4. Puerto Ayora, Galapagos
While strong currents generally make the Galapagos unsuitable for beginners, more adventurous and experienced divers will be able to freely swim with hammerheads and a variety of other sharks. The Galapagos Islands themselves are home to some of the world’s most fascinating wildlife too, with many species being endemic to the region. Whitetip reef sharks, nurse sharks and Galapagos sharks are prevalent in these prolific waters. Don’t worry, there have only been 6 recorded shark incidents these since 1854. There’s so many other food sources in the area, they don’t bother munching on the tourists. Check Scuba Iguana for top-notch Galapagos dive trips.
