The mangrove tunnels of nearby La Boquilla are an easy day trip from Cartagena. Guided tours will often combine a visit to the beach (one of the Playas De La Boquilla) with a boat or canoe tour of the mangroves, passing through Cienaga de Juan Polo and the Cienaga de la Virgen lagoons. Some tours will also include a closer encounter with local fishermen and offer insight into their craft. La Boquilla is an area of contrasts: the district of upscale hotels — Morros — borders on humble neighbourhoods populated by workers. When sitting down to tuck into no-frills seafood dishes served up by local eateries, make sure you're clear about the price of each item ordered from the get-go, as there have been reports of "surprise" bills amounting to several hundred US dollars.

Take a romantic walk along the well-preserved wooden houses in what previously was the largest workers' district in Tampere, built on a sand ridge shaped by the ice age. The area's famous landmark is the Shot Tower, and Rajaportti Sauna, Finland's oldest public sauna, is also found here.

One of the most colourful streets of Funchal, Santa Maria street is a loving art project of local artists. Over 200 doors are plastered with eye-popping paintings of all kinds. Walk down this narrow cobbled street and perhaps take a break in one of the many rustic restaurants and cafes.
