Jax Dax - Grand Cayman

Matapaua Bay, nestled within the wider Goat Island marine reserve, is a site we often head to when we’re looking for a relaxed dive that still delivers. It’s pretty shallow, topping out around 12 meters, making it ideal for newer divers or those just wanting to stretch their fins. You’ll find the main sandy bay framed by rocky reefs on either side, cloaked in that classic New Zealand kelp. We love Matapaua for its surprising interactions. Sure, you’ll see the usual spotties and demoiselles zipping about, but keep an eye out for the crested blennies peeking from crevices. We’ve had some fantastic encounters with snapper here, often quite curious, and the red rock lobsters are always a treat to spot tucked under ledges. Our favourite tip for Matapaua: head out on a calm day after a dry spell. Rain and southeast winds can really churn up the silt, dropping that 7-meter average visibility right down. During summer, watch for boat traffic in the main bay; it can get busy. We usually stick to the reef edges early in the morning to avoid the crowds and catch the marine life at its most active. You’re likely to see something unexpected, even if it’s just a lone greenbone cruising by.
