Ewa Pinnacles Reef - Hawaii
Ewa Pinnacles is a nice, straightforward dive off Oahu, usually reached by boat. We’re talking about a gentle series of rocky pinnacles rising from the sandy bottom at about 26 metres. It’s an easy run for newer divers, with generally mild currents. You’ll typically spot plenty of reef fish flitting about, maybe a few green sea turtles cruising by, and if you keep an eye on the blue, the occasional eagle ray might glide past. It's a relaxed morning out, good for getting comfortable underwater or just enjoying a calm swim.
