Puerto Rico
Vieques
Mosquito Bay, often called the brightest bioluminescent bay in the world, plus beaches kept wild by six decades as a Navy range.
Vieques is a quiet, hilly island off Puerto Rico's east coast, reached by ferry or small plane. For six decades the US Navy held most of it, and when the Navy left in 2003 that land became a wildlife refuge, which is why so many of its beaches are still empty and undeveloped. Its icon is Mosquito Bay, a mangrove lagoon that glows blue-green at night with bioluminescent plankton. Wild horses wander the roads between the two small towns, Isabel Segunda on the north coast and Esperanza on the south.

When to avoid Vieques
No month is graded one to avoid, but July-November is hotter and wetter, and the Atlantic hurricane season peaks around August-October, when a storm can stop ferries and flights. The bay glows all year; plan bay tours around the new moon, as bright moonlight drowns out the glow. Ferries fill up on holiday weekends.
Top things to do in Vieques
-
Mosquito Bay - kayak the bioluminescent bay
nature wildlife adventure ⭐ Highly recommendedPuerto Mosquito, a mangrove-ringed lagoon on the south coast, holds dense blooms of dinoflagellates that flash blue-green whenever the water is disturbed. Guided kayak and electric-boat tours leave from the Esperanza side after dark; swimming is no longer allowed, to protect the bay. Go near the new moon, when the glow is strongest.
-
Vieques National Wildlife Refuge - the east-end beaches
nature wildlife scenic ⭐ Highly recommendedThrough the refuge gate on the east side, dirt roads lead to a string of beaches on former Navy land: Caracas, also called Red Beach, Pata Prieta, also called Secret Beach, and La Chiva, also called Blue Beach. Calm, clear water, sea grape shade and very few people. The refuge is open by day only, and there are few facilities, so bring water and food.
-
Sun Bay - the island's public beach
scenic 👍 PopularBalneario Sun Bay, just east of Esperanza, is a long, palm-backed crescent of pale sand with lifeguards, facilities and a campground, and horses often grazing under the trees. Smaller Media Luna, a little further along, has shallow, calm water good for children, and Navio beyond it gets more waves.
-
Fortin Conde de Mirasol - the last Spanish fort
historyOn the hill above Isabel Segunda, this small fort begun in the 1840s is usually described as the last fort Spain built in the Americas. Restored as a museum, it covers the island's Taino past, the sugar era and the Navy years, and looks down over the town and harbour.
-
Punta Mulas Lighthouse - the harbour light at Isabel Segunda
history scenicA small 19th-century Spanish lighthouse on the point beside the ferry harbour at Isabel Segunda. Walk out for the view across the sound towards the main island, and combine it with the fort on the same morning.
-
Playa Negra - the black sand beach
scenic nature wildlifeWest of Esperanza, a short walk down a dry creek bed brings you out on a small beach streaked with dark volcanic sand, framed by low cliffs. It is not for swimming when the sea is up, but it is one of the island's oddest and most photographed corners.
-
Mosquito Pier - snorkel the old Navy pier
nature wildlifeOn the north-west coast, a long pier built by the Navy reaches out into the sound. The pilings and rubble along it attract turtles, rays and reef fish, making it the island's best-known shore snorkel when the water is calm.
-
Esperanza malecon - seafront eating and sunsets
food 👍 PopularThe short seafront strip in Esperanza is the island's social centre, lined with open-air bars and casual restaurants looking across to tiny Cayo Afuera. Come at sunset for fresh fish, mofongo, empanadillas and a cold drink, with the odd horse passing by.

Getting to & around Vieques
Getting there
Fly into San Juan (SJU), then take a short small-plane hop to Vieques or drive to Ceiba for the ferry to Isabel Segunda
Flight
Antonio Rivera Rodriguez Airport (VQS)
Small planes fly in from San Juan's main airport, Isla Grande and Ceiba, landing on the north coast a short drive west of Isabel Segunda. Publicos and taxis meet flights, though most visitors pick up a rental jeep here.
Ferry
Isabel Segunda
Passenger and cargo ferries cross from Ceiba on Puerto Rico's east coast, about an hour by car from San Juan; sailings can sell out and run late, so book ahead and leave slack
Getting around
Rental jeep
The way most visitors get around, and the only practical one for the refuge beaches; the island's small fleet sells out, so book well ahead
TBC
Publico
Shared vans and taxis meet the ferry and planes and run between Isabel Segunda and Esperanza; scarcer after dark
TBC
Bicycle
Rentable in town and fine for Esperanza and Sun Bay; the hills and heat make longer rides hard work
TBC
Walking
Esperanza is walkable end to end, as is the centre of Isabel Segunda; everything else needs wheels

Vieques's smaller, even quieter neighbour to the north is home to Flamenco Beach, regularly ranked among the best in the Caribbean, and reef snorkelling at Tamarindo and Carlos Rosario. Boat trips usually combine beaches with a snorkel stop.
Getting there
tour | flight
By boat charter across the sound or a short small-plane hop
The west end
Half dayBeaches and Navy relics
Drive out through the former Navy depot, past rows of grassed-over ammunition bunkers and the island's giant old ceiba tree, to Green Beach at Punta Arenas, with calm water, snorkelling and views across the sound to El Yunque. Stop at Mosquito Pier on the way.
Getting there

About 20-30 minutes by car from either town
El Yunque
Full dayRainforest national forest
The only tropical rainforest in the US national forest system rises on the mountains you can see from Vieques's west end, with waterfalls, viewing towers and short trails. A long day that only works if your crossings run to time; easier on the way home.

Ferry or flight to Ceiba, then about 30-45 minutes by car
A little history of Vieques
Taino people lived on Vieques long before Europeans arrived, and for centuries afterwards the island was a contested backwater, claimed by Spain and raided or briefly settled by rivals. Spain only took firm control in the 19th century, founding Isabel Segunda in 1843 and building the fort above it, and sugar plantations worked by enslaved and later contract labour spread across the lowlands. The island passed to the United States with the rest of Puerto Rico in 1898.
From 1941 the US Navy acquired around two-thirds of the island, using the west end as an ammunition depot and the east end for training and live-fire exercises, while the islanders lived in the strip between. Military use ended in 2003, and the former Navy lands became the Vieques National Wildlife Refuge, which is why so much of the coast is still undeveloped. Parts of the old range remain closed while unexploded ordnance is cleared.

FAQs about Vieques
▸ When is the best time to visit Vieques?
December-June is the most comfortable stretch, drier and a little less hot. July-November is hotter and wetter, and the hurricane season peaks around August-October, when storms can disrupt ferries and flights. The bioluminescent bay glows year-round, so time a visit around the new moon rather than the season.
▸ Can you swim in the bioluminescent bay?
No. Swimming in Mosquito Bay was stopped to protect the organisms that make it glow, and tours now go out by kayak or electric boat with a guide. You can still trail your hand in the water and watch it light up. Skip insect repellent and sunscreen before a tour, as they harm the bay.
▸ Do you need a car on Vieques?
Practically, yes, if you want the refuge beaches, which are reached on rough roads with no public transport. Rental jeeps on the island are limited and sell out in busy periods, so book when you book your room. Mainland rental cars are generally not allowed on the ferry.
▸ Is it safe to explore the old Navy lands?
The open parts of the wildlife refuge are safe to visit, but parts of the former bombing range are still closed while unexploded ordnance is cleared. Stick to signed roads and beaches, never go past closed gates or fences, and do not pick up metal objects on the shore or in the water.
▸ Vieques or Culebra?
Vieques is bigger, with two towns, more places to eat and stay, the bioluminescent bay and many beaches to spread out across. Culebra is smaller and sleepier, with Flamenco Beach and the better reef snorkelling. Both need the same ferry or flight from the east coast, and many people visit one from the other.
