Is there lodging here or is it tent, and rv camping?

They do have cabins and rentals or you can camp out in a tent or you can bring in your RV there's lots of lodging available also around the springs

I saw a lot of tents and a few campers.

Plenty of primitive camping, limited elec/water tent sites, limited RV sites

I saw a lot of tent

They have cabins to rent, and plenty of tent and rv sites.
