This morning we explored the easternmost point of San Cristobal Island, one of the driest areas in Galapagos. This contrasts starkly with the westernmost point of this same island — which is the wettest location of the whole archipelago. This is a natural phenomenon that occurs in some of the big islands, creating different conditions for different animals and plants. In some areas of the Galapagos we have thirty inches of rain a year; a different part of the same island may receive less than five inches. The archipelago has up to six different vegetation zones with different animals and plants; this may be the reason why the islands have a high degree of endemism.

National Geographic Endeavour II
Santa Cruz
Our day on Santa Cruz Island began with a visit to the renowned Fausto Llerena Breeding Center, where conservationists are working tirelessly to protect the future of the Galápagos giant tortoises. We observed tiny hatchlings, just months old, steadily making their way through enclosures designed to ensure their survival before being released into the wild. Seeing the various stages of growth—from juveniles to the impressive adult tortoises—gave us a deeper appreciation for the incredible conservation efforts that have helped recover populations once on the brink of extinction. In the afternoon, we ventured into the lush highlands, where we encountered these giants in their natural habitat. Among the misty foliage, we witnessed an extraordinary sight—a rare mating display. A massive male approached a female, stretching his neck and lifting his shell in a show of dominance. His deep, resonant bellows echoed through the forest, an unmistakable sign of courtship. The slow yet deliberate interaction was a reminder of the patience and resilience these creatures embody, having survived on these islands for millions of years. Santa Cruz’s highlands remain one of the best places to observe these magnificent creatures, and our experience today highlighted both their enduring presence and the efforts to ensure their survival for generations to come.
