About Fathom Five Divers
Fathom Five Divers is a Kauai-based dive operator located in Koloa, Hawaii, offering guided snorkel tours, shore dives, boat dives, and introductory SCUBA experiences. The company focuses on small-group instruction, personalized attention, and high-quality equipment to help guests explore Hawaii’s marine ecosystems safely and confidently. Trips range from guided snorkeling at Koloa Landing to multi-tank boat dives and specialty excursions exploring remote sites such as Niihau, the island commonly referred to as the "Forbidden Island."
Instructors and guides provide pre-dive briefings, equipment support, and situational guidance tailored to varying skill levels, from first-time Discover SCUBA participants to certified divers seeking multi-tank adventures. Fathom Five’s boat operations include a custom approach to Hawaiian waters, with a noted 6-pack boat operation used for many boat dive trips and access to numerous local dive sites.
Safety protocols, clear briefings, and condition-based decision-making are emphasized across shore and boat programs. Discover SCUBA options state a lower age limit for participation, and many shore dives are described as suitable for divers of all skill levels. Tour offerings include daylight and twilight/night options, shore and boat formats, and both single- and multi-tank schedules. Visitors looking for guided snorkeling or structured dive experiences in Koloa can choose from a diverse set of trips matched to skill level, time available, and interest in local marine life and topography.
