Young Lakes
What to Expect
Safety Advisory
You're hiking above 9,000 feet for most of this route — if you drove up from the valley that morning, the altitude can hit harder than expected. Give yourself a day to acclimate in Tuolumne if possible.
Afternoon thunderstorms are common from July through September. The upper lakes sit in exposed granite basins with zero shelter, so plan to be heading down by early afternoon.
Trail Details
Pro Tips
Start from the Dog Lake trailhead off Tioga Road rather than the Glen Aulin route — it's more direct and you avoid the Cathedral Creek crossing that can be sketchy in early season.
The trail is exposed above treeline for the final push to the lakes, so start early and carry more water than you think you need — there's reliable water at the lakes but the approach can be bone-dry by August.
Lower Young Lake gets all the foot traffic. If you have the gas, push to the second or third lake for a lunch spot where you might not see another soul, with Ragged Peak reflected in water so still it looks fake.
