    Tunel Azul offers an interesting cave dive just off Varadero. We’ve found the entry to be straightforward, leading into a series of interconnected chambers and swim-throughs. You’ll navigate through some tight spots, so good buoyancy control is key. It’s a solid pick for divers looking to explore something a bit different than the usual reef, particularly those with some experience in overhead environments.
