There are 39 volcanoes in Ecuador. They are fascinating to climb. Give yourself time to adjust and acclimate before venturing on a potentially taxing trip. The extinct volcano Imbabura, not far from Otavalo, is a great day hike if you start early. For guidelines on approaching any area you choose to climb, pick up a hiking guide for Ecuador or locate the place in a tourbook.
Ecuadorian cuisine is fantastic.
If you like seafood, you will find it unparalleled in the coastal towns. Cuy is guinea pig, which usually comes roasted. Try it depending on how brave you feel and the strength of your stomach. Llampingachos are a fantastic hot food - they are hot cakes composed of potato, cheese, and achiote. Try some of the different fruits and juices.
