Kona - Hawaii

Moon Hole isn't just a sandy patch, it's a calm entry into a really interesting part of Roatán. We often start here for buoyancy work, the 15-meter max depth gives you plenty of room to get comfortable before you even think about the main event. What we really love about Moon Hole is its easy connection to Ron’s Wreck. You cross a short stretch of coral, sometimes spotting a big milk conch or a rusty goby peeking out, and suddenly you’re there. Ron's Wreck itself is more like a scattered collection of historical bits than a full ship. Think old fishing boat, broken apart and now home to all sorts of life. We've seen black and white-spotted morays tucked into crevices, their heads swaying slightly. Keep an eye out for blue parrotfish nibbling at the growth, and if you’re lucky, a turtle might glide past. The wreck is shallow enough that sunlight floods everything, making the coral patches around it glow. It’s a gentle exploration, perfect for divers wanting a relaxed wreck experience without the deep, dark drama.
