Dear Reader:
I don’t want to offend my many dive buddies who look
  forward to browsing those Cozumel jewelry shops or eating
  nachos at the same franchise eateries they could find
  in Des Moines, but for me that’s no adventure. Sure the
  diving is good, but I prefer reefs less traveled. So, in
  February my partner and I headed for the Caribbean coast
  of Nicaragua, where the only jewelry sold was strung seashells
  and no one had heard of nachos. My only question
  was whether the diving was any good.

After spending a pleasant evening in a hotel near
  the Managua airport, I was shuttled by the hotel’s van
  for a 7:00 a.m. flight to Big Corn Island, 50 miles off
  the coast. Along with 25 islanders and a handful of travelers,
  I boarded a huge panga and a half hour later I
  stepped onto the beach in front of Dive Little Corn, which
  is owned by the Casa Iguana Hotel, my home for a week.
  Running along the “front side” of Little Corn Island is
  a sidewalk fronted by a few small businesses. The only
  wheeled vehicles on Little Corn, population 900, are bicycles
  and wheelbarrows.
  “Streets”
  are sidewalks
  or dirt paths.
  Once dominated by
  British colonizers,
  the traditional
  population
  of African
  ancestry speaks
  English, though
  some mainland
  “Nicas” have moved
  to the islands.
  While I occasionally
  switched
  between English
  and my bad Spanish, I could have just as well stuck
with English.
 Casa Iguana measures up quite well.
  The staff carried our gear by wheelbarrow
  on a ten-minute trip through the woods
  and hotel vegetable garden to our casita,
  #1, private yet close to the restaurant. I
  had a comfortable bed, low wattage but adequate
  24-hr lighting (115V power available),
  a desk, a clean inside bath, and a private
  outside shower. From the very private
  porch, with chairs and hammock, I viewed the
  wide Caribbean expanse and long empty beach.
  A friendly iguana viewed me from a rafter
  above. The setting, cottage, and grounds
  looked as good as the website advertised. I
  felt safe and welcomed. The island’s three
  police officers enjoy free breakfast daily at Casa Iguana, but I doubt they find
  much to do here but walk around town visiting.

At 2:00 p.m. my partner and I were on the dive shop deck for a briefing so
  thorough I thought the site, White Holes, must be their featured attraction.
  Turns out that the DMs give this kind of briefing for every dive. I waded to the
  boat and ten minutes later backrolled off for my first look at Little Corn diving.
  White Holes (sand holes in the coral) is a shallow formation capped with an
  elkhorn forest (elkhorn is so under threat that the U.S. government may label it
  an endangered species). Two funny-faced clown wrasses were display-fighting in
  a mouth-to-mouth posture. Halfway through the dive, I stopped counting the nurse
  sharks. In the coming days I would see dozens, none more than 7 ft. Besides the
  typical reef residents, most sites were loaded with juvenile slippery dicks, and
  some had beautiful black-on-yellow juvenile puddingwives. I saw eagle rays on most
  dives, but few large food fish, such as snappers and grouper. Perhaps more disconcerting
  was the colorful but heavy algae growth. The cause certainly couldn’t
  be effluent from tiny Little Corn. Could it be the lack of big parrotfish? When I
  mentioned it to the dive staff, I just got puzzled looks.

Elsewhere, the coral looked healthier. I liked My Place and Yellowtail, both
  low-profile patch reef networks with a sandy bottom at 50-60 ft. At My Place I
  watched five big midnight parrotfish (almost the only type of big parrots I saw)
  munching the coral. Pompanos flashed high in
  the water column. A beautiful little goldentail
  moray peeked out. At 15 ft, I was surrounded
  by a bloom of spot-winged comb jellies.  
Yellowtail was similar, but with more
  schools and cleaning stations. I counted six
  barracuda being deloused, most by multiple
  fish, including fairy basslets. I emerged from
  a short swim-through to a wall of French,
  Caesar and sailor’s choice grunts. Midnight
  parrots were joined by queens and the tiny
  pink-on-turquoise blue lip parrot. A swarm of
  bluehead wrasses had broken the defense of a
  male sergeant major and were devouring his purple
  egg clutch. After the dive, I handed up my
  weight belt and BC and climbed a side ladder.  
Although a one-person dive shop has opened
  next door at Delfines Hotel, Dive Little Corn is Nicaragua’s first dive operator, so
many reefs bear monikers of former staffers.
They do three dives a day, using a
panga with tank racks and room for eight
divers. The open boat has no amenities,
but sites are close and intervals are
spent at the beach. They carry a DAN O2
kit. They split us eight divers (there
are fewer in the off-seasons) into two
groups, each under the eyes of one of
their North American divemasters, Tim or
Carron, both competent and agreeable. By
the time you get there, others will have
replaced them, I suspect. Turnover is
high.
 Between dives, they switched aluminum
  80s on the boat, and Tim switched my
  buddy’s high pressure hose without breaking
  a sweat. Rental gear, yes; Nitrox,
  no. They limited dives to 55 minutes.
  (The 82F water kept them pleasant.) The
  DMs allowed divers the option to do their
  own thing but managed to annoy my little
  group when we wanted to do a third dive to a 60-ft site after a second dive to 50
  ft. Oddly, they firmly vetoed this “reverse profile.” After diving, I carried my
  gear up to the shop, rinsed it, and stored it in their secure area.  
After two morning dives, my friends and I would walk down the front side for
  lunch. I liked the cheese empanadas (turnovers) at the next-door Colombian restaurant,
  and the Cuban restaurant was a good choice for lunch, dinner or drinks.
  None of these joints had signs, nor are they needed. One day a norther blew
  through and wiped out diving, so folks fell back on the Caribbean three Rs: rum,
  relaxation, and romance. I took a 15-minute walk to the lighthouse for good
  views of the island, then wandered on trails to the north end, where an eccentric
  German runs a little camp-resort. A 30-minute beach walk gets you to Peace
  and Love Farm and a good Italian dinner; Casa Iguana will radio them to make a
  reservation. Despite the isolation, the island is rather cosmopolitan. The young
  guy who runs the Colombian restaurant is from the nearby Colombian island of San
  Andres, but his parents are from Venezuela and Nicaragua. He was happy to chat
  about Caribbean life, as were Captain Jorge and other folks we met.  
I did one night dive at Buoy (misnamed: there is none). Starting early, we
  saw the grunts leaving the reef in the twilight. After dark, I found a 3-ft turtle
  snoozing in the coral. I cut a wide circle with my light to avoid waking it,
  but the big guy stirred and swam over me. By then the red swarm -- the cardinals
  and squirrel fish -- were rising. A basket star spread wide over a gorgonian,
  and I found three large lobsters, a surprise since the economy is based on lobster
  fishing. On a day dive, hundreds of small bar jacks circled the site. About
  100 mojarra hung motionless over the bare sand, as if in a trance. A ray gently
  pushed off the sand and let me shadow it. This reef has a well-defined halo
  of bare sand, with turtle grass beyond. The 20 ft bare patch marks the limit of
  where the algae eaters will venture from the safety of the reef.  
Sites outside the reef are accessible on calmer days. At Shark Hole, I
  entered a long and convoluted tunnel. Halfway through it, hundreds of glassy
  sweepers parted to let me pass. Forty minutes into the dive, a 6-ft reef shark
  crossed in front and another cruised past the divers behind me, followed by an
  eagle ray. At Tarpon Channel, the stars are apparently hammerheads (the divemasters
  claim it’s a 50/50 chance to see them) though at ten minutes and 70 ft into the dive, my buddy’s pressure gauge blew, so we left the movie before the plot
developed. Captain Jorge spotted us within seconds, so we didn’t suffer a surface
swim. The DM reported two hammerheads. Tarpon Channel, Sueños, Shark Hole and
other windward sites, most of which have nice swim-throughs and overhangs, often
have murky 20-50 ft visibility, which gives the shark’s sensory system an advantage
over prey.
While the Delfines Hotel is clean and air-conditioned, most readers of
  Undercurrent will prefer Casa Iguana and its 13 casitas. The deluxe casitas sit
  atop a low cliff overlooking the reef on the windward side. These are simple but
  comfy, with potable well water from the tap and a private porch, a great place
  for reading. There’s no a/c (but the sea breeze kept it perfect) and no hot shower
  water unless the sun gets the rooftop tank warm (which made it easy to obey the
  “please conserve water” sign). Most electricity comes from wind power, though they
  run the generator (and open the satellite-dish Internet café) each morning. The
  American owners, Cathy Sherman and Grant Peeples, have spent ten years shaping it
  into a genuine eco-resort. What other resort’s website boasts “Ten reasons we may
  not want you to come here,” beginning with “Your favorite travel destination has
  been Nassau, Bahamas.”  
Casa Iguana catches most of their meals (if you go on their fishing boat,
  your catch is dinner), buys local lobster and conch, and grows vegetables and
  fruit in an extensive garden. For a remote resort, the full dinners are excellent.
  Most nights I had fresh barracuda or lobster, prepared in various ways, and always
  fresh vegetables and good desserts. And the inevitable Toña or Victoria beer. The
  breakfasts are plain but plentiful with a half-dozen good choices, all with fresh
  fruit on the side. Excellent coffee is always available.

The guests were an interesting mix of divers and travelers with whom I spent
  evenings in the comfy lodge, imbibing, playing cards, and talking diving. Some
  were off sailboats; others were there to fish. Most were North Americans, a few Europeans. A friendly Irishman was on
a six-month world tour, and an American
was kicking back after serving as assistant
captain on an Aggressor.
After several days of patch reefs
  on a flat bottom, I missed the sensation
  of flying over the deep blue off
  a wall. The deepest site here is Phil’s
  Find, where the reef top is 60 ft and
  the sand floor is 95 ft. As compensation,
  the beautiful cover girl on Paul
  Humann’s Reef Fish, the rare golden hamlet,
  with its black and electric-blue
  face, is common -– I spotted four on one
  dive. The studded sea star, described
  in Humann’s Reef Creatures as a rare and
  undescribed species, is also common. And
  there aren’t many Caribbean spots where
  you can reliably find unchummed sharks in an unspoiled environment.  
Perhaps their top dive is Blowing Rock. Only six divers can make the trip,
  and because I was slow to sign up, I was relegated to more reef dives. However,
  a friend who joined us for part of the week told me: “After a smooth 50-minute
  ride, we arrived at a pinnacle of rocks. On the first dive, we headed to the bottom,
  which slopes from 80 ft to more than 100. The first thing I noticed was the
  sheer number of large fish. Schools of big bar jacks, snappers (including cuberas),
  as well some big midnight parrots and mixed schools of tangs. Diving on the
  coral-and-sponge-encrusted boulders, some of them house-sized, reminded me of Los
  Islotes off La Paz in Baja.
 “On our first dive, three reef sharks suddenly appeared, darting erratically,
  maybe hunting or jostling with each other. I got as close as I wanted under the
  circumstances. We circled the islet on each dive, taking a shallower profile on
  the second. Between dives we spent an hour interval on the boat, where the rock
  pinnacle provided little relief from the swells. The trip back, against the wind
  and seas, was bumpier than the morning trip. This is a dive you don’t usually
  experience in the Caribbean and worth the ride and the $90 (instead of the usual
  $60) for the two dives.”  
When divers sit around the bar, inevitably the talk gets to dive locations.
  When I mention an off-brand place like Cayos Cochinos, Honduras, or María la
  Gorda, Cuba, everyone wants to know more. But I suspect they still book their next
  trip to the Caymans. Most divers want that extra bit of comfort and predictability.
  I’ve never regretted heading in less-traveled (and less expensive) directions,
  and this was a fine trip. So, if you’re an off-the-beaten-track sort of diver,
  happy with a good array of fish, some nice patch reefs, and a bit of an adventure,
  pencil this in. But do more than pencil in Blowing Rock, because that’s one boat
  you’ll want to be on.
