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.
