Sonic Boom Cave
About Sonic Boom Cave
Sonic Boom Cave is a narrow cave that can be visited on the same dive as a nearby site, reached with a short swim. Swell breaking at the back of the cave produces a distinctive booming sound that can be heard before the entrance is seen. Because the cave is tight and affected by swell, entry is recommended only in calmer conditions. Blue maomao, pāua, and nudibranchs are commonly seen here, with reef fish such as snapper and wrasse outside the cave.
