Manem islet and Numfor island are not famous among scuba divers not because there are no coral reefs but mainly because this region is lack of promotion. When I was traveling around the islands I could easily conclude that they are very potential destination for scuba divers. In addition, the tropical rainforest the covers the islands have high density of birds species.
If you are interested in visiting the island, you can contact me, Charles Roring, via my e-mail: firstname.lastname@example.org. I would be happy to be your guide. If your budget is tight, I suggest that you bring bicycle so that you can save a lot of money while traveling around. Recommended beaches in the Numfor island that you should visit are Samido and Asaibori.
