Rock and Ray gives you a decent wall dive, sloping down to 23 metres. We’ve seen a good mix of hard and soft corals here, holding plenty of reef fish, sometimes schooling fusiliers. Keep an eye on the blue – the site is named for a reason, and we've occasionally spotted eagle rays gliding past, along with a few reef sharks if you’re lucky. It's a comfortable dive, usually with mild currents, making it a good option for most experience levels looking for a relaxed exploration.
