Beautiful Rock – an amazing new dive site in Mommon, Indonesia


As group leaders specializing in Indonesia and the Bird’s Head Seascape, Maurine and I are always looking for new itineraries and ways to improve our standard trip routes.  For a number of years we have led an itinerary that starts in Sorong (Raja Ampat) and ends, or round-trips, in Kaimana (Triton Bay).  This journey, however, involves a long, 210 mile, passage between the southern part of Raja (SE Misool) and Triton.  Divers, myself included, never want to spend time motoring when they could be diving, so a stop in the Pisang Islands and another near Mommon (halfway between Pisang and Triton) is usually the itinerary we choose.  There is an outstanding site in Pisang, plus a couple of others that are good, so this stopover is usually a hit for the long transit day.  But until my most recent trip aboard the MV Pindito, the Mommon stopover was, well…other than a visit to the picturesque waterfall…a diving bust!

cMy colleagues at Conservation International suggested that I check out the small islands outside the bay, just west of Mommon peninsula.  There are a few islets in the area, so we thought we’d give at least one of them a try, offering an exploratory dive instead of a visit to the waterfall.  I have done a LOT of exploratory diving (we specialize in developing new itineraries), but frankly most exploratory dives aren’t very productive, and we try to avoid doing many when we have guests onboard.  Now and then, however, we get lucky and uncover a real jewel.

Late last October our group dropped in on Mommon’s outer islands. We chose the southwest corner (ocean side) of the third islet in the four-islet chain.  The reef was average at best, comprised mostly of stormed-dwarfed, low profile hard corals.  I knew this was no prize, but as we swam east, around the southern tip of the islet and headed back north along the east side into the channel between the islet and Mommon peninsula (the mainland), we began to see a few large, soft-coral covered bommies.  The reef was definitely more interesting here.  As we continued north along the east or channel side of the islet, we encountered a giant grouper, then spotted an even giant-er one. The site was hot and becoming even hotter as we swam by a series really big soft coral-covered boulders.  Draped with glassfish and sweepers, these boulders were nothing short of amazing.

Everyone agreed there was no need for further exploration that day. We, happily, decided to dive the same site again before motoring to Triton Bay.  This area begs for more exploration, but for now Mommon has at least one “must stop” dive! The Pindito staff called it simply Batu Cantik (Beautiful Rock)!

Burt Jones and Maurine Shimlock are award-winning marine life photographers whose assignments have taken them around the world to portray diverse subjects including the world’s longest underwater cave in Mexico and nesting sea snakes in Borneo. Their photographs have been published internationally, and Secret Sea, a collection of their photographs, was honored with the Benjamin Franklin award as the best book printed world-wide. Burt and Maurine’s lively and informative teaching style and their “Stop Taking Pictures and Start Creating Images” seminar, which they present on their Secret Sea Visions “Scuba Safaris”, have helped hundreds of marine life photographers improve their technique. Burt and Maurine are renowned “critter spotters” and their images often reveal habits and habitats of creatures many people never see for themselves. In June 2008 they began working with Conservation International as consultants on sustainable marine tourism. Burt and Maurine’s long-term project is to explore, photograph, and to produce guidebooks and website content for the remote and uncharted dive sites around Raja Ampat and the rest of the Bird’s Head Seascape in West Papua. Their guidebook, Diving Indonesia’s Raja Ampat, was released in late 2009. A revised and expanded sequel, Diving Indonesia’s Bird’s Head Seascape, was published in late 2011. The Bird’s Head Seascape website,, launched in June, 2014. To learn more about Burt and Maurine, their images and scuba safari programs visit their website,
