You can always go to recreation.gov website to check the Availability Grid in order to check the availability of any campsite in any campground they serve on any day or days going six months forward. Generally - sites are usually available as walk-ins (also known as First Come First Serve campsites) during the week and most always booked on weekends. Summer has more weekday bookings but usually you can get a walk-in for a single site. Since we are currently under a fire ban (for 2022) availability is generally better. You need propane equipment like a cook stove or fire ring (for a campfire) as the fire ban is likely to go a while and recur in the near future.
We had booked online apx 3 weeks earlier & they ended up sold out for the last weekend of April. Def'ly suggest reserving online. I'm not sure when they sold out -- a great campground.
