Base 1 Muck Site is a sheltered Tulagi Harbour dive where wartime repair debris now sits beneath a slow, critter-rich bay floor. Landing craft, munitions, small boats, and aircraft parts break up the bottom, while plate corals and juvenile sweetlips add life to the wreckage. It is a careful look-around dive rather than a fast pass, and the bay setting keeps the plan focused on detail instead of open-water exposure.
