pleasant places to enjoy a picnic lunch. Free Admission, open 8 a.

half day's tour.
Rio Camuy Caves
Some say that you take only one sightseeing trip, it should be to Rio
Camuy Cave Park. This incredible 268-acre park is the site of the
great subterranean caverns carved out by the Camuy River over
one million years ago. The impeccably maintained trails gently
descend 200 feet through a fern filled ravine to the yawning,
cathedral-like caverns. The caves are home to a unique species of
fish that is totally blind. To visit this pristine site is to be transported to
another, hidden world. Rio Camuy Cave Park is the third-largest
cave system in the world. Sixteen entrances have been found and
11 kilometers (7 miles) of passages explored so far. One special
attraction is the Cuerva Clara, which measures 695 feet (210m) in
length. The park is equipped with picnic areas, walking trails, food
facilities, and exhibition hall and a souvenir shop, making it the
perfect place to spend a day. Reservations are essential, as this
place is understandably popular. Open Wednesdays through
Sundays and all holidays, 8:00 a.m. to 4:00 p.m. For information call:
(787) 898-3100 or (787) 763-0568. There are only two other places in
the world where you will find a cave system as massive or dramatic
as the Río Camuy Cave Park – and neither of them has a tropical
underground river thundering through it!

Arecibo Observatory
The Arecibo Observatory is home to one of the world's most powerful
radar-radio telescopes, and the largest single-unit radio telescope
in the world. It is powerful enough to receive signals transmitted by
a comparable telescope located 1,000 light-years away. Those
who see the Arecibo radio telescope for the first time are astounded
by the enormousness of the reflecting surface, or radio mirror. The
huge "dish" is 1000 feet in diameter, 167 feet deep, and covers an
area of about twenty acres. The surface is made of almost 40,000
perforated aluminum panels, each measuring about 3 feet by 6
feet, supported by a network of steel cables strung across the
underlying karst sinkhole. The antenna can be moved in any
direction, making it possible to track a celestial object in different
regions of the sky. The observatory was developed by the National
Astronomy and Ionosphere Center and it is operated by Cornell
University under a cooperative agreement with the National
Science Foundation. The facility is open to the public Wednesday-
Friday, noon-4 p.m., Saturday and Sunday 9 a.m.-4 p.m. For
information call: (787) 878-2612. In the northwest mountains of the
island, nestled among the karst-country hills, is the Arecibo
Ionospheric Observatory, or Radio Telescope, the largest of its kind
and one of the most important research facilities on the face of the
earth.
