I was there. Vilaflor, at 1,400 m altitude, is the highest village of Tenerife, situated south the Teide volcano.
Walking on the active Teide was amazing! Its most recent eruption occurred in 1909 from the El Chinyero vent on the northwestern Santiago rift.
The United Nations Committee for Disaster Mitigation designated Teide a Decade Volcano because of its history of destructive eruptions and its proximity to several large towns.
Teide, Pico Viejo and Montaña Blanca form the Central Volcanic Complex of Tenerife.
