snorkeling & scuba diving
Snorkeling and diving are very popular activities as the sea life is so rich and colourful.
Snorkeling equipment should be available from your tour operator but check first if you don't have your own. You may also want to bring a waterproof camera. Remember to wear at least a T-shirt and suntan lotion if you are snorkeling, as it's all too easy to get sunburnt in the strong sun. Snorkeling offers a way to be in the water with fish, sea turtles, sea lions, and other creatures and is a great option for those who don't have scuba certification. The islands that are older further to the west often have cold temperatures. Wetsuits can be rented at the same locations as snorkeling equipment.
Diving in the Galapagos is incredible as noted by Rodale's Scuba Diving Magazine. Darwin and Wolf Islands have been ranked as the best dive destination in the world for several years in the categories of healthiest marine environment, best big animal dive and best advanced diving. That said, the Galapagos is not necessarily the right place for beginners or novices. Currents, surge, cold water, and sometimes poor visibility and depths make this a challenge. Certification courses are available in both Santa Cruz and San Cristobal for those looking to learn, and there are several dive sites that are relatively beginner-friendly.
There are 2 ways to dive in the Galapagos Islands:
Daily dives with a local tour operator from Santa Cruz, Isabela and San Cristobal.
Galapagos liveaboards. Only liveaboards reach Darwin and Wolf. These 2 sites are the reason most divers come to Galapagos.
Two of the world's premier diving destinations, Darwin Island and Wolf Island, are accessible only via live-aboard. These islands present challenging currents and are not suitable for beginners, but offer amazing opportunities to see huge schools of hammerhead sharks, Galapagos sharks, Silky sharks and whale sharks in season July-Nov, in addition to other pelagic life like giant mantas, eagle rays, sting rays, huge schools of jack and tuna, sea turtles, sea lions and more.
Note that park regulations may change unexpectedly; in 2007, many divers were caught unaware as the National Park withdrew diving permits from quite a few cruise ships without notice, leaving many divers without dive cruises they had booked far in advance. For this reason, travelers are advised to get the most up-to-date information possible when planning a dive trip to the Galapagos Islands. As of 2010, the National Park is now regulating land-based diving for the first time and few of the many shops operating have the new permits necessary. It is best to ask if an operator has a dive permit, otherwise you may be turned back by Park Rangers and not permitted to dive. As of 2011, the National Park no longer permits dive liveaboards to offer land visits, except for the Highlands of Santa Cruz which is on all itineraries.
