There are fire rings, but their use probably depends on the fire danger.

Usually. Check fire restrictions, first. There's an info sign at the entrance to the campground.

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

Jose, I believe the fire restrictions have been lifted. Please confirm on the BLM website. Have a great day.

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.

Yes, but check for local restrictions when you go. In high fire season, they may not allow them.
