Santiago Overview

North Islands
Santiago Island, cradled within the mesmerizing Galapagos Archipelago, emerges as a destination of extraordinary appeal, renowned for its compelling historical significance, diverse wildlife, and breathtaking volcanic landscapes. Encompassing roughly 585 square kilometers, it claims the title of the fourth largest island in the archipelago, and its terrain soars to a notable maximum altitude of 907 meters. This island's rich tapestry of ecosystems ranges from lush mangrove forests to rugged lava fields, creating habitats for an array of unique species, both terrestrial and marine. Santiago Island is a haven for naturalists and adventurers alike, offering opportunities to witness the famed Galapagos tortoises, sea lions, and a plethora of bird species, including the magnificent Galapagos hawk and the playful fur seals. The island's intricate coastline features a mix of sandy beaches and rocky shores, where visitors can engage in snorkeling to explore the vibrant underwater world. Santiago's intriguing human history, which includes remnants of past salt mining endeavors and a history of piracy, adds an additional layer of allure to its natural wonders. The blend of its historical footprints and natural splendor makes Santiago Island a quintessential stop for those seeking to immerse themselves in the unique magic of the Galapagos.

Geological Marvel

The island, originally known as San Marcos, and later James Island, is a geological wonder formed from two overlapping shield volcanoes. The diverse terrain features a vast array of volcanic phenomena, including the majestic basaltic lava flows at Sullivan Bay, which offer a unique glimpse into the island’s volcanic past. The interaction of hot lava with water has led to the formation of striking tuff cones on the eastern and western sides of the island.

A Haven for Wildlife

Santiago Island is a sanctuary for numerous endemic species. Visitors can encounter the Galapagos Fur Seal, Marine Iguana, Sally Lightfoot Crab, Bottlenose Dolphin, and the unique Rice Rat. The island's beaches serve as crucial nesting sites for the Green Sea Turtle, and its rocky grottos are home to a plethora of marine life. Notably, the reintroduction of the Galapagos Land Iguana in 2019 marked a significant step in the restoration of the island’s ecological balance.

Historical Significance

The island's history is as rich as its natural wonders. It served as a resupply base for ancient pirates and was one of the first islands visited by Charles Darwin in 1835, significantly contributing to his evolutionary theories. The exploitation of natural resources by companies and colonizers in the past led to substantial ecological changes, influencing conservation efforts today.

Visitor Experience

Santiago Island offers a multitude of visitor sites, each with its unique appeal. James Bay, with its fur seal grottoes and salt mine crater, and Sullivan Bay, renowned for its lava fields, provide unparalleled opportunities for exploration and wildlife observation. The small island of Chinese Hat, located near Santiago, is a prime spot for snorkeling and observing geological formations.

Conservation Efforts

The eradication of introduced species like goats, pigs, and donkeys has been a pivotal aspect of the island’s conservation strategy. These efforts have led to the restoration of native vegetation and the resurgence of endemic species like the Galapagos Rail and the Santiago Rice Rat.

Marine Life and Dive Sites

Santiago's coastal waters are a diver's paradise. With seven distinct marine dive sites, the island offers encounters with sea lions, fur seals, sea turtles, rays, sharks, and a variety of fish in spectacular underwater settings.

Key Visitor Information

Accessibility to Santiago Island is primarily via cruises, with several tours operating from nearby islands. The island's diverse terrain requires careful planning and appropriate gear for exploration.


Santiago Island stands as a testament to the Galapagos Archipelago's extraordinary natural history and conservation efforts.
