Galapagos is perhaps the planet's ultimate ecological travel destination with fearless wildlife and fascinating ecology everywhere you look. Nearly every trip to Galapagos can be considered an eco-tour as it is one of the most highly protected and regulated eco-travel destinations in the world with strict limits on the number of yachts, the maximum capacity of yachts (100 guests), strictly coordinated itineraries to avoid overcrowding or overuse of National Park visitor's spots, the requirement to always be with a guide, and a maximum group size of 16 guests per guide. Extraordinary efforts are made to maintain the ecological integrity of the Galapagos including prevention and eradication of invasive species, strict leave no trace tourism regulations, and scientific research coordinated by the Charles Darwin Foundation.
