Hulls Rock - Mafia Island

MagiColor is exactly what it says on the tin, a vivid spot tucked away in Tayrona National Park. We’ve always found this site to be a lively one, even when other spots nearby feel a little subdued. The corals here, particularly the smooth and knobby star corals, are doing well, forming a good structure for all the reef fish. We often see big schools of Spanish grunts and schoolmasters swirling around, thick enough to make you feel like you’re swimming through liquid silver. What we really love about MagiColor is the chance to spot the more unusual characters. Keep your eyes peeled on the sand patches for flat needlefish hovering just below the surface, or a warteye stargazer peeking out, always a fun find. The maximum depth of 18 meters means a nice long bottom time, perfect for photography or just soaking it all in. Visibility averages about 13 meters, which is decent for the area, and it can clear up significantly on a calm day. This site is a great pick for divers who appreciate a dense concentration of fish life and enjoy searching for the smaller, quirkier critters.
