A Rosario Islands day trip is the one experience almost every visitor to Cartagena puts on their list. The Islas del Rosario are a chain of small coral islands inside a protected national park, roughly an hour by boat from the city. Turquoise water, snorkeling, white-sand beaches and fresh fish lunches — it’s the Caribbean postcard you came for.
The big decision is how to go. Most travelers choose between renting a private boat or joining a shared island tour. Both are great — they just suit different travelers.
Option 1: Private boat rental
With a private boat you get the boat and captain to yourself and your group for the day. You set the pace, choose the stops and head back when you’re ready.
Best for: couples celebrating something special, families, friend groups and anyone who values flexibility and privacy.
- Build your own itinerary — beach clubs, quiet sandbars, snorkel spots or Playa Blanca on Barú.
- Bring your own music, drinks and snacks (check what’s included).
- Split between a group, the cost per person can be surprisingly reasonable.
Our pick for private boats in Cartagena is Botegena.
Option 2: Shared island tour
On a shared tour you join other travelers on a set route, usually with stops at one or two islands, time to swim or snorkel, and lunch.
Best for: solo travelers, budget-conscious visitors and anyone who enjoys meeting people.
- Lower price per person.
- No planning — the day is organized for you.
- A social, easygoing day on the water.

Tips for any Rosario Islands day trip
- Leave early. The sea is usually calmer in the morning.
- Ask about fees. A dock tax and national park fee are often charged separately.
- Protect the reef. Use reef-safe sunscreen and never stand on coral.
- Bring cash for snacks, drinks and tips.
- Prone to seasickness? Sit toward the back of the boat.
