San Cristobal Canyon is the only volcanic rift in Puerto Rico
and is approximately 650 feet down to the bottom. The temperature
at the top is considerably cooler than down in the canyon. The
canyon is about 9 kilometers long. There are two rivers running
through it and several waterfalls. It isn't easy to see. There
is no built 'Tourist' access road, it is just there. It is located
about half way between Barranquitas and Aibonito. Lovely and cool
at the top, it is much warmer at the bottom.
is off #725 on the south side and also around the north side there
are several access and one along the western side.
La Piedra Restaurant sometimes sponsors hikes into it and Felix,
a guide, often takes people on a Saturday. It is not an easy climb
into the canyon and back out again, but it is relatively easy
to just gaze into it. For the more adventurous and in shape it's
a great days exploration.
