Located at the eastern tip of the island of Tenerife, the largest of the Canary Islands, Santa Cruz is a natural cruise destination as over half of its perimeter is shoreline. The beaches are lovely at that, from the yellow sands of Las Teresitas to the black sands of the quieter, clothing-optional Las Gaviotas. There's also plenty to do and see inland, especially if you're here during the spectacular Carnival.
