Dear Fellow Diver:
If you stroll around the scrubby town of Two Harbors
  on Santa Catalina Island, you may feel like you’re in a 60s
  time warp by the music wafting from behind the open-air bar,
  the only bar in town. But it’s not much of a town. There’s
  a hotel, probably last decorated in the 60s, a smattering of
  houses and places to stay for students on field trips, and
  a dive shop smack on the pier where the ferry docks when it
  arrives from San Pedro in Los Angeles Harbor. Two Harbors is a
  two-hour bus ride to Avalon, the town with all the action.

 The Garibaldi anchored in Two Harbors | 
The Banning House, perched on a small hill above town, is
  as comfortable as a shaggy old sweater, but not particularly
  welcoming. When I stayed there, I had Room 8, apparently the
  most expensive in the place because it had a few more square
  feet, a couple of chairs and a porch that doubled as a patio.
  It also had an expansive view of the remote Catalina Harbor
  on the west side of the island, but so did most other rooms.
  Room 4, with a shared patio, might be the best deal in the
  house. Only breakfast was served, a modest buffet with fresh
  fruits, a couple of cereals, little sweet rolls. So lunches
  of burgers, fish and chips, etc., were down the hill at the
  West End Galley. Dinners at the Harbor Reef restaurant were
  a reasonably priced variety of decent pastas, meats and fish,
  with prompt service and a full bar. It was a five-minute walk
  or a hotel employee
  was always willing to
  drive guests back and
  forth. (Occasionally
  a bison or two wandered
  by, their ancestors
  brought to the
  island decades ago for
  a movie but now in
  peaceful retirement.)
  Aside from climbing
  the hills, walking a
  few dusty roads, or
  kayaking, staying here is all about diving -- the best land-based diving
in California.  I’ll let my colleague describe it,
because he has also dived round the island on liveaboard
boats and has a lot to compare it to.

Most of the diving here takes place in and
  around a marine invertebrate preserve just off
  Isthmus Cove on the west end of the island, facing
  Long Beach. Although I’ve dived Catalina for years, I was blown away by the water
  clarity and scenery. Lobsters, eels and other fearless critters posed patiently for
  photographers. Brilliant orange Garibaldis were in my face like border guards. (They
  must know they’re the state’s official marine fish and therefore protected.) Two
  Harbors Dive & Recreation Center, a full service PADI operation, runs a 45-foot dive
  boat, named -- guess what? -- the Garibaldi. It rides smoothly on a catamaran hull, is
  square-ended fore and aft, can hold up to 24 divers, and has a marine head. While THDRC
  isn’t exactly a valet diving operation, the conscientious crew attended to details.  
On the most recent trip, my first dive, at a site called the Sphinx, set the tone.
  Seated on a bench amidships, under the cover of a canvas awning, I set up my tank and
  BCD on an aluminum 80 filled to 2800 psi, which I humped back to the spacious openair
  fantail. Sitting on the deck with my feet on a surface-level swim step, I pulled
  on my fins and divemaster Josh helped me into my BCD and I stepped right in, no giant
  stride required. THDRC offers either guided or individual diving, but the guided tours
  must include all divers. So we opted to dive on our own, following the thorough briefing
  given by Captain Dave. The only glitch occurred when two divers, wearing rental
  suits, were improperly weighted and had to return to the boat. 
My buddy and I swam to a wall forested with bull kelp, where I could sample the
  beauty of the huge leafy vegetation without risking entanglement, or penetrate as deeply
  as I wished. Fog had rolled in so there wasn’t much color underwater, and visibility
  was only 30 feet. At 1500 psi, we turned back and after a leisurely downcurrent kick in
  68-degree water, I heard classical music playing! The Garibaldi crew lowers an underwater
  amplifier to help divers find their way back. Following the sound, I hovered under
  the boat for my safety stop, then kicked up to the three-part swim step. It was easy
  to pull myself onto the submerged center portion, then sit on one of the surface-level
  platforms while Josh removed my tank. After I had stowed my gear, Josh offered me a
  cup of hot chocolate, but no towel -- bring your own. In the 70-degree weather, I managed
to drip dry. 
In mid-October, my group had the Banning House almost to ourselves and with as few
  as two divers, the Garibaldi was virtually a private charter.  On our second day, we
  rescheduled the departure time to 9:30
  a.m., allowing for a leisurely breakfast.
  We also could request specific
  dive sites, so I was able to avoid some
  in the area I consider liveaboard clichés,
  like Bird Rock and Ship Rock. At
  the end of the day, I left my regulator
  and BCD on the Garibaldi, rinsed the
  rest of my gear and hung it on a drying
  rack at the shop. Shop manager Hilary
  moved everything indoors overnight,
  even after our last day of diving -- a
  thoughtful service that let us pack relatively
  dry gear for our trip home.

On my second day, the sun came out
  and visibility improved to 40 feet at
  Parson’s Point, near a campground outside
  the preserve. In bright sunshine, I enjoyed viewing a lush array of kelp and other vegetation. Showy little blue-banded
gobies were everywhere. The Garibaldi deployed a current line but they never dropped
us in a site with substantial current. In fact, they revisited a few sites until they
decided the current was dive-ready.
At Emerald Bay, I stayed above 33 feet to enjoy the play of sunlight on colorful
  gorgonians, with just enough surge to keep things flowing. Streams of bait fish swooped
  by, just out of reach of the photographers who were diving solo. I even spotted a few
  living abalone -- an encouraging find in an area where the tasty mollusks had been
  hunted nearly to extinction in the 80s. They’re still protected in the Channel Islands
  -- for now. Visibility continued to improve to 50 feet or more with increasingly sunny
  weather as we visited sites like Sea Fan Grotto, rarely-dived Eagle Reef and Isthmus
  Reef, occasional home to giant black sea bass, which were out when we came to call.  Conditions were gentle and none of my dives exceeded 75 feet.  
On our final day, we arranged a tour of the University of Southern California
  Catalina Hyperbaric Chamber, reachable by water taxi or kayak from Two Harbors.
  Operations Manager Lorraine Sadler gave us a primer in decompression theory, and then
  led eight of us into the chamber. She secured the hatches and took us down the equivalent
  of one foot underwater. I felt the pressure immediately in my ears, and could
  only imagine what a two-hour treatment at a depth equivalent of 60 feet would be like.
  It was a sobering experience. Hopefully, I’ll be able to enjoy diving Two Harbors
  again without a return trip to the chamber.
