Devil’s Crown is an islet with an eroded volcanic cone close to Punta Cormorant and is one of the most interesting underwater sites in Galapagos. Some experience is recommended--at least for free diving.
Divers and snorkelers can expect to see a wide range of brightly coloured reef fishes and hammerhead sharks, both within the “crown” and outside. Inside, you will see smaller fish such as parrotfish, and outside, larger fish such as palometas.
There are underwater caves between these two areas, but beware: the currents are strong and hammerhead sharks frequently travel through them.
