he island of Guam was once considered by locals to be one of the
world's best kept diving secrets. But
more and more people are now discovering the incredible variety found in
this undersea paradise.
As a U.S. Territory, Guam has long
been a popular destination for Asian
T
superb support system of dive shops
and guest facilities puts Guam at the
top of the list for scuba buffs.
Most tourist divers to Guam will want
to visit the World War Il shipwrecks,
historie sunken remnants now festooned in coral and inhabited by
shoals of fishes. The unique Guam
novelty dives like the undersea cave
Blue Hole or the fan-covered chasm
The Crevice are known for their water
clarity.
Boat diving is probably the easiest
way to approach the reefs and there is
a higher likelihood of seeing unique
fish and sea creatures at the outer
reef sites. At a few sites fish feeding
hasbecome a practice and swarms of
tiny tropicals greet the divers. On
Guam's deep reefs, look for the wilder
side with sea turtles, dogtooth tuna
and eagle rays commonly seen.
The Apra Harbor is usually well-protected from weather elements, so
tourists. A plethora of hotel, restaurant
and entertainment venues, combined
with numerous frequent flights in and
out, now makes Guam the most
diverse and convenient Pacifie Island
in the Micronesian region.
Just as the sunny Caribbean draws
people from the U.S., Guam's proximity and sandy beaches create a magnet for Asian divers. The consistently
warm and clear waters, great varieties
of fish and other marine life and a
4
hose used to organized diving will feel at home on the
Guam tourist boats as divemasters are present and
groups are usually kept to 4 to
6 per divemaster. Guam diving
can easily become a cross-cultural experience as divers from
many countries come aboard
to see the reefs.
There are a number of divemasters and instructors who
work with the local shops to
provide service on a one-toone basis. Instruction at ail levels from SNUBA and introductory
dives through master scuba instructor
can be found
here, with many
useful specialties
easily obtained
during your visit.
If you have
specifie sites in
mind or want to
T
even if the outer reefs can't be
reached, many harbor dives are available. The harbor dives are ail on hard
coral reefs or shipwrecks and offer
vast marine variety. Invertebrate life is
especially diverse in the harbor.
The outer reefs have great range
from deep dropoffs to coral heads and
sandy flats of garden eels. They are
homes to a wide variety of fish, sea
anemones and hard and soft corals.
Technical Diving Makes a Splash
echnica' diving has brought new innovations to
the diving world, allowing divers to explore
deeper, stay down longer and use special diving
techniques. Guam is one of the finest sites in the
Pacifie for technical divers to hone their skills. The
ciear waters, deep dropoffs, numerous shipwrecks
and availability of gases makes it the perfect venue
for new tekkies and those learning the advanced
techniques of deep water exploration.
Technical diving for the basic scuba enthusiast
us.ually entails the use of Nitrox, which is a higher mix of oxygen in the scuba tank.
Normally, only air is used in diving, but Nitrox allows divers to extend botlom time. It also
helps disperse accûmulated nitrogen from the blood, allowing divers to feel fresher at
the end of a day's diving. Other levels of tech diving extend from there to include the use
of rebreathers and TriMix gases.
Many types of training can be found on Guam to get the diver into this new realm.
Tech equipment is readily available at Guam's best equipped dive shops.

keep your group
small , ask the
local shops about
a private charter.
The larger charter boats also
offer early morning single tank
dives and afternoon/evening dives that include on
deck bar-b-ques and a night dive. Night
diving on Guarn is very good as a lot of
unusual invertebrates hide in the hard
corals du ring the day and come out
at night.
Guam's well-stocked dive shops offer
top name brands at very competitive
priees. Equipment repair is available for
most brands of dive equipment. For
those traveling light, rentai gear is also
easily obtained.
For photographers, Guam has a professional camera store carrying the latest equipment and many fine processing outlets including E-6 processing and
mounting.
Many shops can arrange packages
that include hotels, transfers and diving.

he southern
part of
Guam remains
largely rural and
undeveloped,
with tiny coastal
villages and
uninhabited
bays. Cocos
Island sits at the
far end of Guam and provides the
island with a southern barrier reef and
broad bay.
For divers, Cocos Wall is a sheer
drop with crimson sea whips and the
chance to see some big pelagies. Up
the coast, Toguan Bay is popular for
its swim-throughs and easy entry.
Spinner dolphins stay in this area and
can be se en frolicking in the mornings
and heading out to sea at night to hunt
for prey.
The Agat Bay area is full of sites for
divers. Agat Beach was a landing area
for the WWII U.S. invasion of Guam
and war
remnants
like a
sun ken
Amtrac can be
found along this
coast.
Hap's Reet is
a great place to
watch fish and
look at the huge
coral formations
in the bay.
Those who
like coral and
fishes will also
go for the Coral
Gardens located near the
Agat Marina.
The Shark Pit
is a favorite of junk divers. This old
military dump site has everything from
mess hall utensils to old war tanks and
trucks dumped long ago along a sheer
pinnacle. Swarms of pyramid butterflyfish now live at this site.
Because the bay fronts the open
sea, deep dropoffs provide the chance
to see some pelagie creatures including sharks, pilot whales and sailfish.
Rays such as mantas and eagles are
also found. Night dives here are colorfui and full of surprises.

he Blue !:Iole is one of the island's
finest novelty dives. Located toward
the tip of the Orote Peninsula on the
southern coast, the hole can usually be
seen 60 feet down from the surface as
the water is normally quite clear. It is a
popular spot, usually visited daily, and
has been the site of everything from
weddings and military re-enlistments.
It is basically a long, perpendicular
shaft that starts at the top of a sloping
reef fiat in about 60 feet of water. The
shaft itself extends down to about 300
feet, but at 130 feet a large window
opens tnthe outer wall, allowing the
diver to exit and ascend after a free fall
through the shaft.
As the Blue
Hole faces the
open ocean, it is
not unusual to
see large fish
here like barracuda and dogtooth tuna. Eagle rays
and a whale shark have been seen
gliding along the reef top and, on occasion, dolphins and pilot whales join
boats traveling to the hole.
This, and the nearby Crevice, are
sites most visiting divers like to have as
a log entry. When the current is right, a
drift dive between the two sites can
easily be made.
A popular site for fishwatchers is
Barracuda Rock, located
between the hole and
crevice. A small cave, swimthrough and large boulders
are found here.

uam's coastal waters are the
home of pods of dolphins called
spinners who use the island's shallow
bays for a number of reasons. Lucky
locals have even established a rapport
with the animais and have had regular
snorkeling sessions with them in the
southern end of the island.
The spinner dolphins cruise at
speeds between 5 to 7 miles an hour,
with a maximum speed of up to 22
mph. So, if the dolphins slow down
long enough to play with you, it is
because they want to.
It is this fact, among others, that
make a dolphin encounter on Guam a
special experience.
Unlike some Caribbean destinations,
there are no trained dolphins on Guam
to swim with . Ali dolphin encounters
are inthe-wild
happenings.
ln the
winter,
and
spring
months, Pacifie spinner dolphins
(stinella longirostris) come in to Guam's
calm bays.
They are easily identified as they
have slender bodies
and a long
thin snout
or beak.

By far the best known site is Guam's
popular tourist area, Tumon Bay, with
broad, sandy beaches and lots to do.
Tumon Bay is the ideal place for the
fishwatcher to ply his or her trade as it is
an outdoor aquarium with a nice variety of
undersea attractions.
Within these azure waters includes shallow reef flats, patch coral; coral thickets
and bright, white sand flats. Probably the
most popular SNUBA or snorkeling site is
at the bay's southern end at Ypao Beach.

pra Harbor is one of the main

areas on the island,
with diving playing a heavy role in these
activities. The harbor is blessed with
numerous and diverse coral reefs. Add
to that the fact that there are many
WWII remnants found in these waters,
and the numbers
of sites to see
become almost
endless.
One popular
site is Western
Shoals. It provides divers with
the opportunity to
experience
Guam's coral world in an environ ment
accessible to divers most of the year.
This reef is a honeycombed combination of branching and plating corals, a
variety of sponges, and provides shelter for Pacifie reef fish common to
Guam.
What is different about Western
Shoals is the fact that many of the
sponges are quite large in comparison
to those found on the outer reefs. An
I~
occasional sea turtle has been seen
streaking a diver here.
GabGab Reet is accessible by water
and by the Navy beaches. l1's deep
coral si opes and shelves house lots of
different invertebrates. Farther west,
Fingers Reet is a popular fish feeding
site. This offers scuba buffs a chance to
get closer to the reef's in habitants and
gives underwater photographers subjects that aren't timid.
Staghorn coral covers many areas of
the reeftop around Dry Dock Reet and
the DogLeg Reet to the north. Look for
healthy coral and even an occasional
hammerhead shark at the harbor mouth
at Hidden Reet.
There are many more patch reefs
with giant sponges and schooling
fusiliers and other attractions ail around
the harbor.

uam has a number of diveable
shipwrecks and airplanes that
were sunk during the battles of World
War II. Guam was a major invasion site
for American forces retaking the island.
On December 10,1941 , Guam surrendered to the Japanese South Seas
detachment forces after a valiant defensive struggle by the island's Insular
Force Guard. For 31 difficult months,
the people of Guam were subjects of
Japan. Guam was renamed 'Omiya
Jima' or Great Shrine Island.
Control of the island was eventually
transferred to the Japanese Navy in
1942. On July 21,
1944, known locally
as Liberation Day,
American forces
landed on Guam;
three weeks of bitter
warfare claimed thousands of Chamorro,
American, and
Japanese lives before the island was
declared safe and once again under
American rule. The island's strategic
position was quickly recognized by the
American military and was used as a
cammand post for U.S. Western Pacific
operations until the conclusion of the
war on September 2, 1945.

The island was shelled heavily for
weeks during the retaking . Air battles
grounded Japanese planes and then
invasion troops stormed much of the
southern and central western coasts.

And on a non-diving day, these remnants also exist in some places in the
hills and jungles. The bombs are at
times found during construction projects and by unsuspecting, and often
alarmed, bulldozer operators.
Just east of the green marker buoy
nearest the old seaplane ramp on the
Breakwater side of the harbor sits the
Tokai Maru. It is a Japanese freighter
sunk by a submarine torpedo attack
during World War II. Oddly enough, it
rests on another ship, the Cormoran,
which was scuttled during World War 1.
Thus, two victims of two different world
wars rest touching in the harbor.
The Tokai is by far the more popular
of the two as it is shallow enough to
overswim in one dive. This ship sits at a
list. The bridge area is quite open.
Inside there's the old wash area with a
tiled floor and sink. The shafts of light
coming through the doorways and
beams make a nice scene. The bow
area has black and orange rope

Ocean Spawns
Everything from coral to sea cucumbers
can be observed spawning on Guam .
The coral spawn may be the most spectacular, normally taking place after the

If the se as are calm, the corals are
more conducive mass spawns.
Researchers watch this annually to
study fertilization mechanisms and barriers, hybridization
and speciation events, recruitment of corals, and the effects
of water quality on reproductive and recruitment success.
Work with sea cucumbers is more applied, with the goal
being production of commercially valuable species to support an appropriate fishery for the Pacifie Islands.

ABOUTGUAM
uam is the southernmost island in
G
the Mariana chain, 30 miles long
and nine miles at its widest. Still, it is
the largest island in Micronesia. The
undersea terrain features mainly sloping reefs. The southwest features a
broad bay. Steep walls along the c1ifflines and outer reef si opes fall quickly
into a blue abyss. The protected harbor
is full of patch reefs and shipwrecks
and is diveable virtually year 'round.
The economy is highly dependent
upon tourism (more th an 1,400,000 visitors per year).
Climate
Guam's climate holds little in the way of
surprises. It is uniformly warm and tropical ail year. Dry season and trade wind
season runs from late December to
May. June through September features
calm seas and little breeze with scat-
tered daily showers. Strong rains are
usually in October and November. The
windward or eastern side of Guam is
most accessible during the summer
months, as are the far offshore reefs.
The seas are normally glassy calm and
fiat. The western side of the island,
especially the Agat Bay and points
south , is normally protected most of the
year and good for diving. Visibility is
affected by runoff, so rainy season
months mean lower visibility. Tides do
not vary greatiy on Guam but visibility
ail over the island is best at high morning incoming tide.
Water here is tropical (average about
80 degrees F) and only a dive-skin is
normally necessary for warmth and protection from abrasions or stings.
Getting There
Getting to Guam is not a problem.
Major carriers serve Guam daily from
ail over the Asian region , Oceania and
the U.S. Distances by jet are approximately 3 hours from Tokyo, 3.5 hrs.
from Seoul, Manila and Taipei, 4 hrs.
from Hong Kong, 7 hrs. from Beijing, 8
hours from Sydney, 9 hrs. from Hawaii,
and 13 hrs. from Los Angeles and 14
hrs. from Frankfurt.
Guam's main carrier is Continental
Micronesia, a subsidiary of Continental
Airlines. International airline carriers
service Guam's new $50 million air terminai with connections to most major
cities .
Getting Around
, It is best to rent a car while visiting. Ali
of the major rentai agencies are here.
