The National Park Service charges $100 to each traveler arriving to the Galapagos Islands. The money goes towards conservation services. This fee must be paid in cash at the airport of arrival. Sometimes, but not always, your tour company will include this fee in the cost of your trip. Be sure to check on this before you leave. Upon departing for the U.S., a departure tax of $25.00 from Guayaquil and $48.40 from Quito will be charged.
