Bosque de Guajataca

Guajataca protects a stretch of the northern karst where the limestone has been eaten into sinkholes, ridges and caves, and around forty kilometres of trails run through it, the best known ending at Cueva del Viento, a chamber with a chimney of light where the trail passes right through the rock. The forest is dense and the mogote hills make the walking steeper than the map suggests. Below, the Guajataca reservoir sits in a drowned valley. On the coast a few minutes away, the Tunel de Guajataca is a short railway tunnel from the early twentieth century cut through the headland, now a walk from a small beach with a view along the cliffs.

What you actually see

• Cueva del Viento - a cave chamber the trail passes through.
• The karst trails - around forty kilometres through sinkholes and ridges.
• Guajataca reservoir - the drowned valley below the forest.
• The old railway tunnel - cut through the coastal headland nearby.

When to go

December to April is drier and the trails less slippery; limestone here is treacherous when wet. Take a torch for the cave. The forest office keeps limited hours and trail markings have deteriorated, so download a map before going.

Honest expectations

Trail signage is poor and several routes are overgrown or unmaintained since the hurricanes, so it is easy to get turned around; go with a map and tell someone your plan. The cave needs a torch and has an awkward scramble. There is no water or facility once you leave the entrance.
