EL YUNQUE NATIONAL FOREST
with a private Certified Interpretive Tour Guide
Many people say that there are no
animals in the Forest because they
don´t see as many animals during
daylight as they expect.  It will depend
where, when, and how to look at
Nature.  When you join a night hike you
have a better opportunity to experience
the awakening of the Forest´s night
creatures with all nocturnal orchestral
sounds in crescendo.

Although more sounds can be heard
on the upper level, at this moment, the
night hikes are offered on the lower
part of the Forest for two main
reasons:  safety and sustainable
practices.

Safety.  Only those with reservations are
admitted to El Portal Visitors Center during the
night by the Security Staff.  Parking and restroom
are available for our clients.  In addition, we use
an easy trail that allows us as many stops as
necessary during our hikes.

Sustainable practices.  Our main goal during
the night hikes is to find the coquí, walking stick,
the Puerto Rican Screech Owl and Puerto Rican
Boa.  The nocturnal fauna of El Portal Trail
includes lizards, tarantulas, geckos, scorpions,
moths, grasshoppers, and other species.  

A trail that normally takes 15 - 20 minutes, during
the night is covered in not less than 1-1/2 hour.  
It i offer for individuals, extended families, and
groups on a private basis.  In this way, we make
sure that the trail is not used every night.
