Located in a tuff cave, Cimitero Delle Fontanelle, also known as the Valley of Death, is an underground cemetery containing the remnants of more than 15,000 Napolitains. A visit to Fontanelle Cemetery offers a somewhat unique — and possibly morbid — experience.

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.

Not far from Naples, the beautiful town of Amalfi is the perfect spot for a one-day excursion: it boasts a stunning seaside and a surprisingly rich history — it used to hold huge maritime power in the Middle Ages — which has left interesting sights such as the St Andrew Cathedral with its scenic staircase. To explore it fully, consider booking a guided tour.
