I was there in October of 2008, the trip was great. I dove off of Bunaken Island (about and hour boat ride from Manado) and it was spectacular. If you have time, I recommend checking out Tangkoko Nature Reserve too to check up the Tarsier Spectrum (world’s smallest primate) as well as the Black Crested Macaques, it’s a very "off the beaten path" adventure. If you would like details, let me know.
