Wild Hammer - Grand Cayman

Arch Reef sits off the California coast, a good spot for divers comfortable with colder water and kelp forests. You'll find the namesake arch formation, a natural swim-through that’s always a good photo op. Look out for nudibranchs clinging to the kelp and occasional garibaldi darting between the stalks. It’s a solid dive for those who enjoy exploring the temperate Pacific environment.
