The Complete Galápagos Travel Guide: Isabela Island
From active volcanoes and giant tortoises to penguins, sea turtles, and lava-carved coastlines, the Galápagos’ largest island is also its wildest
Isabela Island is the largest island in the Galápagos and the archipelago’s wildest inhabited destination. Home to six volcanoes, vast lava fields, white-sand beaches, and abundant wildlife, it offers a more remote and adventurous experience than the other populated islands. Marine iguanas, giant tortoises, Galápagos penguins, flamingos, and sea turtles can all be found here, often just minutes from the island’s only town, Puerto Villamil.
Despite its size, Isabela remains remarkably undeveloped. Puerto Villamil is a laid-back coastal town with sandy streets, beachfront restaurants serving tasty Ecuadorian cuisine, and easy access to the island’s top attractions. Whether you’re planning a day trip or a longer island-hopping adventure, this guide covers everything you need to know about visiting Isabela Island, including transportation, activities, wildlife, and practical tips. And if you’re interested in a luxury Galápagos trip to Isabela, we can arrange that too.

Isabela Island Galápagos: Fast Facts
Isabela is the largest Galápagos island, shaped like a seahorse and home to six volcanoes. It sits in the western archipelago, about 621 miles (1,000 km) off mainland Ecuador, and is home to more wild giant tortoises than anywhere else on Earth (estimated between 12,000 and 15,000 individuals).
- Location: Isabela is situated in the western part of the Galápagos, about 620 miles (1,000 km) off the coast of mainland Ecuador. Its volcanic terrain and unique flora and fauna were formed by the confluence of three tectonic plates.
- Size: As the largest island in the Galapagos, Isabela spans 1,770 square miles (4,588 sq km), encompassing diverse ecosystems of volcanic landscapes, lush highlands, and unspoiled beaches.
- Population: Isabela Island is home to approximately 2,000 residents, making it the second-smallest population among the islands. Floreana is number one, with a mere 160 or so residents.
- Main Town: Puerto Villamil serves as Isabela’s main town, a charming coastal village with epic ocean views and a relaxed atmosphere.
- Economy: Isabela’s economy thrives on tourism and fishing, attracting visitors worldwide due to its awe-inspiring landscapes and abundant wildlife. Sustainable fishing supports the local community.
- Conservation: Much like the rest of the archipelago, Isabela Island showcases exemplary conservation efforts. Collaborative initiatives between organizations and the local community protect its unique biodiversity and fragile ecosystems. Measures include invasive species control and sustainable tourism practices.
- Wildlife: Encounter iconic Galápagos species like giant tortoises, marine iguanas, flightless cormorants, and Galápagos penguins, as well as diverse marine species found nowhere else on Earth.
- Natural Wonders: From the majestic Sierra Negra volcano, with its breathtaking panoramas and expansive lava fields at Volcán Chico, to the enchanting Los Túneles, whose collapsed lava tubes make ideal snorkeling spots, Isabela is filled with wonders. Don’t miss the wide and inviting beaches of Puerto Villamil, located near the Tortoise Breeding Center, which are a perfect place to relax after a long day exploring.
- Getting Around: Exploring Puerto Villamil is primarily done on foot or by bicycle, given the town’s small size. Taxis are available for longer distances, while guided tours and small boat rentals allow visitors to experience the island’s natural wonders. (Insider tip: rent a bicycle on day one of your trip. You’ll cover more ground than you think—Wall of Tears, the wetlands, and Concha Perla are all reachable in a single morning, and you’ll avoid the heat by being back in town by lunch).

Isabela Island Galápagos: Getting There
To reach Isabela Island, you have two options. Choose a swift inter-island flight from Baltra Airport to Isabela’s airport in Puerto Villamil, or, upon arriving at Baltra Island, embark on a short ferry ride across the Itabaca Channel to Santa Cruz Island. From there, you can continue the journey with a scenic two-hour speedboat ride through the Galápagos marine reserve, which connects Puerto Ayora on Santa Cruz to Puerto Villamil on Isabela.
Insider tip: Those who opt for the boat should take a seasickness tablet beforehand, as the ocean can get bumpy at times, particularly from June to December.
Isabela Island Galápagos: The Volcanoes
Isabela was formed by six shield volcanoes that grew and eventually merged: Alcedo, Cerro Azul, Darwin, Ecuador, Sierra Negra, and Wolf. Five remain active, making Isabela one of the most volcanically active places on Earth. Wolf Volcano is the highest point in the Galápagos at 5,600 feet (1,707 m), but there are other volcanic highlights on Isabela: lava flows running into the sea, the vast Sierra Negra caldera, and flamingo lagoons fed by brackish water trapped behind the dunes.
This volcanic activity is exactly why Isabela’s wildlife is so distinct. The island’s six volcanoes were isolated from one another by lava fields for so long that giant tortoises evolved into separate subspecies on different slopes. It’s possible to see all five native species on a visit to Isabela.
Isabela Island Galápagos: Things to Do
There’s no shortage of things to do on Isabela Island, from snorkeling around submerged lava tunnels to hiking up volcanoes.

The Wall of Tears
The Wall of Tears is a 330-foot (100 m) stone wall located 3.7 miles (6 km) west of Puerto Villamil. Built by prisoners of the former penal colony between 1945 and 1959, it stands as one of the Galápagos’ most significant historical sites. The wall can be reached by bicycle or on foot via a scenic coastal trail. Fun fact: according to local legend, if you stand near the wall at dusk you can hear echoes of the wailing prisoners who perished there.
Flamingo Lagoon
Located on the edge of Puerto Villamil, Flamingo Lagoon is one of the best places on Isabela to see Galápagos flamingos in the wild. The shallow lagoon also attracts other waterbirds and shorebirds, making it a popular spot for wildlife viewing, particularly during the early morning hours.
