What is the Guajataca Tunnel?

The Spanish started the Puerto Rico rail system in 1888.

They took almost 20 years to complete the route from San Juan to Ponce

When the American Troops arrived in Puerto Rico during the Spanish-American war in 1898, the railroad system consisted of 168 miles of tracks.

In 1902 The American Railroad Company (ARC) from New York acquired Puerto Rico’s railroad system. In that same year, passenger travel began to grow.

The ARC expanded the railroad to the west of San Juan. This included the towns of Arecibo and Aguadilla, and they wanted to link the railroad line through the towns of Quebradillas and Isabela.

Because of the area’s topography, they needed to build two tunnels and a bridge.

In 1904 the American Railroad Company dug a tunnel through the mountain that separated Guajataca’s Beach in Quebradillas and Pelicanos Beach in Isabela, completing the Guajataca Tunnel.

The tunnel was in service until 1957 when commercial travel ceased. Passenger traveling ceased in 1953.

Allow me to share with you the legend of the train wreck.

In November of 1910, on a trip from San Juan to Aguadilla, the train could not slow down sufficiently and derailed exiting the tunnel.

In this accident, 16 people died, and 50 were injured. People said that the tunnel was haunted and that you could hear the voices of the train wreck victims.

In 2000, the Puerto Rico Government declared Guajataca Tunnel a Historical Monument.


Where is it located?

You will find Guajataca Tunnel on Guajataca Beach, where the towns of Quebradillas and Isabela meet.

Guajataca Beach is great for lounging in the sun, but currents make it too dangerous to swim here.

There is plenty of free parking space, and you do not have to pay to enter the tunnel.

Another thing you can do is go to Tunel Negro or Black Tunnel.

In 1906, The American Railroad Company of Puerto Rico built another tunnel a couple of miles from Guajataca Tunnel.

The Black Tunnel is the longest of both tunnels and was joined by a steel viaduct 250 feet long at an elevation of 131 feet above the river level. 

You have to walk for half an hour up the Guajataca river to reach the Black Tunnel. Once you enter the tunnel, you will know why it is called Black Tunnel.
