Is it possible to dive Boka Onima inlet? Is the current strong?

Yes, you can dive the inlet and out on the reef. But, we really picked a very, very calm day. There was a current running that pushed us away from the 'cut' that day. We did surface out there and found that we really couldn't see the inlet so we didn't go far. The best thing I can say was the bottom outside the inlet resembled diving at the very northern tip of the island - pretty barren. The vis inside the inlet wasn't all that good even when it looked good from the top.

It is not a really good place for inexperienced divers. Please use extreme caution.
