i would rate Togian a bit better than north sulawesie, but still depending what you call north sulawesie, as there is different spots, of course it is not possible to compare with Lembeh as there is no muck diving in Togian...but definitely Togian has less fish than raja rapat ( but where is there more fish than R4 ?) . the coral at the dive site is in very good shape, of course there is a lot of bomb fishing by the past and some area are completely destroy, but it is the same ALL OTHER INDONESIA, after it all depending how the dive center care for you to not see the destroy area or no, sometime it is a pretty difficult job...i call this surgical diving : meaning being very precise on where to start the dive, where to end , where to pass a certain depth to avoid a damage area ect..and Togian is a lot about that , Una Una has the best diving, including the barracudas...Worth the effort : yes !!! , the atmosphere is very relax at the resorts, very beautiful top side scenery, far from everything..i would stay few days in Una Una and few days in Kadidiri, other places does not have good dive sites close by...
i still must be the person with the bigger number of dives in Togian after working 3 years in Kadidiri and 3 years with the Wallacea dive cruise ( Togian and Banggai where their first destinations for years )...
