On the northwestern side of the country, Montecristi is for experienced divers. There are dozens of real shipwrecks from the time of the Spanish armada sunk due to weather and in battle with English and Dutch pirates. Snorkeling is wonderful at the Cayo Siete Hermanos islands.
The infamous pirate Francis Drake used Montecristi as a base for supplying his ships and hiding from the Spanish fleet in the 16th century. He and other pirates attacked countless Spanish ships, looting the treasure and sinking the vessels off the coast of Montecristi. Many of the estimated 150 shipwrecks have been discovered and a number of them are close to shore and at depths shallow enough for the adventure diver.
