Nakagurumi is a shallow Kushimoto bay dive with sand and coral roots.
Nakagurumi is a shallow Kushimoto bay dive with sandy stretches, coral roots, and a simple route that rewards calm buoyancy. The site sits close to port and is usually entered by a short boat ride with a rope-assisted drop. It is best on calm, sunny days because the bottom silts easily and visibility can fall when water movement is weak. Small reef fish gather around the structure, with lionfish and juvenile boxfish adding interest.
