4-Day Northern Islands: Darwin Bay's Frigatebirds

Most Galapagos itineraries begin here. Baltra's airport is the world's first fully ecological airport, run on solar and wind power and built largely from recycled materials, including old oil pipes repurposed into the terminal structure. Land iguanas, wiped out here by the 1950s and reintroduced through a decades-long breeding program, now number in the hundreds again, some right around the airport grounds. From the terminal, a short bus transfer brings you to the pier for the panga ride out to your ship.

Reachable only by sea, Black Turtle Cove is a mangrove-lined lagoon on Santa Cruz's north shore, protected as a turtle sanctuary. A slow, quiet dinghy ride carries you between four species of mangrove while sea turtles surface for air around the boat, one of the most reliable sightings in the islands. Look down and you'll often see golden and eagle rays moving beneath the hull, and white-tipped reef sharks resting in the shallows.

A stone stairway carved into the cliff climbs to a wide plateau holding one of Genovesa's largest seabird colonies. The trail passes through a small Scalesia forest, home to the short-eared owl, one of the few predators on the island, before reaching cliffside colonies where Nazca and red-footed boobies nest side by side, frigatebirds wheel overhead, and thousands of storm petrels dart in and out of cracks in the lava. A small colony of fur seals sometimes gathers near the landing. Red-footed boobies nest in only a handful of places across the archipelago, and this is one of them.

Darwin Bay sits inside the flooded caldera of Genovesa, and a wet landing on its white coral-sand beach puts you right in the middle of a working seabird colony. Great frigatebirds display along the shore, males inflating scarlet throat pouches to catch a female's eye, and red-footed boobies nest low in the surrounding trees and shrubs, unusual for a booby. Nazca boobies are just as much a fixture here, while blue-footed boobies are a rarer, luckier sighting. Swallow-tailed gulls and red-billed tropicbirds work the cliffs nearby. If you're a confident swimmer, the bay's calm water is a good place to snorkel or kayak afterward, with a chance of white-tipped reef sharks and sea turtles along the rocky shore.

A geology stop first and foremost. A wet landing on a white coral-sand beach leads out onto a pahoehoe lava field that flowed less than a hundred years ago, its surface still holding the ropy, swirled texture it cooled into, a favorite for photographers. Tiny pioneer plants are just beginning to colonize the cracks in the rock. Bring your camera for the landscape rather than your binoculars here.

A panga brings you ashore onto one of the most distinctive beaches in the islands, with sand tinted deep red by its high iron content, with Rabida's rugged cliffs rising behind it. Sea lions are usually stretched out along the shoreline, and it's a good spot to watch for the endemic Galapagos dove working the sand nearby. From the beach, a short trail winds through palo santo forest and cactus scrub, climbing gently to an overlook with sweeping views across the bay, a nice place to pause and take in the color of the landscape before heading back down. If you'd rather stay on the water, snorkeling right off the beach is an easy, relaxed way to spend the visit, with good odds of company from the resident sea lions.

Set on the grounds of the Galapagos National Park Service on Santa Cruz, this station was once home to Lonesome George, the last known tortoise of the Pinta subspecies. A series of interpretive buildings walks you through the conservation science underway across the islands, and the surrounding native vegetation is a good place to look for Darwin's finches going about their business.

The return transfer is straightforward: a panga ride from your ship to the pier, then a short bus ride to Baltra's airport, the world's first fully ecological terminal, run on solar and wind power. Land iguanas, reintroduced here after being wiped out decades ago, are sometimes seen right around the grounds on the way to your flight.
