The sister island, Gozo, is well worth a visit on its own. Hire a car or book one-of-the-day jeep safari trips that are offered by multiple tour operators. Upon disembarking, you'll immediately notice the difference between the islands. Gozo has a more serene atmosphere and is packed with lush farms. While you're here, don't miss the Citadel in Victoria, the Saltpans, the Inland Sea, and the cliff where the Azure Window (formerly one of the most famous landmarks of Malta) once stood before its collapse in early 2017.

More than just a bookstore, Livraria Lello is a historical and architectural masterpiece in downtown Porto. Opened in 1906, Livraria Lello & Irmão as it is also known combines elements of Neo-Gothic, Art Deco, and Art Nouveau styles that comprise intricate woodwork, a large stained glass window bearing the bookshop monogram with the motto "Decus in labore" (dignity at work, in Latin), and a remarkable red spiral staircase, which starts as one set of stairs and splits into two that join in a circular design. The latter is a huge attraction here since it resembles the Grand Staircase from the Harry Potter films, and considering J.K. Rowling was once a Porto resident, there is a high chance this place might have inspired her. Livraria Lello became so popular with tourists that in July 2015 the store started charging a 5 Euro entrance fee and queues can take over an hour. You can purchase tickets on their website.
