4-Day Southern Islands: Isla Lobos' Fur Seals

San Cristobal's airport sits at the edge of Puerto Baquerizo Moreno, a five-minute drive from the town center, so this is usually your first taste of the islands rather than a standalone excursion. Sea lions and marine iguanas are known to rest right next to the runway here, an unscripted welcome few airports can match. From the terminal, a short transfer takes you down to the pier for a panga ride out to your ship.

A short crossing from Puerto Baquerizo Moreno on San Cristobal, Isla Lobos takes its name from the sea lion colony that calls it home, and doubles as a seasonal nesting ground for blue-footed boobies. Frigatebirds have begun nesting here in recent years too, and fur seals turn up now and then. The walk covers roughly 850 meters of mixed rocky and sandy trail.

A dry landing among the rocks puts you right at the start of one of the richest walks in the islands. The trail follows dramatic cliffs where blowholes send spray high into the air with every swell, and along the way marine iguanas bask on the black rock. Between December and March, the males here turn a striking red and green for the breeding season. Punta Suarez is the only place on Earth where waved albatrosses nest, and between April and December you'll find the colony in full swing, their courtship displays peaking in October. Blue-footed and Nazca boobies nest along the same stretch of cliff, red-billed tropicbirds circle overhead, and the endemic Espanola mockingbird, famously bold, often comes right up to visitors. Keep an eye out too for the Galapagos hawk and the Galapagos dove working the scrub beside the trail.

A short landing on one of the most beautiful beaches in the islands brings you into a resident colony of Galapagos sea lions, sprawled across the white sand. Between August and November you may also spot pups nursing nearby. This is one of the only places to see the Espanola mockingbird, found nowhere else on Earth and famously unbothered by visitors. After time on the beach, a relaxed snorkel just offshore is a good way to close out the visit, with spotted eagle rays often gliding beneath the surface.

From the landing, a trail leads to a wide, shallow lagoon where Galapagos flamingos wade through the shallows, filtering shrimp from the mud that gives them their color. Continuing over a low rise brings you to Flour Beach, a nesting ground for green sea turtles between December and June. Just offshore, the eroded remains of an old volcanic cone form Devil's Crown, one of the best snorkeling spots in the islands. White-tipped reef sharks and spotted eagle rays are a near-certain sight inside the ring, and on a good day you might also spot hammerhead sharks, sea lions, or a colorful mix of reef fish weaving through the rocks.

One of the few places in the islands where human history takes center stage over wildlife. In 1793, a whaling captain installed a wooden barrel here as an informal mailbox, and the tradition has never stopped: you're welcome to leave a postcard without a stamp, and to sort through what's already inside for anything addressed near your own home to hand-deliver in person. After a wet landing on the sandy beach, a short walk brings you to the barrel. It is one of the most memorable traditions anywhere in the islands.

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.
