Things to Do in La Parguera, Puerto Rico: cays by day, the glowing bay by night.
La Parguera is a waterfront village in Lajas, on Puerto Rico's southwest coast and the nearest bio bay to the west coast. The best things to do: a boat to the mangrove cays by day, sunset at Caracoles island, and the bioluminescent bay after dark. It is about an hour from Ponce, 1 to 1.5 hours from Rincón and about 2 to 2.5 hours from San Juan.
Where is La Parguera? The bio bay for Puerto Rico's west coast
La Parguera is a waterfront village in the town of Lajas, on the southwest corner of Puerto Rico. It is the nearest bio bay for visitors on the west coast: about 14 miles from Cabo Rojo, 21 from Mayagüez and 34 from Rincón. Its bioluminescent bay, locally called Bahía Fosforescente, lies inside La Parguera Nature Reserve.
The La Parguera Nature Reserve has been protected since 1979. It covers mangrove bays, salt marshes and many small islands, among them Mata la Gata and Cayo Caracoles, and coral reefs such as La Pared.
Best things to do in La Parguera
The best things to do in La Parguera follow the light: take a boat out to the mangrove cays by day, watch the sunset from Caracoles island, and see the bioluminescent bay glow after dark. Add a walk along the waterfront village and, if you have a full day, a stop in historic Ponce on the way.
See the bioluminescent bay after dark
The bay is the reason most visitors come. On our La Parguera sunset boat and bio bay tour, an 8-minute boat ride brings you to the lagoon, where a microscopic plankton, Pyrodinium bahamense, flashes blue-green as the water moves.
Watch the sunset at Caracoles island
Caracoles is a mangrove island about a 5-minute boat ride from the village, and the sunset stop on our tour, where kids get snacks and refreshments and adults get rum drinks and beer, while you relax on the boat as the sun goes down.
Take a boat to the mangrove cays
The village is ringed by cays rather than beaches. Some of the most visited are Cayo Enrique, Mata la Gata and Cayo Caracoles, and you reach them by renting a small boat or with a local tour provider, as Discover Puerto Rico notes.
Spot Isla Magueyes from the water
Isla Magueyes sits just offshore, with marine science buildings on its western end and a colony of iguanas across the island. It is kept mostly for research and the iguanas, so enjoy it from the boat.
Walk the waterfront village
Homes and docks line the water's edge, with boats tied up beside them. It is a relaxed place to wander before your evening on the water.
See the cays from the hill above the village
The hills behind the village look out over the marina and the scattered mangrove cays, the best way to see how many small islands surround the bay.
Drive the Lajas Alien Route
Lajas has a playful claim to fame: the Puerto Rico Alien Route, which passes a landing strip a local resident built to welcome visitors from outer space, according to Wikipedia, citing CBS News.
Add Ponce for a day of history
Ponce is about an hour east. Its main square, Plaza Las Delicias, holds the Lions Fountain, the cathedral and the red-and-black Parque de Bombas. Our $199 tour option includes a stop at Ponce's historic town square.
La Parguera at night: sunset at Caracoles and the glowing bay
At night, La Parguera's highlight is its bioluminescent bay, where a microscopic plankton lights up when the water moves. The classic evening starts with sunset at Caracoles island, a 5-minute boat ride from the village, then a short ride to the lagoon after dark. On our tour that second ride takes 8 minutes.
When is the La Parguera bio bay at its best?
The La Parguera bio bay is at its best on a dark night, when no bright moon washes out the glow. Our tour runs on select nights each month, a few nights after the full moon, when the moon rises late and the evening sky is darker. The moon calendar marks every tour night.
