Isabela Island, Galápagos — The Complete Visitor Guide

A short 15- to 20-minute dinghy ride from Puerto Villamil. It features a narrow lava channel where you can find whitetip reef sharks resting in the shallows, galapagos penguins and marine iguanas basking on the surrounding lava. The cold season (June-November) provides a reliable time for Galápagos penguin sightings. Meanwhile, sea lions are present year-round.

A nearby free snorkeling site accessible by a dock at the edge of Puerto Villamil. Aside from the standard park entrance, no fees or permits are required. Indifferent sea lions, though sometimes curious, swim in the water and perch on the rocks. The diversity of fish is also great. The site may lack the west coast’s dramatic richness of marine wildlife, such as in Elizabeth Bay and Punta Vicente Roca, but its main selling point is its accessibility. It’s perfect as a complementary morning activity.

Isabela’s primary tortoise conservation facility holds around 1,000 tortoises from six different subspecies. Giant tortoises on Isabela don’t belong to a single classification. Each volcano has its own subspecies that evolved independently in isolation, with a distinct shell morphology and size. A visit allows for an in-depth discovery of Isabela’s biological structure. Located within walking distance of central Puerto Villamil, it is best visited in the morning before midday sun.

On the edge of Puerto Villamil is a boardwalk trail that takes visitors through coastal lagoons surrounded by lush mangroves. There are enough flamingos in the lagoons for casual photographers to take clear, picturesque shots. Common stilts, white-cheeked pintails, gallinules, and whimbrels can also be seen in the same area. The morning light is best for picture-taking. Admission is free, aside from the park entrance.

A lava-block wall constructed by prisoners of the Isabela Island penal colony between 1946 and 1959, built and rebuilt as a punishment task, hence the name. Approximately 5 km one way from Puerto Villamil, visitors can come here by bicycle, horse, or on foot along a sandy track. Exploring the site itself takes 15-20 minutes, with the journey through the arid landscape taking up the majority of the experience. This site can be combined with the nearby flamingo lagoon at Pozo Verde and the viewpoint above the wall for a half-day loop.

Isabela’s most challenging and rewarding hike. The trailhead is a 45-minute drive (4WD only) from Puerto Villamil, followed by a 15 km round-trip hike through cloud forest to the rim of Sierra Negra, home to the world’s second-largest volcanic caldera. Fresh basalt flows from the recent 2018 eruption remain visible, while the nearby Chico Volcano viewpoint features active fumaroles. Seven finch species are commonly encountered along the trail, and Galápagos hawks appear near the rim. Most guided hikes take 5-7 hours and require a licensed naturalist guide. Due to the altitude, uneven lava terrain, and changing weather conditions, this hike is not suitable for visitors with limited mobility. Bringing extra water is advised, as the highland climate can still be dehydrating. The best time to visit the Galápagos Islands is generally from December to May.

In the past, whalers, pirates, and early naturalists all used this secluded cove, making it one of the most historic sites in the Galápagos. Charles Darwin himself anchored here in 1835. The walls are marked with the names and dates of visiting ships, with some predating two centuries. Here, blue-footed boobies nest on the slopes, Galápagos hawks patrol the skies, flightless cormorants, Galápagos penguins, Darwin finches and yellow warblers forage among the vegetation. A short trail leads to Darwin Lake, a saltwater crater lake above sea level, while most cruise visits also include a panga ride along the cliffs.

In 1954, the seafloor around Urbina Bay rose by up to six meters in a matter of hours. The evidence is seen in the bleached coral heads sitting just above the waterline. The vivid yellow land iguanas here are noticeably larger than the ones in Santa Cruz. Sea turtles nest on the beach, their habitats undisturbed, unlike those near inhabited islands. Urbina Bay’s dramatic geology and rich ecosystem make it eye-catching even for seasoned Galápagos travelers.

A shallow bay on Isabela’s west coast, reached by panga ride. While passing through the mangrove channels, travelers can encounter Galápagos penguins sitting on mangrove roots, sea turtles surfacing, and rays gliding across the sandy bottom. The isolated bay concentrates wildlife, making it one of Isabela’s richest marine sites. There are no visitor trails, making visits limited to panga rides and snorkeling.

At the northern tip of Isabela is the collapsed remnant of Ecuador Volcano, forming a dramatic cliff face with caves. Punta Vicente Roca is one of the best dive and snorkel sites in the entire Galápagos, where the Cromwell Current brings in cold, nutrient-rich water, making it a favorite feeding ground for various marine wildlife and a great spot for whale watching. Ocean sunfish (Mola mola) can commonly be seen up close. Galápagos sharks patrol the deeper water. Seahorses play in the kelp along the cliff base. The majestic seascape and its underwater life make this a memorable site for travelers.

This northernmost visitor site on Isabela is the flightless cormorants’ primary nesting habitat in the archipelago. The marine iguanas are among the largest in the Galápagos, a reflection of the nutrient-rich waters brought by the Cromwell Current. Punta Albemarle is only accessible through a panga along the cliffs

Moreno Point’s tidal pools are where an abundance of Isabela’s coastal wildlife gathers. Sea turtles, rays, white-tipped reef sharks, and marine iguanas can be seen lounging in the shallows. Visitors can also see flamingos in the nearby inland lagoons. Since the terrain is raw volcanic lava, the surface is uneven. Use of sturdy footwear is strictly advised.
