The Gibbes Museum of Art has between 6 and 8 exhibitions every year, including the permanent Charleston Story exhibit. The museum also offers lectures, tours and classes. After its renovation, the museum reopened again in 2016, transforming into an even more vivid cultural hot spot.

Bulgaria’s coastal bunkers, remnants of its WWII alliance with Nazi Germany, are scattered along the Black Sea coast. In Burgas, one bunker sits just off Central Beach, between the Pantheon of the Fallen Antifascists and the Flora Burgas Expo Centre. Another can be found near Lake Atanasovsko, known as the Bunker at the Salt Pans. Once military outposts, these structures now stand as silent reminders of a complex past, with some repurposed into cafes and covered in murals, or left abandoned, offering a glimpse into 20th-century history.

Just an hour's boat trip away from Cartagena lie the magnificent Rosario Islands, which belong to Colombia's only underwater natural park (Rosario and San Bernardo Corals National Natural Park). Abundant marine wildlife (including over 50 species of corals) and some of Colombia's best beaches draw in many in search of relaxation and active pursuits such as snorkelling and diving. Isla Grande is best for kayaking through unique mangrove forests and seeing the phosphorescent plankton light up the waters of a brackish lake at night, while Playa Blanca is Cartagena's most spectacular white-sand beach (also reachable by land). It should be said that the company you choose to tour with has the potential to make or break the experience. Low cost tours can mean multiple intermediate stops en route to your destination, as well as unpleasant surprises such as no transfer back to your hotel. Try and choose a trusted company with consistently good reviews, or opt for a private tour. Mind that seas may be rough at certain times of the year, particularly in December and January, when tours on smaller boats may even become dangerous.
