The islands are a protected area, so visitors should respect the environment and avoid disturbing the coral reefs or littering. Pack light, wear comfortable swimwear, and consider water shoes for walking on rocky shores. While some islands offer luxury accommodations, most are rustic and focused on nature. Wi-Fi and cell service may be limited, so be ready to unplug and enjoy the natural beauty.

The easiest way to reach the Rosario Islands is by boat from Cartagena. Boats depart from the Muelle de la Bodeguita pier daily, with options ranging from budget-friendly shared tours to private speedboats. Booking a tour in advance ensures a smoother experience, as boats can fill up quickly during high season. The ride typically takes 45–60 minutes.

The best time to visit the Rosario Islands is during the dry season, from December to April, when the weather is sunny and the sea is calm. Avoid the rainy season (May to November), as storms can disrupt boat trips and affect underwater visibility. Early morning departures are ideal to make the most of your day and avoid large crowds.

Day trips typically include round-trip boat transportation, meals, and optional activities like snorkeling or a visit to the Oceanario, a small aquarium showcasing the region's marine biodiversity. Some tours stop at Isla del Encanto or Isla Barú, where you can enjoy beachside relaxation and delicious local cuisine. Be sure to choose a reputable operator for a safe and enjoyable trip, and don’t forget your camera to capture the breathtaking scenery!
