A party of eight to twenty-one people is considered a group. All groups must use designated group campsites. There are 9 group sites available on 5 islands (Sand, Oak, Basswood, Stockton, & Rocky). Group sites provide more space for the larger group size and basic camping amenities (picnic table, fire ring, bear resistant food locker, & nearby privy). Every March, the park conducts a group camping lottery. After the lottery is concluded, all remaining campsites and dates are available for reservation.
Accessibility: Individual site #1 on Stockton Island at Presque Isle and site #3 on Sand Island are Accessible. Groups sites A & B on Stockton at Quarry Bay and group site C on Sand Island are Accessible. All have boardwalks leading from the docks to the campsites and vault toilets, as well as raised wooden decks for tent pads which connect with the boardwalk. Picnic tables and fire rings are all designed to be Accessible. If you need these sites, please request them when making a permit reservation.
Under normal circumstances there's a water tap, vault toilets, an interpretive center featuring map of seasonal prevailing weather conditions, a stuffed bear, and a guestbook.
