Coldwater Campground at Mammoth Lakes, California (Guide + Reviews)
Overview
Coldwater Campground is nestled high above Mammoth Lakes at the end of Lake Mary Road in the Inyo National Forest. Sitting at 9,000 feet, it’s surrounded by lodgepole pines and alpine streams, just steps from Lake Mary and Coldwater Creek. This is classic Sierra Nevada camping — crisp mornings, trout fishing, and endless trailheads right from camp.
What Campers Are Saying
Overall vibe: “Peaceful and perfectly cool.” Campers love the forest shade, mountain air, and proximity to the lakes. Families come for fishing and swimming; hikers stay for easy trail access. It’s cozy, clean, and feels far removed from town — even though it’s just a short drive away.
Highlights
- Fishing paradise: Coldwater Creek and Lake Mary are stocked with trout all summer.
- Trail access: Duck Pass Trail and Emerald Lake Trail start right near the campground.
- Scenery: towering peaks, waterfalls, and thick pine forest.
- Cool temperatures: highs in the 70s even in July and August.
Frictions to plan around
- High elevation: 9,000 ft — take it slow the first day if you’re not acclimated.
- Short season: typically late June through mid-September due to snow.
- Bear activity: use lockers — this is prime bear country.
- Limited cell service: expect no bars — disconnect and enjoy it.
