  • This guided tour will explore the Río Camuy Cave Park, located in Puerto Rico's northwestern region. The caverns are part of an extensive network of natural limestone caves and underground waterways carved out by the Río Camuy which is the third largest underground river in the world. While the cave system was officially discovered in 1958 archeological evidence shows that the caves were explored hundreds of years ago by the Island's indigenous inhabitants. Over 10 miles of caverns, 220 caves, and 17 entrances to the Camuy cave system have been mapped. However, this is only a fraction of the entire system, which many experts believe still holds another 800 caves. Only a small part of the complex is open to the public.

    *The caves are large (size of a dome resembles a sports arena), well lit, and the paths are paved and include staircases with railings.  Nevertheless, the stone surface is usually wet due to high humidity and very slippery. The caves serve as a home for multiple bat colonies.

  • Inaugurated in 1899, these historic waterworks were at the time the most advanced water purification facility in Puerto Rico. They were planned and built prior to the Spanish-American War of 1898 and constitute the only Spanish-period aqueduct on US territory that still retains most of its integrity. This historic site is beside the grounds of the Río Piedras Experimental Station and the University of Puerto Rico Botanical Garden, which are places of lush vegetation and a rich diversity of bird species. Snacks and water will be provided.
  • Date: Monday, 20 June
  • Time: 1:00 PM – 3:30 PM
  • Cost: $70
  • Pack the following:
    • Fresh and comfortable clothing that protects you from the sun
    • Hat or cap
    • Comfortable closed shoes. No sandals or flip flops.
    • Use mosquito repellant and sunscreen.
    • Bring your reusable bottle for water or liquids that you are going to consume.

  • During this guided tour, you will visit the remains of one of the most important sugarcane haciendas of the 19th century. Its historic site includes a sugar mill steam engine that is the only one of its kind still in existence. Among the green landscape of this alluvial plain you’ll also find the rehabilitated structure of Marqués de La Esperanza’s former residence, which today accommodates an important machete collection from the period and other facilities. At Hacienda La Esperanza, nature and history coexist thanks to the Río Grande de Manatí, one of the most important rivers in Puerto Rico. To this very day, its waters are intimately linked to all things living in this nature reserve.

  • Join a resident expert on the Old San Juan for a 3-hour walk through the cobblestone streets of the colonial city. The stroll includes historical sites, favorite places of the sanjuaneros (bohemian local residents), and an opportunity to visit unique architectural spaces away from the beaten path.

    During the tour, you will explore the colonial quarters of San Juan, the capital of Puerto Rico, founded by the Spanish conquistadors in 1521. This is not only the oldest city in the United States, but one of the two oldest European cities in Latin America. In contrast with the capitals of the neighboring islands, Old San Juan has preserved its historical identity and architectural integrity thanks to the activism of the local cultural luminaries who managed to have new construction banned and ensured that any restoration works, including those in private houses, could be done only with the permission of the Institute of Culture. Today’s urban legends, modern folklore, and a lively discussion of Puerto Rico’s ambiguous political status will help you connect past with present and emerge from the tour with a new understanding of this unique Caribbean island and its people.

  • ENLACE is a public corporation set up by the government of Puerto Rico to provide the local residents and organizations a means of collaborating on improving the Caño Martin Peña communities and the canal itself. A crucial part of ENLACE is the establishment of a community land trust, to inoculate against gentrification through collective ownership of land.

    This organization attends the needs of the community of Caño Martín Peña, a disadvantaged community within 10 minutes from Puerto Rico Convention Center, with a number of infrastructure challenges. They also have an adult literacy program. This activity will include a combined (bus/walk) tour of the community and the areas neighboring Fideicomiso de la Tierra (the land trust) together with the trust representative, followed by a volunteer activity to help the Trust fulfill its mission. Volunteers usually perform tasks such as restoration, cleaning, and painting of community areas (schools, green areas, etc.).

  • The Bioluminescent Bay Kayak Tour is an unforgettable experience offered by only five bays in the world, three of them located in Puerto Rico. The bioluminescent bay, surrounded by the mangrove trees, contains a special species of zooplankton, which emits light when activated by contact with moving objects. As if by the will of an invisible wizard, your hand suddenly shines with glistening lights as you move your fingers through the water, and on the moonless nights you may be able to see the sparkling contours of fish swimming by your kayak Intensity may vary depending on the tide and the phase of the moon.

Bioluminescent Bay Tour in Puerto Rico

  • The Conservation Trust of Puerto Rico originally acquired most of the lands that make up Las Cabezas de San Juan Nature Reserve in 1975. Located on the northeastern tip of Puerto Rico, the site’s name—Las Cabezas de San Juan— refers to the three head-like promontories that extend into the Atlantic Ocean. The Historic Fajardo Lighthouse sits on top of one of these vantage points, enjoying an incomparable view that extends to much of the surrounding islands and cays, including Vieques and Culebra. The Trust saved this area of invaluable ecological importance from being developed into a touristic project complete with a marina. Officially designated a nature reserve in 1986 by the Department of Natural and Environmental Resources and the Puerto Rico Planning Board, this area is well known for its Laguna Grande— one of three water bodies with year-round bioluminescence known in Puerto Rico. Only steps away from many hotels and tourist destinations, the reserve and its lighthouse have also become one of the area’s most popular attractions.

  • The Hacienda Buena Vista Natural Protected Area is located in a mountainous sector between Adjuntas and Ponce, where the Canas River flows south towards the Caribbean. The river was essential for the hacienda, as an intricate system of waterworks was built to draw water from it and to power several hydraulic machines that have been carefully restored to working conditions. A sub-tropical humid forest rich in plant and animal life characterizes nature in the area. Small plots of coffee, cacao and fruit trees still grow here under the shade of wood-producing trees. In September 1987, Hacienda Buena Vista became the first Para la Naturaleza site to open a visitor center and has since become one of the region’s main tourist attractions.
