Puerto Rico's Pristine Island Escapes. Explore 20 attractions across the island.
Vieques and Culebra are the antidote to overbuilt Caribbean tourism, and getting to them is half the adventure. The ferry from Ceiba takes about 30 minutes to Culebra and roughly an hour to Vieques, but schedules are famously unreliable - seasoned travelers book a morning Cape Air or Vieques Air Link puddle jumper from San Juan's Isla Grande airport instead.
On Vieques, the star attraction is Mosquito Bay, certified by Guinness as the brightest bioluminescent bay in the world. Book an electric-boat tour with Abe's Snorkeling & Bio Bay Tours or a kayak excursion with a licensed operator for a new-moon night, when the dinoflagellates glow most intensely - every paddle stroke ignites trails of blue-green light beneath the surface. During the day, rent a Jeep and head into the Vieques National Wildlife Refuge, which covers two-thirds of the island. The refuge roads are unpaved and sometimes brutal, but they lead to beaches that rival anything in the Caribbean. Playa La Chiva (Blue Beach) is a long crescent with calm, snorkel-friendly water and shaded picnic areas. Playa Caracas (Red Beach) has the best facilities and easiest access. For solitude, keep driving past the tank range to Playa La Plata or Playa Platita, where you may have the sand entirely to yourself.
In the refuge's western unit, Sun Bay is the only beach with a lifeguard and formal parking, and the adjacent Media Luna cove is ideal for small children with its shallow, protected water. On the cultural side, the hilltop Fortin Conde de Mirasol in Isabel Segunda is the last Spanish fort built in the Americas and now houses a small museum tracing the island's Taino, Spanish, and military history. The Esperanza waterfront malecon comes alive in the evening with open-air bars and the smell of mofongo drifting from restaurants.
Over on Culebra, Flamenco Beach is the headline act and deserves its reputation - a horseshoe bay with flour-white sand, clear turquoise water, and rusting military tanks on the beach that have become folk-art canvases. But do not stop at Flamenco. Rent a golf cart and drive to Zoni Beach on the island's east end for windswept beauty and sea turtle nesting habitat, or hire a water taxi from the town dock to Culebrita, an uninhabited islet with tide pools, nesting seabirds, and the ruins of a 19th-century lighthouse. The snorkeling off Tamarindo Beach is exceptional, with sea turtles regularly grazing in the seagrass beds just offshore.
The brightest bioluminescent bay in the world glows most spectacularly during the new moon phase. Electric boat and kayak tours depart from the Esperanza side of Vieques. Book with licensed operators like Abe's Snorkeling & Bio Bay Tours and avoid swimming in the bay, as sunscreen damages the dinoflagellates.
A Jeep or high-clearance SUV opens access to over a dozen beaches within the 18,000-acre refuge. Playa La Chiva (Blue Beach) has calm snorkeling water, Playa Caracas (Red Beach) is the most developed, and the remote eastern beaches like Playa La Plata offer true solitude. Gates close at sunset.
On Culebra's northwest coast, this rocky beach is less scenic for sunbathing but outstanding for snorkeling. Hawksbill and green sea turtles graze in the seagrass beds just 20 yards from shore. Bring your own gear - there are no rentals on site.
An uninhabited islet off Culebra's eastern tip, reachable by water taxi from the Dewey town dock. Hike to the ruins of the 1886 lighthouse for panoramic views, swim in natural tidal pools, and snorkel the reefs offshore. Bring water, food, and sun protection - there are no facilities.
Consistently ranked among the top beaches in the world, Flamenco is a wide horseshoe of white sand backed by low hills. The painted military tanks at the north end are a popular photo spot. Arrive early on weekends to claim shade under the few trees. Basic food vendors operate near the entrance.
Vieques has drift dives along its southern wall and wreck dives including a cargo barge at around 60 feet. Culebra's Luis Pena Channel Natural Reserve protects coral gardens teeming with parrotfish, barracuda, and nurse sharks. Culebra Divers and Blue Caribe Dive Center are the go-to shops.
Perched on a hill above Isabel Segunda in Vieques, this is the last Spanish fort constructed in the Americas. The small museum inside covers Taino artifacts, the island's sugar plantation era, and the US Navy's controversial decades of weapons testing. Admission is a few dollars.
Several operators offer rides through the countryside and along secluded beaches on the island's west end. Rides pass through former sugar cane fields where free-roaming Paso Fino horses graze, a legacy of the island's agricultural history.
