Diving on the islands of Socorro is possible from November to May. You can get there in 24 hours, but the long road is worth it. There you can swim with Pacific manta rays, dolphins, as well as with 10 species of sharks, including whale sharks and schools of hammerhead sharks. If this is not enough for you, then from January to April you can catch humpback whales migrating to the Socorro Islands.
