Dive Rating

Moderate
to
Advanced

We rate every dive by the day, not just the site. On a calm morning this dive is moderate. When the swell is up it is advanced. Our captain and divemaster read conditions every morning, pick the site, and make the call before we leave the harbor.

Easy

Calm, protected water. No experience needed. Good for beginners and families.

Moderate

Some waves, current, or uneven footing. Comfortable swimmer with some ocean time.

Advanced

Rough water, surge, or depth. Strong swimmer with real experience in the activity.

Expert

Our most demanding conditions. Experienced guests only, on the best days.

Book at your level. Check the rating and the local weather before you book. Be honest about your experience.

Our Dive Spots

The captain and divemaster choose the site each morning. These are the reefs we run to from Hilo.

About the Dive

One tank from Mālama i ke Kai, Hilo’s only commercial dive boat. We run out past the breakwall to a reef site along the east side coast. There is no set site. The captain and divemaster pick it the morning of, based on swell and wind. The map above shows where we go.

You gear up on deck, get a site briefing, and back roll in. You climb out by ladder. No lava rock entry, no carrying gear over a shoreline. Expect coral ridges and volcanic terrain from 40 to 70 feet. Conditions out here move, so you need to be comfortable in open water.

It is a short trip. You are back at the harbor in about 2.5 hours, with snacks and drinks on the ride home.

Guided by Local Divemasters

You get a site briefing on deck before you gear up. Your divemaster leads the dive, sets the pace for the group and the conditions, and points out what you would swim right past. The captain stays with the boat and picks you up when you surface.

We dive with fin awareness and reef-safe sunscreen, and we expect the same from you. Read about our conservation work and help us mālama i ke kai, care for the ocean.

Flying & Elevation

Wait at least 12 hours after a single dive before flying or going to elevation, and 18 hours if you dive more than once that day or on multiple days. That includes driving Saddle Road to Kona, Mauna Kea, and Volcano. Plan your dive day around it.
