Did you know that Cayo Icacos is the largest key in La Cordillera Nature Reserve, a protected marine sanctuary off Puerto Rico’s eastern coast? This uninhabited island paradise, just 1.5 km (0.9 miles) from Fajardo, offers some of the most pristine beaches and clearest waters in the Caribbean. Once a limestone quarry in the 1930s, today it’s a protected natural wonder where visitors can experience untouched beaches, vibrant marine life, and breathtaking views without the crowds of more famous Puerto Rican islands.
Getting to Cayo Icacos & Planning Your Journey
Water taxi approaching the pristine shores of Cayo Icacos
Unlike the more popular islands of Culebra and Vieques, there’s no regular ferry service to Cayo Icacos. Instead, visitors must take a water taxi or join a boat tour from Las Croabas docks in Fajardo. This small detail is crucial – many travelers mistakenly go to the Fajardo Ferry Terminal, which doesn’t offer service to Icacos.
Water Taxi Options
Water taxis depart from Las Croabas docks in Fajardo approximately every 30 minutes, with the journey taking about 15-20 minutes each way. Expect to pay around $50-70 per person for a round trip. The last water taxi typically returns from the island at 5:30 pm, so plan your day accordingly. If you’re traveling during high season (December-April), it’s advisable to book your water taxi in advance.
Catamaran and Tour Options
For a more structured experience, consider booking a catamaran tour or private charter. These typically include snorkeling equipment, food, drinks, and guided exploration of the island and surrounding reefs. While more expensive than water taxis, they provide a hassle-free experience with all amenities included.
Getting to Las Croabas
Las Croabas is located approximately 63 km (39 miles) east of San Juan, about a 1-hour drive. Since public transportation options are limited, renting a car is the most practical way to reach the docks. This also gives you the freedom to explore other attractions in eastern Puerto Rico.
