Culebrita Island day trip
Written By: Captain Alberto Jimenez
As a captain who has navigated Puerto Rico's waters for over two decades, I can confidently say that Culebrita represents the pinnacle of Caribbean beauty in its purest, most untouched form. This tiny, uninhabited island—visible from Culebra's Zoni Beach—beckons visitors with its crystalline waters, pristine beaches, and secrets that only a handful of people discover each day. At Curate Fishing, we've perfected access to this remarkable destination, combining our intimate knowledge of these waters with specialized equipment and local expertise to provide an experience that transcends typical tourist excursions.
What Makes Culebrita Extraordinary
Culebrita Island, measuring just one mile in length and half a mile wide, exists as Puerto Rico's last untouched frontier. Unlike its larger neighbor Culebra, this uninhabited cay remains completely free from commercial development, creating an authentic paradise that feels like stepping into a nature documentary. Part of the Culebra National Wildlife Refuge, the island serves as a sanctuary for endangered species and pristine ecosystems that have thrived undisturbed for generations.
The island's unique Y-shaped geography creates multiple distinct environments within its small footprint. From the moment you approach, the contrast becomes apparent—dramatic rocky outcroppings frame perfect white sand beaches, while crystal-clear waters reveal coral formations and marine life that seem almost too vibrant to be real.
Playa Tortuga: The Crown Jewel
The Most Beautiful Beach You've Never Heard Of
Playa Tortuga, situated on Culebrita's northwest coast, represents everything a Caribbean beach should be. This crescent-shaped cove features powder-soft white sand that feels like walking on silk, framed by turquoise waters so clear you can spot fish swimming from 50 feet away. The beach's name derives from the green sea turtles that call these waters home—during our visits, spotting multiple turtles grazing in the seagrass beds is virtually guaranteed.
Unmatched Snorkeling Experience
The waters surrounding Playa Tortuga offer some of the Caribbean's finest snorkeling. The shallow seagrass beds that attract dozens of green sea turtles create an underwater garden where these gentle giants graze peacefully, often allowing snorkelers to observe them for extended periods. The eastern side of the beach features a small but vibrant coral reef system hosting colorful parrotfish, angelfish, and an occasional southern stingray gliding gracefully through the shallows.
Our specialized approach to Tortuga Beach ensures optimal conditions for underwater exploration. We time our arrivals based on tidal schedules and weather patterns, providing the clearest visibility and calmest conditions for both novice and experienced snorkelers.
The Natural Baths: Nature's Jacuzzi
Las Piscinas Naturales - A Geological Wonder
Just a short walk east from Playa Tortuga lies one of Culebrita's most extraordinary features—the Natural Baths, known locally as "Las Piscinas Naturales." These large tidal pools, carved by centuries of wave action against volcanic rock formations, create natural jacuzzis where the powerful northern swells are tamed into gentle, refreshing pools.
The experience varies dramatically with conditions. During calm weather, these pools become warm, tranquil baths perfect for relaxation. When northern swells arrive, they transform into dynamic, effervescent pools where waves crash over the rocks, creating a natural spa experience unlike anything else in the Caribbean. Small marine creatures often share these pools, adding to the magical experience of bathing alongside hermit crabs and tropical fish.
Safety and Access
Our captains provide detailed guidance on safely accessing and enjoying the Natural Baths. We recommend water shoes or sturdy sandals due to the rocky surfaces, and our guides demonstrate proper entry techniques to maximize enjoyment while ensuring safety.
Culebrita Lighthouse: A Window Into History
The Last Spanish Lighthouse in the Caribbean
Perched atop Culebrita's highest point stands the historic Culebrita Lighthouse, constructed between 1882-1886 during Spanish colonial rule. This remarkable structure represents the only remaining Spanish-era lighthouse in the entire Caribbean, making it both a navigational landmark and a precious historical artifact.
Architectural Marvel and Historical Significance
The lighthouse, officially known as Faro Isla de Culebritas, served as a crucial navigational aid for vessels traversing the Virgin Passage and Vieques Sound for nearly a century, operating continuously from 1886 until 1975. Built to help secure Spain's claim over the Culebra archipelago, it guided countless ships through these treacherous waters during an era when navigation relied entirely on visual landmarks.
The Hike and Panoramic Views
The 20-minute uphill hike to the lighthouse ruins, while challenging in the tropical heat, rewards visitors with breathtaking 360-degree views. From this vantage point, the entire Culebra archipelago spreads below, with the Virgin Islands visible on the eastern horizon and mainland Puerto Rico's mountains forming a dramatic backdrop to the west. The lighthouse itself, despite storm damage and the passage of time, retains its distinctive architecture and marble-tiled floors that speak to its original grandeur.
Current Condition and Conservation
While the lighthouse structure remains fascinating to explore externally, interior access is prohibited due to deteriorated conditions. Hurricane damage over the decades, including the loss of the original green brass dome (which can still be found on the grounds), has left the building in ruins. However, conservation efforts by Para la Naturaleza and the Municipality of Culebra aim to preserve this historic treasure for future generations.
Multiple Beach Experiences
Beyond Playa Tortuga
While Tortuga Beach captures most attention, Culebrita offers several other distinct coastal experiences:
West Beach (Main Landing Area): Where most water taxis dock, this protected cove provides calm waters ideal for less experienced swimmers and serves as the gateway to the island's hiking trails.
Treasure Beach (formerly Trash Beach): Located on the island's windward side, this beach offers excellent beachcombing opportunities. Despite its former name, recent conservation efforts have transformed it into an appealing destination for those seeking solitude.
Hidden Coves: Our knowledge of Culebrita's coastline allows us to access smaller, unnamed beaches that provide complete privacy for those seeking the ultimate secluded experience.
Wildlife and Marine Life
Protected Ecosystem
As part of the Culebra National Wildlife Refuge, Culebrita hosts remarkable biodiversity within its small footprint. Environmental surveys have documented 97 plant species, 32 bird species, and various reptiles and mammals thriving in this protected environment.
Marine Wildlife Encounters
The waters surrounding Culebrita teem with life. Green sea turtles, listed as federally endangered, find sanctuary in the seagrass beds around Tortuga Beach. Southern stingrays glide through the shallows, while colorful reef fish populate the coral formations. Brown pelicans and white-cheeked pintails represent the threatened and endangered bird species that call the island home.
Responsible Wildlife Observation
Our tours emphasize ethical wildlife viewing practices. We maintain appropriate distances from nesting sites and feeding areas, ensure our presence doesn't disrupt natural behaviors, and educate guests about conservation efforts protecting these species.

Navigation and Seasonal Considerations
Optimal Conditions and Timing
Our decades of experience navigating to Culebrita have revealed specific patterns that dramatically affect the quality of your experience:
Seasonal Weather Patterns:
December-April: Generally calmer seas with excellent visibility, though occasional northern swells can affect the Natural Baths experience
May-July: Ideal conditions with minimal wind and exceptional water clarity
August-October: Warmest water temperatures with increased afternoon thunderstorm probability
November: Variable conditions requiring flexible scheduling
Daily Timing Strategies:
Morning Departures (7:30-8:30 AM): Calmest seas and optimal photography lighting
Midday Options: Maximum warmth for extended water activities
