Generally yes, they have large metal barrel firepits at each site, but DO check with the Eastern Sierra Interagency Office in Lone Pine for restrictions that might be in place temporarily. https://www.fs.usda.gov/recarea/inyo/recarea/?recid=20698
I don't know what the current rules are but given the dry situation in California, I doubt it. You could look on their website in California.gov I think.
