Rosario Islands Boat Tour from Cartagena: Worth It?

A full-day Rosario Islands boat tour typically runs 8am to around 4:30pm and includes a stop at Bocachica Fort, a couple of hours at a beach in the islands, snorkeling or swimming stops, and lunch. The boats carry 10–30 people and the ride out takes about 45–90 minutes each way depending on sea conditions and boat size. Expect clear water, decent snorkeling (better if you go early in the day before the wind picks up), and a lot of time spent floating or lounging. It’s not a remote wilderness experience — these islands see plenty of day-trippers — but it’s still the easiest way to get a taste of Caribbean water without renting a private boat.

Best time is December to March when seas are calmer and rain is rare. July–November can be choppier with more afternoon showers. Expect to pay around $80–$160 per person for a standard group tour that includes lunch, snorkel gear, and hotel pickup. Private charters start well over $800 for the boat. Skip the big party boats if you want any peace and quiet; go for a smaller tour that emphasizes snorkeling and has fewer stops. Bring reef-safe sunscreen, a hat, and cash for drinks — the included lunch is usually decent grilled fish or chicken but nothing special.
