Teide National Park, a World Heritage Site with over three million visitors a year, is the best place to see volcanic phenomena in Tenerife. You’ll be astounded by the colours and the wild force of this surreal landscape, overlooked by Spain’s highest peak at 3,718 metres. It is home to many local species of flora and fauna, such as the Teide violet or the Tenerife bugloss, whose bright colours stand in stark contrast to the thousands of tonnes of ochre running through this unique landscape.

Located on the South Bank, right next to London Eye, SEA LIFE London Aquarium harbours one of Europe’s largest collections of global marine life covering more than 500 species, 14 themed areas and two million litres of water. The exhibition includes favourites such as seahorses, octopuses, zebra sharks and clownfish. There are also interactive experiences, so you can see diving displays, watch the sharks being fed, or even try and feed the stingrays yourself. And don't forget to take a dive 'under the ocean' in the glass tunnel walkway.

Set on a natural cove, the Varadero Delfinario invites visitors to see the graceful marine mammals up close and even - if they so desire - go for a swim in their company, all at a rather moderate fee. Dolphins are kept in a favourable natural environment of a sea inlet.
