Bitung is the busy port for Manado on the island of Sulawesi. Like other Indonesian ports, it’s interesting just to see what sorts of ships turn up in the port. The narrow strait between Bitung and the island of Lembeh is famous for its colorful sea life, particularly smaller species such as nudibranchs, miniature seahorses and so forth. Manado has ample evidence of its Dutch colonial history, but many visitors are drawn to the remarkable nature preserves such as Tangkoko, where achingly cute, saucer-eyed tarsiers and endangered crested black macaques are the main attractions, along with toucan hornbills. The village of Airmadidi has remarkable carved stone sarcophagi dating from the pre-Christian Minahasan culture.
