About the Dive

Join us aboard the Hilo Horizons for a one-tank dive along Hawai‘i Island’s vibrant east coast! This quick but unforgettable trip is perfect for certified divers looking to experience Hilo’s coral reefs, volcanic topography, and marine life without committing to a full-day charter.

After boarding Hilo’s only commercial dive boat, you will head beyond the break wall to explore one of our favorite reef sites such as Horizons or Leleiwi Reef. Enjoy a calm, guided dive through coral ridges and lava rock formations teeming with tropical fish and sea turtles before relaxing with snacks and beverages on board.

What You’ll See

  • Vibrant coral gardens and volcanic reef structures shaped by ancient lava flows
  • Schools of tropical reef fish, from yellow tangs to Moorish idols and butterflyfish
  • Encounters with Hawaiian green sea turtles (honu) gliding across the reef
  • Coastal views of Hilo Bay and Mauna Kea rising in the background

Guided by Experts

Begin with a clear safety briefing and site overview, then enjoy a relaxed guided dive led by our experienced local divemasters. Your guide will set a comfortable pace, help with buoyancy and navigation, and point out camouflaged life such as octopus, eels, and cleaner stations. Small groups keep the experience personal and safe, and our captain and crew monitor conditions to choose the best site for the day.

At Hilo Ocean Adventures, we believe exploring Hawai‘i’s reefs comes with a responsibility to protect them. Our team practices and teaches eco-friendly dive habits, from proper fin awareness to reef-safe sunscreen use. Learn more about our ongoing conservation efforts and how you can help mālama kai — care for the ocean — during your dive.
