Ten Lakes
What to Expect
Safety Advisory
The upper trail crosses exposed granite slabs with minimal shade — afternoon thunderstorms are common from July through September. If clouds start building, do not linger above treeline. Lightning on open granite is no joke.
Snow can obscure the trail near the pass well into July. Bring a GPS track or downloaded map — cairns are sparse and easy to lose on the slabs.

Pro Tips
Start by 7 AM from the Ten Lakes trailhead on Tioga Road (mile marker T-21) — the exposed granite sections above treeline turn punishing by midday, and you want to be descending by early afternoon.
There's no reliable water between the trailhead and the lakes themselves in late season, so carry at least three liters per person. In July, snowmelt streams along the upper trail can supplement your supply — bring a filter.
The best lake for lunch and photography is Grant Lake (the largest in the basin), where you get clean reflections of the surrounding granite peaks in the morning light. Scramble up the low ridge east of the lake for a panoramic view of the entire basin.
