Campgrounds are available to individuals and groups for a charge of $5.00 per person/per day. To assure campground space, all reservations must be made through the Keepers by phone or radio. Potable (drinking) water cannot be provided. Campers must supply their own drinking water, food, shelter, and cooking facilities.  An outdoor composting toilet is provided at campground.

The island's wildlife sanctuary status prohibits the landing of pets. 

The light towers are open to climb for the scenic views at the discretion of the Resident Keeper. The exterior deck and the old glassed-in site of the original beacon in the North Tower are open to climbers (159 steps) for a 360-degree view of the ocean and the mainland. The top deck of the South Tower is not open to visitors since it houses the Coast Guard’s red flashing navigation beacon. Walking trails to scenic views and points of interest are maintained by Committee and Association volunteer workers. 

The North Tower is not open for public access duriing the 2019 season.   Access to the South Tower is at the keeper's discretion and is to the light chamber only; there is no access to the outside gallery.
