What to Expect on the Trail

The hike to Garnet Lake is moderately strenuous, with steep ascents, rocky paths, and a few switchbacks. It’s not the easiest trail, but the reward is worth the effort.

Terrain Highlights:

• Forest trails – The first few miles wind through a mix of pine and fir trees, providing cool shade.
• Granite slopes – Classic Sierra Nevada landscapes with exposed rock faces and sweeping views.
• Shadow Creek crossings – Beautiful water features add to the rugged charm of the hike.
• Steep climbs – Some sections can be challenging, especially near Shadow Lake and the final ascent to Garnet Lake.

The best time to hike is from July to September, when the snow has melted and the trails are fully accessible.

Camping at Garnet Lake

For those wanting to wake up to one of the best alpine sunrises in California, Garnet Lake offers fantastic backcountry camping options.

Where to camp:

• The best campsites are on the north and east sides of the lake, past the footbridge at the outlet.
• Camping is prohibited within ¼ mile of the lake’s outlet, so make sure to set up beyond this area.
• Expect rocky terrain—bring a good sleeping pad for comfort.

Leave No Trace:

• Fires are not allowed due to the high elevation.
• Pack out all trash and food waste to protect the delicate ecosystem.
