We did this tour while on a Royal Caribbean
cruise. This was the BEST excursion I have
ever done. Glad you are up and running again!

If you are short of time or you are
not part of a larger group, this
could be your best option to see El
Yunque when the crowds are gone
!

The trail at El Portal is a short loop
trail of 0.3 miles within the land of
an old coffee plantation, Hacienda
La Catalina. This are is an excellent
example of  Secondary Forest.

We will walk in the dark in search
of critters and the glow-in-the-dark
cocubá as our Ancestors did.
Depending on the season, you will
see endemic species coexsiting
with other (coffee, breadfruit,
plantain, and papaya trees) . Our
target species are newborn coquis,
glow-in-the-dark mushrooms,
lizards, critters, and the cocubá.

Mucarito), please click

Derek England  recommends AdvenTours Puerto Rico.

Hilda is amazing!!! She was able to accommodate a tour for my family of 12 people at the last minute. She
arranged a guide and transportation. My whole family agreed that the night time walk through the El Yunque rain
forest was the highlight of our trip. We loved seeing the frogs, lightning bugs, snails and hearing the laughing owl.
This was a fantastic trip. I highly recommend it to anyone.

In Search of the Cocubá
In search of glow-in-the-dark cocubá
* Night hikes at El Yunque National Forest since 2001 *
.
.
.



Explore the trails of El Yunque and you will have the  unique
experience of seeing
glow in the dark bacteria, insects,
microorganisms, and mushrooms in their natural environment.

Our target species are newborn coquis, glow-in-the-dark
mushrooms, lizards, critters, and the cocubá
.
We need at least three or four
consecutive days of rain to be able to
find
glow in the dark mushrooms.
Depending on selected hike and the elevation of the trail, we will be going
through different habitats.  As soon as night arrives, the musicians of the
nocturnal orchestra of the Forest will start playing and the singers will
greet you with with their songs.  But wait, were these the first and only
sounds the europeans heard when they arrived in Borikén?

Listen careful to the rythm of the maracas, ocarinas, and mayohuacan.

Join Richard, our Master Guide

Imagine yourself growing over 1,400´ above
sea level,
with exposed buttress roots
helping you to stabilize on unstable soils
near river banks and steep cliff edges?
The shallowness of the soil makes you
the dominant species at this height  of the
Forest.   But you are not alone, other trees,
plants, and shrubs have adapted, including
your two friends: the old trees with red
crooked bark and those tall tress
with a strong distinctive fragrance.

We will be looking at everything:  from small
flowerless bryophytes, elegant giant tree ferns,
diminute newborn coquis, glow-in-the-dark
mushrooms, bats, owls, and any other critter.

Where we go?  Palma de Sierra, Moun
