Use the Guam dive-spot directory to shortlist sites, then open the individual records for Gun Beach or Gab Gab 2 if either is on your list.
An entry-style label answers how a dive begins. Check permission and the meeting arrangements separately before planning your journey.
Send your operator or the relevant access contact a specific question:
I am considering [site] on [date]. What access permission, if any, do I need? Where should I meet you, and is that the same place as the water entry or boat departure? Is equipment transport included? What should I confirm again before setting out?
If access or the departure arrangement is still unclear, keep the site provisional while you compare another option.
