Today I got a nice postcard from the Canary Islands! The postcard shows multiple views of Teide National Park. It is located on the island of Tenerife. Its main attraction is Mount Teide, which has a peak height of 3, 718 metres and is the highest peak on Spanish soil. It is also the world's largest volcano as measured from its base on the ocean floor. Another volcano located here is the Pico Viejo, with a peak of 3,135 metres. The park is a UNESCO World Heritage Site. Thanks Patricia!
