Experience the underwater wonders of Hawaii’s Big Island with professionally guided scuba diving tours departing from Kona, Hilo, and along the Kohala Coast. The island’s unique volcanic landscape has created dramatic lava tubes, arches, and underwater caves, while warm, crystal-clear waters support vibrant coral reefs teeming with marine life. Divers often encounter Hawaiian green sea turtles, schools of tropical reef fish, moray eels, and even playful spinner dolphins. For an unforgettable highlight, many operators offer the Big Island’s signature adventure - the manta ray night dive - where graceful mantas glide just inches away under the glow of underwater lights.
Whether you’re taking your first breaths underwater or have years of diving experience, there’s a trip designed for your skill level. Options include beginner-friendly shore dives, 2-tank boat trips to pristine offshore sites, twilight and night dives, and advanced charters to deeper reefs and pelagic zones. Top-rated dive shops provide quality rental gear, detailed safety briefings, and small-group experiences for personalized attention. Many tours also include underwater photography services, so you can take home lasting memories. With visibility often exceeding 60–100 feet, booking early ensures the best sites and conditions - and don’t forget to use reef-safe sunscreen to protect Hawaii’s fragile marine ecosystem.
