Mitsubishi G3M ’Nell’ (Wreck) - Iron Bottom Sound
Porto Mari is one of those spots we always point people towards when they ask about easy shore diving in Curaçao. It’s a double-reef system, which means you’ve got options. The first reef starts pretty shallow, a nice coral patch close to the beach, perfect for snorkelers or a relaxed second dive. Beyond that, a sandy valley leads to the second reef, where we’ve often found things get a little more interesting. We love Porto Mari for its reliable cast of characters. You’ll spot plenty of snappers weaving through the Lettuce Coral, and we’ve had good luck seeing Molly Millers and Candy Basslets darting between the crevices. The maximum depth of 19 metres keeps it comfortable for most certifications. Our favourite tip for Porto Mari: go early. Beat the beach crowds and you’ll often find the reef feels more alive, the light hitting the coral just right, and maybe even a nurse shark still cruising the sandy channels before the day gets too busy.
