  • Possible dive sites:
  • Hot Rocks, a mix of sloping sand and coral formations. At depth, we find gorgonian fans with pygmy seahorses and black coral bushes. There is also a small cave where lobsters can be found. In the shallows brightly coloured neon anemones “pop” against the dark sand and provide a superb subject for underwater photographers. Bubbles coming from these and in the shallow waters provide a distraction during safety stops. 
  • The Estuary pygmy seahorses can be found clinging to the polyps of sea fans along the reef slope and a stunning hard coral garden is great for finding scorpion fish and leaf fish, whilst the sandy patches in between the reefs are a fantastic place to spot sawblade shrimp and a wide variety of nudibranchs.
  • Techno Reef the dark volcanic sand is dotted with green, orange and yellow “black” coral bushes and enormous red barrel sponges, home to ghost pipefish, long nose hawkfish and pink squat lobsters. 
  • Castle Rock currents sweep by this offshore pinnacle in Gili Lawa Laut and white tip reef sharks and trevally can be seen corralling the neon fusiliers. Schools of surgeon fish swarm over the corals and large barrel sponges, whilst huge Napoleon wrasses take an inquisitive look at the divers.
  • Crystal Rock, next to Castle Rock in the bay, this site has 2 pinnacles both offering superb shark action. Eagle rays are frequent visitors and dolphins have been known to make an appearance. White tip reef sharks are often found resting under table corals and common octopus put on superb displays allowing the cautious diver to approach. Currents are to be expected.
  • Shot Gun, typically a fast-paced drift dive, we spend time in the coral garden with soft corals & sponges, before reaching a deep ravine in the reef seeing schools of snapper moving in ever tighter formations. After which you can descend into the fish bowl, where manta rays like to hang out, before the “shotgun” currents push you over the reef and through the channel to the waiting dinghies. Stay close to your buddy and enjoy the ride! 
  • Dragon Besar/Wainilu, hidden amongst the rubble at this shallow site, divers can find mandarin fish and picturesque dragonets as well as frog fish, piefish and pygmy cuttlefish. Dive at sunset to observe the mandarin fish as they flutter up from their rubble home to mate.
  • Tiga Dara /Three Sisters, formed of 3 pinnacles rising up very close to one another. Covered with soft corals each pinnacle is a haven for macro creatures including frog fish and nudibranchs. 
  • Secret Gardens this sloping reef is another superb night dive spot with plenty of crustaceans, mollusks, 
  • Makassar Reef is not too scenic at first sight, but it happens to be a favourite hang-out for manta rays and other rays, so it is definitely worth a visit.  
  • Manta Alley - Channels form in the rocky reef wall and it is here we can hook in and watch graceful manta rays gliding about in the current, being cleaned. They make it look so easy, however strong currents can persist at this site and guests are advised to bring reef hooks. Surgeon and trigger fish as well as schools of jacks can all be seen here as well. Certainly, the mantas steal the show when they are in town, with up to 30 being seen, though groups of 5 or 6 are more common.
  • Pink Beach a shallow sheltered reef that is perfect for a night dive with superb macro sightings from flamboyant cuttlefish, hairy frogfish, octopus and bobtail squid to the barely there skeleton shrimp, Pegasus sea moths, crocodile fish and snake eels.  
  • Guests will have the opportunity to venture ashore on Komodo Island to take a guided walk with the rangers through “Komodo Dragon Territory”. 
  • Cannibal rock a large pinnacles with some of the most diverse marine life in the region. Frog fish, pygmy sea horses, mantis shrimp, epaulette sharks, turtles, a plethora of nudibranchs can all be seen at this site.
  • Yellow Wall, the steep reef wall is covered with yellow soft corals, nudibranchs, orangutan crabs, turtles and octopus. 
  • The Boulders is covered in colorfull chrinoids, soft corals and sponges. This is the place for hunt nudibranchs and crustaceans
