Canary Islands

The Canary Islands, a Spanish archipelago off the coast of northwestern Africa, are rugged volcanic isles known for their black- and white-sand beaches. Tenerife, the largest island, is dominated by the sometimes-snowy active volcano Mt. Teide, which has its own astronomical observatory and is part of Teide National Park. Tenerife hosts a huge pre-Lent Carnival in the capital, Santa Cruz de Tenerife. ― Google
