8-Day Western & Southern: Tagus Cove's Sailor Graffiti

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.

Also known as Witch Hill, Cerro Brujo greets you with towering cliffs before the dinghy even reaches the beach. Once ashore, you can relax alongside the sea lions, snorkel straight from the sand, or walk to a hidden lagoon where shorebirds work the shallows. Blue-footed boobies, swallow-tailed gulls, and marine iguanas are often somewhere along the shoreline and cliffs too.

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.

Puerto Egas stands out for its black volcanic sand and a shoreline where land and sea meet in close quarters. Galapagos hawks are often seen along the walk, and at the far end waits a colony of Galapagos fur seals tucked into shaded rock grottoes, one of the more reliable places in the islands to see this endangered species.

Fernandina is the only major island in the archipelago with no introduced species, which makes Punta Espinosa one of the most pristine wildlife encounters anywhere in the Galapagos. A wet landing brings you onto black lava draped with the largest gathering of marine iguanas in the islands, alongside Galapagos penguins and flightless cormorants, both drawn here by the cold, nutrient-rich current. Around June, when marine iguana hatchlings emerge, keep an eye out for the Galapagos racer snake hunting along the nesting zone. Snorkeling here is a rare chance to watch marine iguanas feeding underwater, a behavior found almost nowhere else.

A zodiac ride along Tagus Cove's cliffs is the first stop, tracing walls carved with the graffiti of sailors and whalers going back over a century. Charles Darwin himself anchored here in 1835. Watch the rock for Galapagos penguins and flightless cormorants before you land and set off on a gently climbing trail, roughly 30 minutes each way, to a viewpoint over Darwin Lake, a crater lake saltier than the ocean itself. Along the way, look for land birds that are easy to miss: ground and tree finches, yellow warblers, large-billed flycatchers, and, with a little luck, the tool-using woodpecker finch. Land iguanas and giant tortoises sometimes cross the path as well. Back at the water, most visits close with a dinghy ride or a snorkel along the submerged cliff wall, depending on the day's plan, with another good chance at penguins and cormorants gliding by.

At the base of Alcedo Volcano on Isabela, Urbina Bay marks a dramatic geological event: a 1954 uplift left blocks of coral fully exposed on dry land, well above the waterline. A long, level walk leads out to them, passing land iguanas and flightless cormorants along the way, and, on occasion, a giant tortoise.

At first glance Punta Moreno looks like little more than a lava flow at the base of Cerro Azul, but its black surface holds a series of lagoons with a surprising amount of life. Flamingos are a fairly good bet in the pools, and paint-billed crakes, white-cheeked pintails, and common gallinules turn up for those willing to watch the water closely.

A dry landing sets you down on North Seymour's flat, sun-baked terrain, and the trail wastes no time getting to the action: magnificent frigatebirds display from low shrubs right along the path, males inflating their scarlet throat pouches into balloons to catch a female's eye. Blue-footed boobies are a near-constant presence along the same stretch, and during the breeding season you may catch their high-stepping courtship dance just a few feet from the trail, showing off the bright blue feet that give the species its name. Land and marine iguanas share the coastline as the trail loops back toward the water, and sea lions haul out along the shore. Keep an eye on the cliffs above the surf too, where swallow-tailed gulls sometimes perch between flights out to sea.

A short landing puts you immediately among sea lions and the endemic Plaza land iguana, smaller and more golden than its relatives elsewhere. Watch closely and you might spot a rare hybrid, the result of an occasional cross between a marine and a land iguana found only here. The trail crosses a carpet of succulent Sesuvium, red for part of the year, studded with Opuntia cactus. Along the cliffs, swallow-tailed gulls nest on the ledges beside red-billed tropicbirds, and frigatebirds circle overhead as the loop returns to the landing.

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.

A scenic lookout point on Floreana overlooking the water below, where brown pelicans, red-footed boobies, magnificent frigatebirds, and the diminutive Elliot's storm-petrel are often seen over the surrounding cliffs and sea.

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.

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.

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 Galapagos National Park's Interpretation Center on San Cristobal, open since 1998, walks you through the islands' volcanic origins, the evolution of their wildlife, and the conservation work protecting them today, organized chronologically across a series of exhibits. It's a good first stop for context that makes everything you see afterward click into place, a walk-through, education-focused visit rather than a wildlife stop.

The transfer back is the reverse of the arrival: a panga ride from your ship to the pier in Puerto Baquerizo Moreno, then a short drive to the airport, which sits right next to town. Keep an eye out for sea lions and marine iguanas near the runway on the way in, one last sighting before you fly out.
