In the heart of Konak Square stands İzmir's most iconic landmark, the Clock Tower. Erected in 1901 to mark the 25th anniversary of Sultan Abdul Hamid II's reign, the tower has a height of 25 metres and features four floors and an octagonal plan, characterised by a white marble platform and cut stone structures. No visit would be complete without a photograph next to the majestic monument.

See wild little penguins emerge from the ocean and head for their homes in a natural rookery on an after-dark tour. Established by locals to protect the penguin population, the tour lets you get close to the penguins without disturbing their nightly journey. These are wild birds, so penguin numbers and arrival times vary with the life-cycle activity and weather, with larger numbers of 100-125 birds from September to January. You can expect to get very close to a penguin on this tour.

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.
