About this site
Bianca lies off the northern tip of Sulawesi in the Bunaken-Manado area of North Sulawesi, Indonesia, along the coast facing the Bunaken Marine Park and the Celebes Sea. Dive operators in Manado run day trips out to sites along this stretch of coastline and around the nearby islands. It's rated a beginner dive, and divers have reported frogfish, mandarinfish, mantis shrimp, nudibranchs, and tuna here, making it a good spot for muck-style critter hunting alongside the odd pelagic sighting.
