The Galápagos Islands, a volcanic archipelago, are renowned for their unique wildlife and role in Darwin's theory of evolution. Accessibility can be challenging due to the islands' remote location and protected status; many areas require guided tours to minimize environmental impact. While solo travel is possible on inhabited islands like Santa Cruz or San Cristobal, a cruise or organized land-based tour is highly recommended to explore the more remote and diverse islands. There are no significant seasonal restrictions, though the dry season (June-November) tends to have cooler temperatures and rougher seas, while the wet season (December-May) is warmer and calmer. A trip to the Galápagos can be relatively expensive, with costs including flights, park entrance fees (around $100 USD per adult), accommodation, tours, and food; expect to spend at least $3,000-$5,000 USD per person for a week-long trip. A typical visit lasts 5 to 10 days to allow for exploration of several islands and their varied ecosystems.
