Coco Reef - Bayahibe & La Romana

Grottes aux Chats is one of those places that sticks with you, even if the name always makes us picture a dive full of feline fish. It’s actually a cavern system, a proper cathedral of rock, dropping to about 33 metres for recreational divers, though techies can push it deeper. We love the dramatic entrance, a wide mouth that opens into a dark chamber. The ambient light fades quickly, and your torch beam really comes alive, picking out the rough texture of the walls. Inside, the topography is the real draw. We’ve drifted past schools of tiny glassfish shimmering in the darker recesses, and found lobsters tucked into every crevice. Keep an eye out for the big pelagics cruising just outside the main opening, often we’ve seen eagle rays glide by, their shadows moving over the coral bommies. It's a fantastic site for anyone who enjoys a bit of overhead environment, comfortable in the dark, and not reliant on colourful corals for their fix. Visibility here averages around 15 metres, which feels just right for the scale of the place, giving it a slightly mysterious atmosphere without being too challenging. Our tip? Try to time your dive for midday, when the sun can pierce the water just enough to create some incredible light shafts near the entrance.
