The Galapagos have been declared a World heritage Site by UNESCO and 90 percent of the land area and 100 percent of the surrounding ocean are now part of the Galapagos National Park. Within the area of the park there are some 45 landing sites, each with defined trails, so the impact of visitors to this fragile environment is minimized and the park preserved for futures generations. Each of the landing sites has been carefully chosen to show the different flora and fauna, and with the high level of endemism nearly every trail has flora and fauna that can be seen nowhere else in the world. The total lack of fear exhibited by the birds and reptiles that inhabit the islands enables visitors and scientists a unique opportunity to see and study nature. Never miss the opportunity to go snorkeling when visiting. There is plenty of underwater life to see, including rays, turtles, sharks and many fish.
