Reef expert and dive master Suzzy Robinson works with small groups (of six or fewer) for Maui Snorkel Tours; she picks that day’s best shoreline site and then provides plenty of unhurried instruction. Robinson is great with insecure or rookie snorkelers. And she knows absolutely everything about every fish you’ll meet.
Various locations in Kihei.
The divemaster will contact you the night before your trip to tell you where that day's excursion will meet.
