Crystal Lake Trail
What to Expect
Safety Advisory
The upper section crosses exposed talus fields with no shade and significant altitude — watch for signs of heat exhaustion and altitude sickness, especially if you drove up from the Central Valley that morning.
Afternoon lightning storms are common from July through September above treeline. If clouds start building by midday, turn around — the exposed granite offers zero shelter.
Trail Details
- 1
Start at the Sawtooth trailhead by 7 AM — the Mineral King road is slow and winding, adding 45 minutes from the valley floor, and afternoon thunderstorms roll in fast above treeline.
- 2
Carry more water than you think you need. The creek crossings early on may be dry by late summer, and there's no reliable water source near the lake itself in drought years.
- 3
The junction with the Monarch Lakes trail is easy to miss on the return — mark it on your GPS or drop a pin, because tired legs and fading light make wrong turns more likely than you'd expect.
