Audio Guide of Culebra National Wildlife Refuge

Culebra National Wildlife Refuge is open 24 hours a day, but visiting during daylight hours is recommended for safety. To get there, take a ferry from the Ceiba or Fajardo terminal (schedules vary; check Puerto Rico Ferry), or a short flight from San Juan Airport to Culebra. The phone number for the Department of Natural and Environmental Resources (DRNA) is (787) 724-8774 for more details.

Admission to the refuge is free, as it is a protected area managed by Puerto Rico’s DRNA. However, the ferry from the mainland costs about $3 one way and $5 return per person, and vehicles have additional fees. For updated information, visit the official DRNA website.

A typical visit lasts 4 to 6 hours, depending on whether you explore beaches such as Flamenco Beach or trails on Culebrita. If you include snorkeling or hiking, it could extend to a full day. Plan according to your itinerary so you do not feel rushed and can fully enjoy nature.

Culebra National Wildlife Refuge, established in 1962, protects unique ecosystems such as mangroves, unspoiled beaches, and sea turtle habitats, along with a rich historical heritage that includes World War II sites used by the U.S. military. Its significance lies in conserving biodiversity on a largely untouched island in Puerto Rico, while promoting environmental education and ecotourism.

The best time is during the dry season from December to April, with less rain and calm waters ideal for snorkeling. Visit early in the morning to avoid crowds and enjoy sunrise on beaches such as Flamenco Beach. Avoid hurricane season from June to November.

Some areas, such as Flamenco Beach, have paved paths and adapted access, but much of the refuge includes uneven terrain and sandy beaches that can be challenging. It is recommended to contact the DRNA at (787) 724-8774 for specific options or assistance, and consider guided visits if needed.

Nearby on the island of Culebra, visit Zoni Beach for more snorkeling or Culebra Lagoon for birdwatching. On the mainland, explore El Yunque National Forest about an hour away by ferry from Fajardo. For more ideas, check guides at Discover Puerto Rico.

Bring insect repellent, sunscreen, water, and comfortable shoes for the trails; follow leave-no-trace principles to help preserve the environment. Book the ferry in advance and consider renting a jeep to get around the island. If you go snorkeling, use your own gear or rent it in Culebra to reduce impacts on the coral reefs.
