After driving around every overcrowded campground in mammoth lakes we were lucky enough to find this campsite on Dyrt. It had many open spots even in July with beautiful views of nearby mountains. Close walking distance (about .5 miles to a mile depending one where your site is) to a lake and a hiking trail up to devils postpile. We also went to try the hot spring there at night but it was so hot you had to bring up buckets of water from a nearby creek to use it, we heard it is better in the early mornings. Also there are a lot of bears in the area and they are relatively comfortable around humans, one walked through our site and other campers sites while we were there so make sure to keep all food and items that may have scent in the bear boxes provided and not in your vehicle or tent!
