Waikiki Sunset Cruise with BYOB & Diamond Head

Dive Oahu runs a tight operation that clearly knows how to show divers and snorkelers an incredible time on the water. The crew gets consistently praised across the board, with Captain Mike, Nacho, Colton, and several others mentioned by name for their professionalism, knowledge, and genuine warmth. People love that the captains share stories about local marine life and Hawaiian culture, and dive masters go out of their way to spot octopuses, nudibranchs, and of course the abundant sea turtles. The boats are well-maintained, gear is in excellent shape, and they handle everything from setup to refreshments so you can just focus on the experience. Popular dive sites include the Sea Tiger wreck and various reefs, with the newer west side charter getting special appreciation from locals. That said, there's a concerning pattern with equipment rentals that prospective customers should know about. Two separate reviews report serious issues getting deposits refunded after renting surfboards, with one person waiting over 20 days despite multiple attempts to contact the company. These complaints stand in stark contrast to the overwhelmingly positive feedback about the diving and snorkeling operations. If you're booking a boat charter or certification course, you're likely in excellent hands based on the feedback. But if you're considering renting equipment, you might want to clarify their deposit refund policy upfront or possibly look elsewhere for gear rentals.
