Cotopaxi is one of the tallest active volcanoes in the world and is located in the Cotopaxi National Park, approximately 50 km from Quito. You can fly into Mariscal Sucre Airport Quito and either rent a car or use public transportation to get to the National Park. If you rent a car, you will start by driving South on the Pan-American Highway E35. Many busses depart from Quito's main bus terminal, Terminal Terrestre, towards Latacunga and the National Park's entrance.
