Wally Siagian is one of Indonesia's sport diving pioneers. He first dove Bali in the 1970s and his long-term knowledge of the island's reefs is unmatched by anyone working today. Originally from Bandung, he moved with his family to Bali in the 1980s and has been guiding divers--chiefly scientists and photographers--for more than three decades.
