Description from the publisher
Tunnel constructed in 1911 serving the sugar cane plantations of the area. The south portion of the tunnel connects Guajataca and Pastillo Beaches. The tunnel once served as pathway for the trainways that used to transport materials and produce from the sugar cane plantations. In 1953, the tunnel was last used and has since been prepared for travelers that wish to transport themselves to Puerto Rico's sugar cane era.
How to get there
Take road PR #2 towards Isabela. Follow the signs towards Guajataca Beach.
I try to visit this place very time I go to PR. There are couple of shops were you can get a good Pina Colada, and then walk through the tunnel and see the Ocean. This is not a good place for swimming, severe dangerous currents.
