Overnight wilderness permits are required for camping at Third Beach. There is a nominal cost. The NPS may limit how many people are given permits at any one time, but it is an area where permits are generally available even in high usage summer months. Once you have your permit, you pick your own spot along the beach. There not established campsites that can be reserved. More info here:https://www.nps.gov/olym/planyourvisit/third-beach-trail.htm
