Named Makako Bay by Hawaiians, Garden eel cove is the dive site name used locally by dive companies due to the garden eels living in the sand at 80 feet. As the sun dips below the horizon Makako bay turns into an underwater show of sorts with divers and snorkelers waiting in anticipation of the nightly manta ray show.

The manta ray night dive is one of the world’s most popular and unique dives with massive manta rays putting on an underwater show unlike any other.

What is Manta Ray Heaven / Garden Eel Cove?

Manta Ray Heaven / Garden Eel Cove is one of 3 manta ray night dive sights in Kona, on the Big Island of Hawaii. It is the most popular and best manta ray viewing site for scuba diving.

The reefs are often blanketed by squirrelfish and schools of goatfish are a common sighting. Of course we mustn’t forget about it’s namesake, the garden eels living in the sand poke out from their holes only to withdraw slowly as divers approach.

Manta Ray Sites on The Big island


Manta Heaven

The middle manta dive site and one of the best for scuba diving, Manta Heaven is where Kona Honu Divers goes nightly to do the manta ray night dive. We’ve chosen this site as our go-to because our values of safety and stewardship mean we’ve committed to the safest and environmentally friendly manta ray dive site on the island.

Manta Ray Heaven / Garden Eel cove is easily the best manta ray dive site because Keahole point blocks the southern swell that is typical in the summer. It also has plenty of moorings so most boats can tie up. It is also the best topographically with a ‘campfire’ that companies have set up so divers can gather around and view the mantas together. This means everyone gets a good show versus Manta Village where the rays are fewer and can be more fragmented. This means if you’re not in place and paying attention when a manta comes around you might miss it!

Kona Honu Divers has been committed only going to this site since 2018. Since then a few other operators has committed to only visiting this site seeing the benefit to the safety and environment that it offers. Sometimes we’re the only boat out there and we get a spectacular show all to ourselves!

It is located just offshore from the Keahole (Kona) Airport runway. The western most point on the island (Keahole point) is just to the south.

Manta Village in Keahou

The other Kona manta viewing site is located in Keahou off of Kaukalaelae Point just offshore from the Keahou Outrigger Hotel. This was the first manta viewing site established in the 70’s when bright floodlights from the hotel attracted plankton and the mantas took notice flocking to the area. Since then is has exploded in popularity causing congestion and angst with the local fishermen onshore due to the limited parking and small launch ramp. The site itself only has a few moorings and if the mantas don’t show up in Manta Heaven for a night or two all of the companies head to this site. This means there can be up to 40-50 boats in one spot running their motors while snorkelers are swimming around! It can get a bit chaotic.

Manta Village can get pretty busy with up to 40+ boats in the area all at once!

If you are considering visiting this site you might prefer the moonlight manta which is a later tour that goes out after many of the other operations have gone home. This is best during the busier times of year when school is out.

Manta Point in Kohala

This newer, less established site was set up as a shore snorkel from the Mauna Kea beach hotel in Kohala. It’s best accessible to people staying far north of Kona and is great for seasick prone individuals as the experience is entirely guided from shore.
