Audio Guide of Swallow Cave

Swallow Cave is located within Guánica State Forest and is open every day from 7:00 a.m. to 5:00 p.m., although visiting during daylight hours is recommended for safety. To access it, enter via the forest’s main road in Guánica; the trail to the cave is moderate and part of the hiking area. More details are available on the official Department of Natural and Environmental Resources website: Guánica State Forest.

Entry to Guánica State Forest, which includes Swallow Cave, is free for Puerto Rico residents and costs $5 per vehicle for non-residents, with additional fees for large groups. There is no extra charge for the cave itself, but consider voluntary donations for maintenance. Check for updates at Discover Puerto Rico.

It is recommended to allow at least 1.5 to 2 hours for the round-trip hike to the cave, plus extra time to explore the interior and observe wildlife. If you are a beginner hiker, plan for a total of 2 to 3 hours including breaks. Bring a watch or app so you do not stay past forest closing time.

Swallow Cave is a protected natural site within Guánica State Forest, designated a UNESCO Biosphere Reserve in 1981 for its exceptional subtropical dry biodiversity. It is important for the conservation of endemic species such as bats and birds, and it reflects Taíno heritage through ancient geological formations. Learn more at the Department of Natural and Environmental Resources website.

The best time is during the dry season from December to April, when the weather is more favorable and there is less rain on the trails. Choose early mornings, around 8:00 a.m., to avoid the midday heat and see more bird activity. Avoid busy weekends if you prefer a quieter visit.

Access to the cave requires navigating an uneven trail with rocky steps and natural terrain, so it is not accessible for wheelchairs or people with severe mobility limitations. Assistance or alternative forest routes for general sightseeing are suggested. Contact the Department of Natural and Environmental Resources at (787) 861-2560 for adapted options.

Nearby, explore the rest of Guánica State Forest with its 16,000 acres of trails and bays such as Ballena Bay. You can also visit Guánica Beach or Fort Caprón in Ponce, about 30 minutes away by car. For itineraries, check Discover Puerto Rico - South.

Bring comfortable shoes, insect repellent, water, and a flashlight for the cave, as the interior is dark and humid; do not forget sunscreen and a hat for the trail. Go in a group for safety and respect the rules: do not leave trash or touch rock formations. Register at the forest entrance and check the weather before you go.
