Playa de Las Teresitas
Golden sand, imported from the Sahara, stretches for more than a mile at this beach not far from Tenerife’s capital Santa Cruz.

As well as digging sand castles or swimming in the calm waters, you can take part in a game of volleyball, a yoga class, or visit one of the bars and restaurants.
