed High Sierra lake framed by Cathedral Peak with Echo and Tresidder Peaks nearby. It’s larger and more open than the upper lake, with classic Yosemite granite slabs and sweeping water-and-peak vistas.

The Hike In (via Cathedral Lakes/John Muir Trail)

You’ll start near the west end of Tuolumne Meadows on the John Muir Trail and climb steadily early on. Most of the vertical happens before you’re around the base of Cathedral Peak. At a signed junction, turn right and descend about 0.5 miles (roughly 100 feet down) to reach Lower Cathedral Lake. Expect mixed granite, gravel, and some rocky/rooty sections. Altitude is real here (trailhead around 8,500 ft; lake near 9,290 ft), so pace yourself.

What You’ll See

The payoff is excellent: a granite bowl wrapped around clear water, backed by jagged peaks. The broad rock shelf on the eastern shore is ideal for sprawling out. If you have the energy, continue along the shoreline to the far west end for a distant look down toward Tenaya Lake.

Conditions to Expect

Early season brings marshy meadows and a few soggy crossings; late season can still deliver cold bursts, fast-moving clouds, even hail. Storms can pop up quickly at these elevations. Mosquitoes are notorious near the lakes when snowmelt lingers—repellent and long layers help a lot.

Best Time to Visit

Come when Tioga Road is open (typically summer to early fall). Start early on weekends to stay ahead of crowds and afternoon weather. Midweek mornings are the calmest. If you’re after reflections, aim for calmer hours and wander to different shores to play the light; the granite slabs on the east side are especially photogenic.

Wildlife and Water

Anglers report brown trout in the lakes. Treat all natural water before drinking. You’re in active bear country—store food properly, even on day hikes when you leave items at the shoreline.

Logistics and Amenities

There are no amenities at the lake—no toilets, no treated water, no trash cans. Pack everything out. The trailhead itself is minimal; plan to use restrooms and fill bottles in the Tuolumne Meadows Visitor Center area when it’s open. Bear lockers are available at the main parking area. Parking has largely shifted to the larger lot by the visitor center, adding about a half-mile of walking each way to reach the trail.

Backpacking Notes

Overnights require a wilderness permit. Bear canisters are required. Camp at least 100 feet from water and beyond the no-camping zone extending several miles from Tuolumne Meadows, per NPS rules. Expect popular quotas; plan ahead.

Is It Worth It?

Yes—though the forested approach can feel long and a bit tedious, the lake itself is spectacular. If you only do one of the Cathedral Lakes, the lower often wins for its big granite lounging slabs and open views.
