Did one night here on a long road trip where a quick stop in Crater Lake was on the sightseeing list. There were a few RV's with generators running and a large group that gathered in and spent the night inside the warming station, so with COVID we never went inside, despite a friendly invite to join them. The main lot is level with plenty of space to spread out from others. Enjoying having fire rings and pit toilets, which was a nice bonus for a free (with pass) Sno-Park.
