    Butterfly Bay offers a calm entry, making it a good spot for newer divers or those looking for a relaxed dive. We typically find schools of snapper weaving through the soft corals here. Look closely, and you might spot a few nudibranchs grazing on the shallower reef. It's a pleasant, easy dive, best enjoyed at a leisurely pace.
