Matts Crack - Poor Knights Islands

Piedra Bonita, "Beautiful Rock," lives up to its name. We think this site is a solid choice for a relaxing afternoon dive, especially if you’re staying in Bayahibe. The rock formation itself is the star, a sizable coral and rock structure that drops to around 25 meters. We’ve found the best of it above 20 meters, where the coral growth is densest. Keep an eye out for the smaller stuff – we often spot Peppered Gobies and Roughtail Gobies on the rock face, and Trumpetfish are usually lurking about. While the data mentions sharks and turtles, we’ve seen more Harlequin Bass and schools of small reef fish weaving through the turtlegrass and manatee grass beds nearby. Visibility averages around 12 meters, so it’s a site where you’ll want to get a little closer to appreciate the details. It’s a pretty straightforward dive, good for most experience levels.
