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.

This unique museum can be found below the ravishing Space Monument. At The Memorial Museum of Cosmonautics there are several exhibitions with different space objects, documents, and art. If you are interested in space and the cosmonauts, you will most certainly not be disappointed.

A stone's throw from Windhoek's Christuskirche is the city's liveliest city park, attracting picnickers and lunch breakers from the surrounding offices. Although no animals have called the park home for decades, it retains its original name from when it served as a public zoo. An elephant column serves as a reminder of the location's past, when it was used as elephant hunting grounds nearly 5 millennia ago.

If you are planning to visit the KL Menara Tower, make sure to drop by the Forest Eco Park right next to the tower, where flora and fauna that are unique to Malaysia's rainforest is represented. On a lucky day, you can observe two different species of monkeys, as well as birds and squirrels. Another exciting part of a trip to the park is the crossing of steep slopes, bridges and ladder sections, so be sure to dress accordingly.
