how much does it cost and d i need to make a reservations
Although not necessarily "required" in all cases, it's highly recommended to make a reservation for improved campgrounds like Holcomb Valley, Serrano, Barton Flats etc. You don't want to get there and find out someone scored the last available spot 15 minutes before you arrived. Yellow Post campsites are first come/first served spots (no reservations can be made). Dispersed camping (basically, anywhere off trail in SBNF) don't need reservations.
