Resorts aside, how do you compare the diving to RA or komodo Dan ?
It’s just as good in different ways. Maratua’s soft coral may not be as diversed as Misool, but it compensates by the massive schooling barracudas (in thousands) that are unique to northeast Kalimantan & Sipadan that I haven’t seen anywhere in Raja Ampat (RA). I’ve been in RA 6 times in the last 8 years. The schooling barracudas in RA may be about 10% that of in Maratua Atoll at best.
So, if you you are there, don’t miss the dive site
Big Fish Country or others call it
The Channel for seeing the schooling barracudas. The site is only 5-10 minutes boat ride from Nabucco Island and it reminds me of Peleliu Cut or Blue Corner in Palau. Be prepared with your reef hook for a quick negative entry & get ready for exciting sites of massive school of barracudas along with sharks, Napoleon wrasses, jackfish. I love the site so much and did it 3 times while I was there for a week. The dive is done during a high tide. So, after you run out of NDL, you just unhook yourself off the reef & drift on to the shallow. Very safe. No drifting into the deep blue water.
The stingless jellyfish in Kakaban are prolific in comparison to that of in Misool or in Palau. The last trip I went to Misool (November 2017), the adult stingless jellyfish there got wipe out, leaving tiny baby ones, according to the ranger there. He didn’t recommend us to visit the place, so we skipped the tour. Same with Palau. The El Niño wiped them out. We also skipped that place when I was there in December 2017.
If you are into seeing mantas like the manta cleaning station in Magic Mountain (Misool) or Manta Ridge / Manta Sandy / Blue Magic in Dampier Strait, you can also see them around Sangalaki Island.
