Dolphin wall - Iron Bottom Sound
We spent a good chunk of our trip exploring the Infinity Bay House Reef. It’s far more than just a convenience dive. For an easy entry, just off the beach in West Bay, it delivers some serious punch. The inner reef, shallow and bright, is a fantastic spot to just cruise, spotting juvenile parrotfish and cheeky Beau Gregories zipping around. We often saw divers getting comfortable here, and it’s perfect for that. Venture a little further, past the turtle grass beds where we've seen stingrays glide by, and the reef really drops off. The wall itself isn’t a grand canyon, but it’s a healthy descent to 16 meters. We’ve had great luck finding Mottled Conger Morays peeking out from crevices, and the Yellowhead Jawfish are a real treat, always hovering just above their sandy burrows. Keep an eye out for the smaller stuff; the Sand Gobies and Saddled Blennies are well worth a closer look if you slow down. Visibility averaged around 18 meters when we were there, which gives you plenty of scope to take it all in. Our pick for a relaxed afternoon dive, no major current to fight, just good diving.
