Description
Route to the historic Guaniquilla Train Tunnel, built in 1908 as part of Puerto Rico's coastal railway and used until around 1956, when rail service in Cabo Rojo came to an end. The tunnel is located off PR-307, km 5.0 interior, in the Guaniquilla sector, near the Punta Guaniquilla Nature Reserve on private property.
From the access point, the tunnel is reached in about three to four minutes on foot. The full route covers approximately 2.6 km through the dry coastal scrubland typical of southwestern Puerto Rico.
