Maomao Arch - Poor Knights Islands
Pelican Rock, just a short boat ride from Playas del Coco, is one of those sites we always recommend for a relaxed afternoon. Don't let the "shallow training site" tag fool you; there's plenty to keep an experienced eye busy, even if you’re only dropping to 8 or 10 metres. We love cruising over the sandy bottom between the two main pinnacles, keeping an eye out for rays - we've spotted a few guitar rays here, which is always a treat, along with stingrays settled into the sand. Peek into the crevices and under ledges formed by the rocks; that's where the morays like to hide. We've seen some beautifully camouflaged hourglass morays peeking out, and the nudibranchs here are surprisingly diverse for a shallow site, often clinging to the rock face. The visibility averages around 10 metres, so it’s not always gin-clear, but it’s usually good enough to appreciate the details, like the delicate triplefins hovering near the rock, or a hand-strapped crab scuttling past. It’s perfect for divers who want to take their time, practice buoyancy, or just enjoy a chill dive without strong currents.
