The Colombian Caribbean is not where most sailors think to look, but San Andrés and Providencia sit about 750 kilometres northwest of the Colombian mainland, closer to Nicaragua than to Cartagena, and the isolation shows in the water. The sea Seven Colours — as locals call the gradated turquoise around Providencia — is genuinely startling, the kind of colour that makes you double-check your polarised lenses.
The inter-island passage between San Andrés and Providencia runs roughly 90 nautical miles north-northeast, and the northeast trades make it a comfortable reach in both directions if you time the return. December through March is the sweet spot: trades are steady at 15–20 knots, seas are manageable at 1. 5–2 metres, and squalls are relatively rare.
Avoid the May–November period; the western Caribbean throws up nasty short-period seas and unpredictable fronts. Day-sail around Providencia using Southwest Bay and Freshwater Bay as overnight anchorages — both offer good holding in sand and reasonable shelter from the trade swell.
Old Providence and Santa Catalina island are linked by a wooden footbridge and the streets feel more Jamaican patois than Colombian Spanish, with reggae drifting from painted wooden bars most evenings.
Chartering logistics take patience. San Andrés is the only realistic charter base, and the fleet is thin — mostly skippered vessels rather than bareboat. Customs and immigration require zarpe paperwork both departing and arriving in Providencia, which the skipper handles, but budget time and a modest fee at each port. Provisioning in San Andrés is adequate: fresh produce, decent rum, limited chandlery.
Providencia has a small supermarket and that is roughly it.
December to February suits intermediate sailors best; complete beginners should book a skippered charter and let someone else manage the clearance paperwork.
