Although there are no guarantees, it is best to arrive at the park before noon to check for availability. Check-out time at all parks is 11am, therefore, if a guest is checking out then you can move in to the site after they leave. If a campsite is unoccupied, doesn’t have a ‘reserved’ tag on it, and there is nothing in the site, you may also occupy it. Please ensure that you physically have something ON the site in order to claim it (ie. a tent set-up, trailer).
The exception is at Okanagan Lake South Campground where you must check at the gatehouse for campsite availability. At this park you may need to add your name to a Wait list if you do not have a reservation.
