Dear Fellow Diver:
My dive at Lionfish Wall started as a real drag: once all ten divers had backrolled
  into the water, our boat towed us through the half-knot current for what
  seemed like forever. I finally got to drop the line and start descending. But I
  wondered: geez, couldn’t they have dropped us closer? Then, when I reached 80' and
  caught a glimpse of the fish life along the 30' high wall, my thoughts fled like
  schoolkids when the bell rings.  
The first thing to catch my eye was a flowing blue curtain, a huge, dense school
  of blue-lined snappers. Peach and Bartlett’s anthias and big scale and bronze
  soldierfish swam nearby. Beside them were lemon peel and flame angels and small
  schools of eye-striped surgeonfish in the undercuts. This is the kind of worldclass
  diving I was expecting. We’re deep.  We have some current, some verticality, a
  little excitement. I got so absorbed in taking pictures I didn’t notice I was alone
  until I looked up and couldn’t spot a diver within my 80' visibility. I was running
  low on no-deco time, so I moved above the
  wall and swam over the sandy slope, looking
  for shallower reef. It was almost as interesting
  as the wall, with big schools of
  rainbow-runners circling me and several 2'
  yellow-margin triggerfish carrying rocks in
  their mouths, apparently building nests. I
  surfaced after 50 minutes and the dive boat
  picked me up 5-10 minutes later. The other
  divers were excited because grey reef
  sharks had been circling beneath them, one
  of many unexpected bonuses of Christmas
  Island diving.

  Island diving.  
Christmas Island’s location, smack-dab
  in the middle of the Pacific, might conjure
  up images of pristine tropical paradise, but
  what I found on this barren atoll were huge dumps of rusting machinery and small
  mountains of 55-gallon drums. Though there are miles of gorgeous beaches, there’s
  little indigenous culture. The island has long been a fisherman’s Mecca, but it’s
  only begun to attract divers in significant numbers. That’s surprising, because for
  a “remote” location, Christmas is an easy trip; by air, it’s only three hours from
  Honolulu. 
I’d heard enough about Christmas’ serious coral bleaching during the 1997-98 El
  Niño that I was apprehensive about what I’d find during my May trip. Fortunately,
  the hard corals seemed to have recovered with only a few spots of bleaching. And
  the fish life? Well, nearly every species that has made it from Micronesia to Hawaii
  is also found in the Line Islands (the Pacific island chain of which Christmas
  is a part). Surprisingly, I also found many species listed as having a range from
  the Red Sea to New Guinea.  
Although much of the diving lacks drama, this is about as close as you can get
  to unspoiled, virgin territory. It’s comparable to the central and southern Red Sea
  and certainly a big notch above Hawaiian diving. No walls plunge to infinity, but
  Christmas has great fish species diversity.
Kim Anderson, the island’s only dive operator, has been on Christmas since 1992.
His youthful enthusiasm, boyish smile, and friendly, outgoing nature belie his age.
He met us the first morning and wasted no time gathering our group and starting his
orientation. Then we loaded our gear into the two six-passenger trucks Kim left for
us to drive between our hotel and Dive Kiribati’s shop on the island’s leeward
side, 15 miles and a full 30 minutes away.
My dive group had been assigned for the week to the Spinner with its operator and
  divemasters, usually Randy and Yoshi, both of them new to the area. Randy, with scruffy
  beard and graying hair, was friendly and experienced, but he lacked practice at finding
  the sites. Sometimes wasn’t exactly where he thought he was. Yoshi was a knowledgeable
  Japanese marine biologist, though I had trouble understanding her accented English.
  While Kim clearly knows the sites, I only dove with him a couple times, though he answered
  my questions later.  
Dive Kiribati takes reasonable
  precautions but doesn’t spoil the
  experience by hovering over
  people. Though dives were usually
  55-70 minutes, time limits were
  seldom imposed, and they never
  provided a dive profile. Most
  sites were 30-65', though some were
  100' or deeper. My group of nine
  U.S. divers had been pre-booked for
  three dives a day (17 over the
  week). Although I’m sure we could
  have controlled where we went, we
  had no idea where that should be,
  so we went with the flow.  
Dive Kiribati uses two unique
  35' outrigger dive boats -- 4'
  wide with a 15' pontoon-like outrigger.
  A wide platform between
  the boat and outrigger provided
  room for half a dozen people to
  stretch out (although the platform
  became slippery when wet). Another
  six divers and the crew could sit
  on the ten-inch wide gunwales on
  the main hull, shaded by a tarp.
  Each boat had a sturdy ladder, a
  cooler with icepacks, drinking
  water, and a container of fresh
  water large enough to soak three
  cameras. On most dives the boats
  held ten, but they were roomy
  enough that we never had difficulty
  finding somewhere shady to
  sit or lie down. And lie down we
  did, since we were on the boats
  from 8:30 a.m. till 4:30 p.m.,
  including 60-90 minute surface
  intervals.  With no formal break
  for lunch, people snacked whenever
  they wished. We had sandwiches each of us had prepared after breakfast
from the lunch buffet table: fresh bread,
jars of peanut butter, jam, salami, bologna,
reconstituted ham, sliced onions,
tomatoes, lettuce (at first), and cheese.
Fruit was usually just oranges and apples.

My lodgings at the Captain Cook Hotel
  were comfortable but hardly a trip highlight.
  The place is funky but quaint, a
  single-story "Motel Six" accented with
  rock work. The hotel’s two partially airconditioned
  wings hold about 50 guests.
  During my stay they were nearly 2/3 full
  of divers and fishermen.  
I stayed in the duplex bungalows
  nearby. They were South Pacific thatch-roofed but still echoed the hotel’s prefablike
  structure. Mine took a mere stab at ambiance, but I had a sweeping, unbroken
  view of the pounding surf. Though they weren’t air conditioned, in late May the
  rooms were comfortable with the constant sea breeze and a large rotating floor fan
  to keep the air moving at night. Each unit included a large bedroom with either a
  double bed or two twins, small bedside tables, a generous closet with built-in
  drawers, and a refrigerator -- nothing fancy, but clean and decent. The full bath
  had a separate double-size shower enclosure and a toilet room.  
Nonetheless, I prefer wonderful diving to a wonderful room. And Dive Kiribati
  introduced me to three sites that I consider world-class. While the bulk of our
  dives weren’t stellar (they were topographically challenged), Christmas always
  delivered a vast assortment of marine life. The 30-mile Bay of Wrecks is an exception
  to the poor-topography rule. Named for the plethora of square riggers that ran
  aground there in the 17th and 18th centuries, the Bay’s waters have long since
  reclaimed the hulls. The site was about an hour’s drive across the island. Entries
  on the slippery, rocky beach were challenging, but the wall was one of Christmas’
  best. It started at 15' and dropped rapidly to beyond 200', although the best coral
  was from 20-60'. When I reached 25', a dozen calm but curious 4-6' gray reef sharks
  started swimming up to within 2' of me. Deeper, a huge school of immense blackfin
  barracuda meandered 20' off the wall. Solitary, seemingly oblivious 7' white tip
  reef sharks cruised by. The wall itself was full of hard coral and butterflyfish,
  threadfins, and lemon peel and flame angels. I spotted clown triggers doing a mating
  dance, standing on their heads and twirling around. A large school of big-eye
  trevally swirled in a classic vortex at 110'. We doubled back and exited on the
  beach where we’d entered. My legs were so tired that the waves knocked me down
  repeatedly, but the dive was worth it: a world-class dive I’d compare to Blue Corner
  in Palau. Fish life and depths are similar, but here the sharks are close and
  you’re not surrounded by hundreds of other divers. 
At M Spot, a low hill of coral that begins about 30' and descends to a sand
  bottom at 65', a 12' manta passed over the mound several times, swimming slowly
  through the large schools of fish so cleaner wrasses could remove his skin parasites.
  At Eel Site I saw lots of octopi as well as giant, masked, and yellow-lined
  morays in several holes, some five to a hole. The site was like an apartment building
  where residents zipped in and out like dartfish whenever I approached, moving around
  the large moray who was always guarding the front door. On another morning we followed
  a pod of eight spinner dolphins for half an hour. With my mask in the water,
  I held onto ropes tied to the boat’s pontoons as the boat pulled me along. Schools
  of large tuna, turtles, and mantas swam below.
The fishermen were early risers, so
breakfast was served early (5 a.m. till
8:30) to accommodate them. Choices included
cold cereal and milk, coffee,
orange juice, apple juice, scrambled eggs
or omelets, bacon, toast, rice, and homefried
potatoes (which were often
undercooked). At times there’d be pancakes,
waffles, and grapefruit.
Before dinner there was usually time to
  unwind over an Australian Victoria Bitter
  or something stronger, talk about the
  diving, and watch the sun paint the
  evening sky. Since the only edible products
  of Christmas Island are fish, lobster,
  and octopus, it suffers from the
  limited cuisine characteristic of most of
  Micronesia. Fruit and vegetables, like the
  tourists, are flown in from Hawaii. By the
  end of the week supplies had dwindled.
  Still, I found the food acceptable thanks
  to a creative kitchen.  
Entertainment was more exotic: a performance
  or dance with music or drums almost
  every night, sparks of native culture. One
  night we had a beachside luau replete with
  barbecued pig, and afterwards Gilbert Islanders
  in native costume passed out fragrant
  plumeria wreathes and performed
  traditional dances. To close the week, Kim
  brought his family and his divemasters to join us for a barbecue under the stars.  
It’s hard to draw hard and fast conclusions about Christmas. The diving will
  cause one person to rave, another to wonder. I was hoping to be stunned by a panoply
  of fish, and I did see an impressive array of critters I’d never laid eyes on.
  However, some critters were missing: I saw no clownfish and few sweetlips, sponges,
  anemones, soft corals, or gorgonians. Even the diver who’s seen it all will find
  that the diverse fish species make heading to Christmas worthwhile. It’s not the
  spot for wall divers seeking drama or divers who want to photograph weird critters.
  But if you’re tired of overvisited sites and find yourself wondering what they
  looked like at the beginning of time, Christmas fills the bill just fine.
