Cabo Rojo - The phosphorescent bay off of the coast of La Parguera, a small fishing village on the Southwest corner of Puerto Rico offers a luminescent effect in the bay as the result of a permanent population of tiny micro-organisms called Dinoflagellates. These animals produce a chemical spark of light when disturbed in the water. They can produce striking effects of green and white sparkles that can only be seen at night....and no, don't worry - it's not radioactive! 

There is also the Cabo Rojo lighthouse and Playa Sucio - despite its name, one of the most beautiful beaches on the West Coast.  Stop in Boqueron for local oysters or clams.

Camuy River Cave Park 

There are only two other places in the world where you will find a cave system as massive or dramatic as the Río Camuy Cave Park - and neither of them has a tropical underground river thundering through it! Visitors ride a trolley that descends into a sinkhole lined with dense tropical vegetation while a guide describes the sights. After a walk across ramps and bridges and through the dramatically illuminated, 170-foot high Cueva Clara, another tram shuttles you to a platform overlooking the 400 foot deep Tres Pueblos Sinkhole.

Another attraction is the Spiral Sinkhole and Cave. You can walk the 205 steps down into the sinkhole, but the cave itself is off limits to all but experienced spelunkers. The sinkhole is believed to have once been an enormous cavern, and is indeed an impressive sight. Cathedral cave is home to an enigmatic collection of petroglyphs etched into the walls by the ancient Taínos (native Indians).

The park is normally open Wednesday through Sunday from 8:30 a.m. to 4:00 p.m. The last tour departs at 3:30 p.m., or when the park reaches its daily capacity.

The Guánica Dry Forest Reserve: 10,000 acres of dry land inhabited by over 600 uncommon types of plants and animals, including 48 endangered species and 16 that are unique to Puerto Rico! A surprisingly captivating terrain, splashed with pastel colors and bursting with wildlife, Guánica's Dry Forest is the perfect counterpoint to the verdant El Yunque Rainforest.
Nature's creative touch is just as enthralling in Guánica. This United Nations Biosphere Reserve is especially alluring to hikers and cyclists, as they forage far into the Dry Forest through twelve trails of varying difficulty. You can also enjoy the uncommon scenery by car on the narrow road that hugs the border of this strikingly scenic, desert-like expanse.
Puerto Rico is so ecologically diverse within such a small stretch of land that a visit to Guánica's Dry Forest Reserve may well require bringing along both a bathing suit and good pair of walking shoes. One of the most beautiful beaches on the island is located right next to the Dry Forest, and nearby you will also find the attractive Copamarina Beach Resort. Go on a day-long tour, or stay a few more days in order to get the full flavor of Porta del Sol, the southwestern region.
