The Rosario Islands They’re the perfect getaway from Cartagena: turquoise waters, coral reefs, and an island vibe less than an hour away by speedboat. Most boats depart from the Muelle de la Bodeguita between 8:00 and 9:00 a.m., and the trip takes 45 to 60 minutes depending on the weather. If you’re going on your own, make sure to confirm the return trip in the afternoon.
The archipelago belongs to the Parque Nacional Natural Corales del Rosario y de San Bernardo, a fragile marine ecosystem. Swim without touching the coral, don’t feed wildlife, and choose authorized guides.
What can you do in a day? Start with snorkeling in shallow reefs or a kayak outing through the mangroves. on Isla grande you can also add walks, inland lagoons, and if you stay overnight, see bioluminescent plankton at night.
If you’re traveling with kids or interested in marine life, the Oceanario de San Martín de Pajarales is a classic stop. It’s open daily from 9:00 a.m. to 1:30 p.m. and offers educational exhibits. Plan your visit in the morning to avoid the heat.
Practical tips: bring cash (many islands don’t have ATMs and many places don’t accept cards), reef-safe biodegradable sunscreena hat, and water. Make sure your tour operator is authorized , and ask about environmental fees and what stops are included before you board.

Suggested itinerary: depart early from Cartagena, make your first snorkeling stop, then head to a beach club for lunch and downtime. After that, visit the oceanarium or go kayaking, and return mid-afternoon. If you can stay one night on Isla grandeyou’ll enjoy quieter beaches and the magical glow of the bioluminescent sea at night.
