I stayed at La Rascasse Resort and dive with Minahasa Divers (right by La Rascasse). There is the house reef right by the resort where we had excellent night diving (muck diving). We also had a chance to go Bunaken island as well as Lembeh Straits. You can check out my experience at www.vimeo.com/greenturtle and look for the Manado dive videos. Have fun!
