Dear Reader:
I’m a Cozaholic. I’ve taken three dozen trips to
  Cozumel in 33 years and still I’m compelled to return. For
  me, there’s no better season than spring; after El Nino and
  before hurricane seasons, it is not yet too hot or humid.
  Days are usually sunny and seas calm.  
I can depart from Baltimore in the morning and be
  absorbing nitrogen in Cozumel waters by early afternoon.
  It has the Caribbean’s best drift diving at the best
  value. Any diver can locate digs and food to his liking.
  Accommodations vary from the high-end InterContinental
  Presidente Resort and Spa, rebuilt after Wilma in 2005,
  to inexpensive places downtown. Eateries range from the
  upscale Wynston and La Cocay to mom-and-pop places serving
  delicious, cheap “comida corrida.” And there are the
  friendly attitudes, variety of dive sites, and generally
  excellent weather and scuba conditions.  
Clearing the airport in April was a breeze, less than
  25 minutes. The drive to town was 10 minutes, although it
  can be a half-hour for those staying in the south. Just
  three hours after I landed, I was backrolling into 80-
degree water for a meandering swim-thru at Palancar Caves.

 Surface interval at Playa Paradise | 
With visibility well past 100 feet, it’s a good place for
  intermediate divers
  to get introduced to
  walls, swim-throughs
  and openings formed
  by the fusion coral
  heads, and Wilma
  exposed even more.
  I entered several
  openings that deadended
  but there
  was ample room to
  turn around easily.
  Upon emerging from
  a swim-through, I
  spied a sizeable black grouper and green moray engaging in
  cooperative hunting.  Eyeing me suspiciously
  lest I try to horn in, they soon got back
  to business.

The next dive was at Tunich, the
  Mayan term for a beheading stone. This
  site consistently delivers a rollicking
  roller-coaster ride and an odd wicked vertical
  current, and it didn’t disappoint.
  I shot past a tawny-toned, six-foot nurse
  shark festooned with remoras. As I floated
  north, a massive crab claw protruded
  from cement coral below me. A giant green
  parottfish, the color of corroding copper,
  chewed up the coral as it bullied its way
  down the reef. A fine first day of scuba.  
I dived with Liquid Blue because of its excellent customer service and orientation
  to more advanced divers. They had me diving before most of the Cozumel fleet had even
  gassed up. They also provided Worthington HP steel 120s and a willingness to visit
  more distant and challenging sites. The owners are Michaela, a pleasant but serious
  businessperson originally from Colorado, and her easygoing Mexican husband Roberto who
  likes to laugh and loves to dive. The Bonita Luna and Tara II were shaded and uncluttered
  with a small storage space beneath each seat. Having once been stranded off the
  far Yucatan when the engine on a single screw craft went south, I preferred the Bonita
  Luna as she had twin outboards.  
After my first day’s diving, I repaired to the Suites Bahia and my balcony room
  for $55 per night. It’s a block away from Liquid Blue’s shop, several blocks south of
  the main plaza, and just off the waterfront drag. Suites Bahia is a small, basic place
  but spotlessly clean. I had two large beds, a tiled bathroom, desk and a large closet
  with overhead storage. The small kitchen had a mid-sized fridge, sink and electric
  stove, but no cookware or utensils. The price included a modest continental breakfast
  but it wasn’t available until 7 a.m. so I usually missed it due to Liquid Blue boats’
  early departure times. There was no bar or restaurant, and the only common area is the
  small lobby with a TV, vending machine and free Internet service.  
Everything a diver needs is right outside their door. Within a block were two
  dive shops, the American Discount Drug Store; a convenience store for snacks; a boutique
  eatery named Sorrisi that served a medium cup of gelato for $5 and wood-oven
  pizzas starting at $11; and a Pizza Hut for more pedestrian tastes. But I dined at the
  small loncherias, chicken and ribs places and taquerias that dot 30th Avenue east of
  downtown, where turistas mingle easily with locals. Nine assorted tacos and two orange
  sodas at El Pique (across from the old San Francisco market) set me back $10 with tip.
  Compare that to Wynston, where a small green salad with a vinaigrette dressing runs
  $5, and chicken Dijon with rice and grilled vegetables fetches $16. But being perched
  on top of the El Cantil Norte condos, Wynston does have a boffo view. And I must admit
  my most memorable meal was a Caesar salad, mixed seafood pasta fra diavolo and a nice
  bottle of red wine at Prima, a longtime favorite, for $25.  
I’ve never been a big fan of the storied Barracuda Reef because its visibility is
  sometimes so-so and the wicked, vertical currents can deplete gas in a hurry, but on
  this trip I enjoyed it thanks to the mild current and primo visibility. A big spotted
  eagle ray cruised the wall and allowed a long, close approach. So did several hawksbill
  turtles, one of which was munching a large hole into a barrel sponge. I drifted
  across an impressive aggregation of porkfish, schoolmasters and mahogany snappers,
  many sporting mating colors and shades, as if overcome by a spring fever of pheremonal
  frenzy. For surface intervals, I relaxed on the beach at Playa Azul, tranquil and
  pleasant although much of its sand had been Wilma’d away.  
San Juan in the north, a longtime favorite, reminded me why Cozumel is synonymous
  with drift diving. It’s a mid-depth reef with excellent visibility, and its vigorous, steady current let me cover lots of ground. Pre-Wilma, San Juan
was loaded with hawksbill turtles, free-swimming morays and carpeted in vibrant
coral but sadly is now a ghost of its former self. Finger corals now lay in skeletal
heaps and only nascent algae regrowth peeked out. The high point was several
triggerfish going about their mating and nesting behavior, oblivious to the death
lying below them. Cozumel used to have a few nice snorkeling sites but they’ve
also been badly damaged by Wilma. However, Dzul Ha, a small beach club south of
the InterContinental Presidente, and Parque Chankanaab next door are the good bets.
Liquid Blue offered two morning dives and one afternoon dive. The boat left
  between 7:30 and 8 a.m., with the first dive starting at 8:30. I backrolled in for
  my dives and got back in the boat via side ladder. Surface intervals were at one
  of the beach clubs. After the second dive, it was back into port for lunch, then
  the afternoon dive at 2 p.m. They supplied me with a mesh bag with my name on it
  for storing and toting gear. The crew set up my gear daily and rinsed and stored
  it each evening (except for wetsuits). With the exception of a very few dive operators,
  tank fills on Cozumel are done at a central facility; mine averaged 3,000 psi.
  Bottled water and big towels were onboard, but divers had to bring their own extras.
Liquid Blue affords divers lots of freedom. Each day, they asked where I’d
  like to dive. Once divemasters Jorge and Roberto were satisfied with my competence
  and trustworthiness, they went along with relatively extreme dive profiles
  and pointed out great photo ops. This meant I could do deep sites and get profound
  perspectives on sites normally dived at shallower depths. Instead of the typical
  120-foot depths at Maracaibo Deep, I once dropped to 200 feet. Santa Rosa Wall was
  far better at 150 feet than at 90 feet. That my dive buddy and I were the only
  customers for four of our six dive days only added to the feeling of freedom and
  personal attention. However, even on days with more divers, there was still plenty
  of space. 
Bright and early another morning, I wafted over Columbia Deep, a dive typically
  done at 70 to 100 feet that boasts massive coral heads rising 70 feet from the
  sea floor. There, I was stunned by an unanticipated display of sponge spawning.
  Bowl and basket sponges gave off smoky plumes of gametes. Barrel sponges, resembling
  top-loading washing machines overfilled with detergent, positively splooged.
Snow-white spawn churned, frothed and spilled into the current. Spectacular. 
 Surface interval was on the southern
  end at Playa Paradise, which now
  runs together with Playa San Francisco
  and a new Carlos ‘n Charlie’s to the
  north. The beach clubs have been overwrought
  for the cruise trade and lost
  their rustic charm. For example, the
  traditional palapa at Playa Mia (formerly
  Playa Sol) was replaced by an
  outlandish contraption resembling a
  mutant bovine udder. Cozumel is working
  diligently on becoming tacky, but
  blessedly still has a long way to go
  to catch up to Cancun.

Back in the agua, Dahlila, a
  low-profile shelf reef I dived at 40
  feet, was still scoured and silted
  from Wilma. I hoped to find Cozumel’s
  splendid toadfish here, but not this
  time. I was amused by a pair of spotted
  scorpionfish locked in an obviously thorny relationship. Here also was my most
  salacious sighting -- three flamingo tongues extending their hermaphroditic gear,
  finding home and forming a ménage à trois that lasted longer than my gas.  
On this dive, my first stage sprung a leak, then my dive computer flooded and
  died. Liquid Blue provided replacements, did repairs on the spot and didn’t charge
  me a peso. Not surprisingly, a small, personal operation with oversized tanks and a
  willingness to go to the most distant dive sites at no premium charged more. While
  most Cozumel dive outfitters charge $60 to $75 for a two-tank morning dive, Liquid
  Blue commands $85. Nitrox, averaging 36 percent, was $12 per cylinder. Money well
  spent. 
Diving the distant sites on Cozumel’s eastern side requires a boat with enough
  fuel to go from west to east and back, and a crew knowledgeable about the sites.
  After several years of surveying, Aldora Divers now offers daily excursions for
  small groups, conditions permitting, as does Liquid Blue. I have dived the east side
  several times, although not with Aldora on this trip, and found it ho-hum compared
  to the western sites. However, it did provide my only Cozumel hammerhead sighting,
and was a change of pace with its gradually sloping bottom and rocky formations. 
Since my visit in 2006, Cozumel topside has bounced back with a vengeance, bigger,
  flashier and more expensive. Underwater, delicate life such as long tube sponges,
  sea fans, thin lettuce-leaf corals and leafed algae are making a slow comeback.
  Silting is evident but reduced. The fish life is improved but some notables
  remain either in short supply, such as trumpetfish, or missing in action like slender
  filefish. Return divers may lament the hurricane damage but will also find new
  scuba joys, like new swim-thrus. Newcomers should not be disappointed -- it’s still
  boffo diving. The plankton-rich currents continue to assert their regenerative powers.
  While la Isla Cozumel was down for a period, she most assuredly is not out.
  There’s magic in the water.
