In addition to being a phenomenal place to spot fauna on hikes and boat rides, the Galápagos Islands are a world-class scuba-diving destination. Unlike popular areas such as the South Pacific and Caribbean, the Galápagos don't have coral reefs, because the water is too cold. They do have a lot of marine life, including manta rays, sea lions, penguins, sea turtles, iguanas, at least five species of sharks, and hundreds of other fish species, many of them endemic to the archipelago. Galápagos cruises generally offer snorkeling or scuba diving; keep in mind that the water is chilly and most people need a wet suit. A handful of boats catering to experienced divers offer cruises that include any of 30 dive sites over the course of a 1 to 2 weeks. Two to four daily dives are complemented with island excursions. All divers must pay the one-time, $100 (£67) national park admission fee and port fees.

The best months for diving are November to April, when seas are calmer and the water is less cold: 18° to 23°C (64°-73° F). However, even then, many dive sites experience strong currents, surges of cold water that can get as low as 10°C (50°F), and visibility that can get as low as 3m (10 ft.), though it averages 6 to 24m (20-79 ft.). Many of the dives are relatively deep. Night dives are prohibited in the Galápagos. Divers need to prove that they are experienced and have been diving recently in order to join trips. They will also need to use a full wet suit, often with hood. Because of the nature of the diving here, I recommend taking a dive boat with Nitrox facilities. If you aren't already Nitrox certified, you can take the course onboard and dive with Nitrox tanks during the trip. Nitrox will allow you increased time below the surface, an important consideration with these predominantly deep dives.

Various ships offer dive cruises to the northern islands that include comfortable accommodations, good food, and creature comforts. The best and most challenging dive spots are located around the archipelago's northern islands, especially Wolf Island and Darwin Island, but because the main attractions are on the southern islands, excursions that combine divers with nondivers tend to stay in the south.

A less-expensive option is to stay on Santa Cruz or on San Cristóbal and take day trips with a local dive operator. Though the best dive spots are too far north to reach on anything other than a liveaboard ship, there are dozens of excellent dive spots within a 20- to 90-minute boat trip from Santa Cruz, including Gordon's Rocks, where schools of hammerhead sharks sometimes congregate. The conditions in the south are also less demanding, and local dive schools offer basic certification and resort dives for novices.

Though the Galápagos has Ecuador's best diving, the Pacific coast also has its share of dive spots, the best of which is around Isla de la Plata, an offshore island about 2 hours by boat from Puerto López. Dubbed the "poor man's Galápagos," Isla de la Plata has many of the same fish, including white-tipped sharks and manta rays, as well as plentiful birdlife. From June to October, dive trips to the island can be complemented with whale-watching.
