Oahu's Best Dive Sites 

As home to Surf N Sea, Oahu offers both convenience and diversity in its dive sites, from calm reefs to exciting wrecks. 

Shark's Cove (North Shore) 

Overall, Sharks Cove is a fantastic “locals” spot with tons of amazing lava rock formations. Hawaiian Monk Seal and Green Sea Turtle spottings are frequent as well. It’s a unique dive spot and a must-see if you’re an already experienced scuba diver visiting Oahu.  

While Shark's Cove is an exciting dive destination, commercial tours and guided dives are no longer permitted here due to ongoing reef restoration efforts. However, certified and experienced divers are welcome to explore the area independently, as long as they respect conservation rules.
