Apart from shopping destinations mentioned before, there are many places that nobody should leave Tenerife without seeing. Tenerife is a big island, and it is understandable that you might want to spend all your days lying in its perfect beaches. However, I think no one should leave Tenerife without visiting its capital Santa Cruz and La Laguna. La Laguna, which is the ancient capital of the Canary Islands, was affirmed a World Heritage Site by the UNESCO. Its old city, La Laguna Cathedral, old churches should not be missed out.
