instructor, and guide, Bil Phillips. Originally from Canada, Bil is one of the best known and most accomplished underwater cave explorers around.

A true pioneer in the region since 1996, he has logged over 4,200 cave dives and personally explored and mapped more than 150,000 feet/45,700 meters of previously undiscovered water-filled passages. He has been a key explorer in no less than 35 underwater cave systems. In recognition, he was elected to The Explorer’s Club of New York as a “Fellow International” in the year 2000.

Bil’s efforts and knowledge have benefited scientific research in the areas of Hydrology, Biology, Water Chemistry, and Geology. He has also contributed to the field of Archeology by partnering with the Instidudo Nacional Anthroplologia e Historia (INAH- Mexico's Department of Archeology) to analyze prehistoric artifacts he and his colleagues discovered.

Due to his vast knowledge base and communication abilities, Bil has been invited to participate in a number of video documentaries on cave diving. He was even featured and interviewed in the History Channel documentary, “Magellan’s Lost Fleet” filmed in Patagonia, Argentina.

Highly respected by his colleagues, Bil has influenced standards in dive education and safety. He has written articles on technical diving and taken leadership roles in several diving agencies and associations.
Bil’s passion for exploration and conservation of the Yucatan caves is matched only by his enthusiasm for training and guiding others. This enthusiasm is undeniable to anyone who has spent time with him. The hundreds of students Bil has instructed have witnessed his ability to tirelessly pursue detail and safety, yet keep the learning experience enjoyable.

Bil Phillips doesn’t just talk about the history of cave diving in the Yucatan. He is part of it.
