Rosario Islands Day Trip from Cartagena: Worth It?

A Rosario Islands day trip is basically a full day on the water: 45-minute speedboat ride out, stops at a couple of small islands for swimming and snorkeling, lunch at a beach club, and a few hours of beach time before heading back. The water is usually clear and turquoise, the reefs are decent for snorkeling (bring or rent gear), and the vibe is relaxed but not deserted—expect other boats and day-trippers. It’s a solid escape from Cartagena’s heat and crowds, but it’s a touristic experience, not a private paradise.

Best time is December to March when the water is calmest and visibility is highest. June–November can be choppier with more rain, though crowds are smaller. Expect to pay around $70–$130 per person for a full-day shared tour including boat, lunch, and basic snorkel stops. Private or smaller-group options push toward the higher end.

Smart pick: choose a tour that includes lunch at a beach club on one of the quieter islands and has at least two snorkel stops. Skip the overcrowded “party boat” versions if you want any peace. Bring reef-safe sunscreen, cash for extras, and don’t expect to see many fish if you go on a weekend in high season.
