Heron Island - Coral Sea

Los Buzos is a real standout for us in Santa Marta, especially on a calm day. You’re essentially diving two submerged islands, peaking at about 8 meters, with a channel between them. We love dropping down the wall face on one side, which goes beyond our max 18m, or exploring the gentler slopes. Visibility usually hits 15m, sometimes more, letting you really appreciate the Massive Starlet and Lettuce Corals that dominate the reef. Keep an eye out for Black Hamlets darting around and the shy Key Brotula tucked into crevices. We’ve had some fantastic encounters here with schools of French Grunts and Parrotfish – those Greenblotch ones are particularly striking. It’s a comfortable dive, perfect for photographers or anyone who just wants to drift and soak in the healthy coral formations and abundant reef fish. With a bit of luck, a Yellow Stingray might glide past, or even one of those vibrant blue tangs.
