Lost Creek Campground (16 sites for tents only) is located 3 miles southeast of the lake along the Pinnacles Road. It is typically open from early July to mid-October, but it will be closed in 2022.
The finish line for Crater Rim Run. Spacious, restrooms and the little Creek: so cool.
Big sites and great amenities on site including bear box and picnic tables. The portapotty situation was clean and had hand sanitizer. Please note a lot of fine ash will be kicked up in dry conditions.
Biggest complaint is that the campground is not very clearly marked from rim drive and coming from one direction on the drive it's a very sharp turn to go down the road that takes you to the campground from the drive. They're are bathroom and shower facilities but they were closed with Port a potties setup outside them, not a problem for us, but something to note. There are no reservations and limited spots, so make sure to check in early. The price is cheap, 5 dollars to camp and 2.50 with a national parks pass per night. The campgrounds is pretty secluded so the view of the night sky is pretty amazing on a clear night.
The place is actually a mosquito sanctuary over summer and cpnsists in an amazing opportunity to contribute with wildlife preservation. You can be bitten by over 45 different species, they chase you everywhere and love taking rides in cars. Fun for the whole family.
