Hilo Bay is partially protected by a reef located in relatively shallow waters, named Blonde Reef after Lord Byron's vessel, HMS Blonde, 

This reef is the foundation of the crescent-shaped breakwater constructed in 1929 to protect the Hilo harbor from storms and reaches about 23 feet deep, with occasional pockets extending to 40 feet.

Snorkel and swim between schools of fish and admire a wide variety of colorful, inquisitive marine life.
