Palancar Caves - Cozumel

The Rum Runner wreck, found by happy accident, feels a bit like diving a secret. It’s not one of the big names, which is precisely why we love it. Lying on a sandy bottom at 29 meters, this old party boat is surprisingly photogenic, especially when the light filters down through the surface. What makes it special is how untouched it feels. Because it’s not dived constantly, the marine life here is genuinely inquisitive. We’ve seen slender filefish practically pose for photos, and the black coral growing on the hull provides perfect camouflage for tiny masked gobies. Keep an eye out for patrolling barracuda and schools of French grunts swirling around the superstructure. Penetration isn’t really on the cards, but you can explore the open deck and the wheelhouse, imagining the parties that once happened above. Visibility averages around 16 meters, which is decent for the depth, allowing you to appreciate the wreck's full profile. It's a fantastic choice for those looking for a relaxed deep dive on a characterful wreck without the crowds, perfect for advanced divers who appreciate a quiet encounter.
