It isn't an actual enclosed naval yard. You're free to walk around the area, where there's shops, restaurants, etc. If you want to go further afield you can do tours, or grab the ferry, etc.
When I was there last I was going to do the Segway Tour, but there was a problem with equipment from an earlier tour, so they were short Segways.
