5-Day Southern & Western: Kicker Rock's Swim Channel

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.

Rising nearly 148 meters straight out of the Pacific, split by a channel narrow enough to swim or boat through, Kicker Rock is the most dramatic silhouette in the islands. Blue-footed boobies, frigatebirds, and sea lions are often seen around the rock face, and below the surface this ranks among the best diving and snorkeling in Galapagos, with hammerhead and Galapagos sharks a real possibility in the channel.

Formed by geological uplift rather than volcanic activity, Santa Fe is unusually flat for a Galapagos island, and it's the only place on Earth with its own endemic subspecies of land iguana. After landing in clear, turquoise water, a walk through a forest of giant, tree-sized Opuntia cactus leads to iguanas basking beneath them. The Galapagos dove is a reliable sight along the trail, and with some luck you may also spot the Galapagos snake or the Galapagos hawk.

A wooden staircase of 372 steps climbs Bartolome's extinct volcano from a lava-and-concrete dock or sandy beach, depending on conditions. Along the way, red, orange, black, and even green volcanic layers mark the slopes, home to pioneer plants like the island-endemic Tiquilia nesiotica, lava cactus, and scattered Scalesia. With some luck, a lava lizard crosses the trail. At the top, the view over the twin bays and the iconic Pinnacle Rock is the reward for the climb. Back at sea level, a snorkel around the coral reef and submerged lava rocks is a good bet for Galapagos penguins and white-tipped reef sharks, with sea turtles and manta rays turning up now and then too.

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.

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.
