Dear Fellow Diver,
About a three-hour drive and a six-mile ferry crossing
  from Cancun is a tropical little Mexican island where
  restaurants serve pasta and pizza, and chips and salsa are
  almost an afterthought. The small dusty village on the
  island of Holbox (pronounced ólbosch) isn’t on anyone’s
  itinerary, save for a few Texans and a handful of Italians
  who, for reasons only they know, have settled there. The
  central plaza features a Spartan basketball court, a small
  white cathedral, and a few vendors. Each evening, someone
  pulls the church bell rope to send riveting chimes through
  the quaint village.Palm-thatched huts, some without
  plumbing, contrast with brightly painted block homes.
  Lobster and squid fishermen comprise most of the 800 inhabitants,
  few of whom speak English. Locals walk, bicycle,
  or use golf carts to navigate unpaved streets. It’s hotter
  than hell, and just as humid during the summer (90+F
  degrees), and mosquitoes outnumber the residents. And, for
  as long as anyone can remember, the fishermen have tolerated
  the scores of thirty-foot fish that ply their waters in
  July and August, just making sure to keep alert so they
  wouldn’t capsize their small craft. Besides, “Mexican
women are winky-winky about whale sharks,” I was told. 
An Eritrean woman by birth, Ornella Alemanni isn’t
  winky winky. Years ago, Onny married an Italian named
  Carmelo Alemanni. While vacationing in Kenya, they went diving
  in a popular destination for Italians, the Malindi Marine
  National Park, where they had exciting whale shark encounters.
  Years later, traveling from their home in Italy, they
  visited Holbox, eventually returning to open a waterfront
  posada with eleven thatched roof huts that they named
  Mawimbi. Recognizing the value of the scores of whale sharks
  that came to feed on upwellings of plankton each summer, Onny
  began taking a few tourists to view them on her 25-foot
  “launcha.”  Soon, fishermen who couldn’t even swim were selling whale shark trips to the tourists and now,
just three years later, it’s on the verge of being
discovered. In fact, as an Undercurrent subscriber,
you’re among the first to know, because
no one else has covered this phenomenon.

just three years later, it’s on the verge of being
discovered. In fact, as an Undercurrent subscriber,
you’re among the first to know, because
no one else has covered this phenomenon.
In August, three friends and I visited
  Holbox, and I was overwhelmed. Each morning at
  7:00 a.m., I walked 25-feet across a white sandy
  beach from my thatch-roofed hut. Wading knee-deep
  into the water, I climbed over the gunwales and
  into Captain Miguel Vega’s small launcha Buena
  Onda, (“everything is good”). Our first stop was
  the pier just minutes away, where officials of the
  Yum Balam Reserve check each outgoing boat for its
  permit (every boat must have a licensed captain
  and a certified guide; 32 boats were granted permits,
  but only 12 are active) and verified that
  passengers were wearing life jackets (which we
  doffed once out of eyesight). Miguel Vega then
  revved up his single 150 hp engine to speed 40
  minutes south along the beach, then turned east
  for 20-minutes into the Gulf of Mexico. Using his
  hand-held GPS, he homed in on the coordinates
  where the whale sharks tend to congregate, joining up with ten other small boats carrying
  off-the-beaten-path tourists who paid $80US in the plaza for a “tiburon
  balleña” tour. Our guide Juan reminded us of the rules (written last year because
  people were grabbing the whale sharks and speeding boats were frightening them): no
touching, only two snorkelers in the water at once, and only one boat per whale shark. 
Suddenly, excited hoops and hollers echoed across the water. The surface
  boiled, while as many as sixty whale sharks, moved slowly, mouths agape, through
  the plankton rich waters. Entering the water directly in a whale shark’s path, I
  peered into its approaching mouth. A few feet away, its eyes appeared to check me
  out (though that may be anthropomorphic). Some fed in circles, giving me a second
  or even a third encounter, where I could see attached remoras dining on parasites.
  Schools of sardines, a frenetic bait ball breaking the surface, gobbled anything
  escaping the gaping mouth. Cobia, playing the roles of pilot fish, kept pace with
  the shark’s strong strokes.  
Two of us would slide into the 79-degree water with one or two whale sharks
  to observe and photograph them. Visibility ranged from 25-30 feet, enough to give
  me a great view, but not enough to capture the shark’s full length with my digital
  and video equipment. I made at least half a dozen entries, lasting up to fifteen
  minutes each. As two of us came out, the mate helped us up a side ladder as the
  boat idled. We never had to wait to find the next whale shark.  
Viewing the whale sharks from the boats was almost as exciting. It was
  thrilling to watch my buddies share this incredible experience. “Swim to your
  left or right,” I shouted, if I spotted a shark heading in their direction or one
  they could intercept.  
As comfortable as the polka-dotted creatures -- the locals call them “dominoes”
  -- appeared (they were barely moving), their strong bodies swept through the
  water faster than I could fin -- the current from their sweeping tails often pushed
  me forcefully through the water. After a tail hit my buddy’s leg, she wore her
  bruise like a badge of honor. One whale shark snuggled along the side of the boat like it wanted to be petted -- could
I resist giving it a gentle pat?
When the afternoon wind picked
  up, the plankton descended deeper
  and the dominoes followed, so we
  returned to shore. The next morning
  we departed earlier to beat
  other boats, but, damn, the sharks
  were gone! When other boats
  arrived, we all fanned out in
  search of them. Miguel speculated
  that they might have headed south
  toward the uninhabited island of
  Contoy, a bird sanctuary (flamingoes,
  roseate spoonbills, cormorants,
  pelicans, ibis and herons).
  A seamount that rises to a depth of
  5 feet five miles north of Contoy
  also attracts the whale sharks.
  But we had a problem. We didn’t
  have enough gas to make the hour
  round trip. When Miguel said we
  could chance buying fuel from a
  fisherman, without hesitation we
  said, “vámanos,” let’s go!  
As we headed south, the other
  boats followed. Soon we were again
  surrounded by whale sharks, so many
  we could have floated in the water
  and waited for one to swim by. We
  were now 48-miles from Holbox.
  Since we were flying to Cozumel at
  3:00 p.m. that afternoon, around
  noon we sadly departed. Luckily a
  fisherman’s gas barge was near the south end of Isla Holbox. Siphoning gas into a
plastic container, Miguel passed over some money and refilled our nearly empty tank. 
My whale shark experience was clearly worth “roughing it” in Holbox. At the
  Mawimbi, only one room is air-conditioned. Onny has no confidence in air conditioning
  because Holbox’s generator frequently shuts down. That’s a problem for the
  few air-conditioned hotels, because some don’t have windows that open. Mawimbi has
  the benefit of gentle ocean breezes. Its thatched roof huts have a rustic charm,
  twin serape-covered beds, but no amenities other than small refrigerators, but the
  place is immaculate with tile floors, wooden beams, and large bathrooms with painted
  ceramic sinks. And the price is right; $50-90/night, and all rooms were taken.
  (A word for the wise: reserve well in advance).  
None of the restaurants is air-conditioned. At Cueva del Pirata, across from
  the plaza, we sat at a table along the dusty road to enjoy the evening breeze.
  The food was okay. Around the corner is Villa Zapata, an upstairs restaurant that
  also serves Italian food. Across the plaza was a busy pizza place. Oddly, the
  Ringling Circus was in town. Tents had been set up next to Mawimibi, so after
  dinner I listened to blaring techno-music before drifting off.
While one can easily drive their ferry to Holbox, we had arranged a six-passenger Aero Saab charter
  plane for $1200 round trip
  from Cancun. We were to
  be met outside customs,
  but when no one showed, we
  hauled our gear about a
  quarter-mile in the heat
  to the General Aviation
  terminal. Though we had
  explained in advance that
  we each had 100 pounds of
  luggage, the pilot took
  one look at our dive bags
  and said they were too
  bulky to fit in the baggage
  fuselage of our single
  engine Cessna 206. We
  rummaged through our baggage,
  took what we needed,
  and sent the remainder to
  our next stop, Cozumel,
  and the Hotel Cozumel
  (Terrible place; the rooms
  are dirty and mosquitofilled,
  the staff has no
  notion of service, and the
  food is inedible. The
  hotel is no longer listed
  on any website so it probably
  was going out of
  business.). Thirty-five
  minutes later we landed on
  the 2000-foot dirt runway
  in Holbox, where a golf
  cart “taxi” met us. We
  spent two days with the
  whale sharks, just enough, I think, making it a nice extension for any trip to the
  Yucatan. The airstrip was only a few minutes from the hotel. On the way out, our
  taxi driver toured the village and was headed to the ferry landing before we
  reminded him we were headed to the airport. He had never been there.
