07/10/2011 Mark L. (Avg: 2.56 Review) - To update everyone, as of this writing there are two Manta Ray dive sites. The original one was off the Kona Surf Hotel, which is now a Sheraton Hotel. Manta rays congregated in this area at night to feed on the increased concentration of zooplankton attracted by bright lights that the hotel directed at the water. A second site was developed at the old airport when the lights at the Kona Surf Hotel went dark as it was being remodeled. Since the remodel, the Sheraton has turned the lights back on, and the manta rays have returned. Both sites are now used by dive tours. The old airport site is much less accessible as a shore dive, so we explored the one off the Sheraton Keauhou Bay, at 78-128 Ehukai St, Kailua-Kona, Hawaii 96740. GPS coordinates: N19.33.345 and W155.57.589
We visited the Sheraton during the day to gather information and survey the site and conditions. I strongly recommend that you do this if you are considering a night dive here. On the day we arrived the conditions were very good with minimal swell. Our plan was to try this as a snorkel adventure and then return another night if we felt that it warranted scuba gear. After sunset manta rays congregate in shallow water, 7 to 20 feet deep, off the Sheraton's 'Manta Ray Bar & Grill.' You'll see the big lights on the outside of the building. See attached aerial photo of the site. Dive tours will tie up to underwater markers about 200 ft offshore. We waited until just after sunset to see the dive tour boats pull up, loaded with $100-$150 paying passengers. Then we slipped into the water ourselves. The boat ride costs money, but it is otherwise a free ocean.
There are several choices for entry off the lava shoreline of Keauhou Bay; none are for beginners with full scuba diving gear. Snorkeling gear is much easier to manage and you will see everything just as well and as close. Really. The lava is not all that slippery, but it is hard and sharp. Wear your booties or flip-flops to your chosen entry point. The real consideration will be your exit, and this depends on your level of skill and the swell. Pre-plan it! Attached photos will give you an idea of what to expect. We chose to jump off a lava point in the area marked on the map and photo 1. This minimized the swim out and was fun as well. The drop was only about 6 ft and the water was very clear and deep at that spot. Obviously, don't jump if the water doesn't look deep enough, and regardless, don't jump head first. The jump was easier and probably less dangerous than trying to negotiate our way out from some of the shallow entries, like photo 2.
The lava shoreline area is dark so you will need to bring your dive lights to see your footing. You will also want your underwater lights to attract the manta rays closer during your dive. The brighter your light, the better, although you can mooch off the light that the tours use. Remember, the visibility is usually awesome so you can stay back a respectable distance from the tour group and still see everything! You will definitely want your light as you exit the water to check that spiny urchins aren't in your path. We brought a $3 inflatable mattress to cling on and keep the two of us together. We also wore thin wetsuits. A sign on the shoreline warned of the possibility of marine stingers, urchins, and eels. There were a few urchins, but we did not see or feel any stingers or eels. I think they threw in the part about the eels to scare you onto the dive boats! Stingers may be seasonal, so a wetsuit is not a bad idea. The fee-paying snorkelers from the boats all had wetsuits even though the water was about 77 degrees Fahrenheit.
There were only a few scuba divers on this night. They each had super bright lights, so they may have been tour employees. The old airport site is deeper and probably better suited for scuba diving.
We chose to exit at the spot shown on the map and photo 3, just past a little shack that sits on the lava shoreline. We found a few old metal fasteners that are embedded into the lava and they made good handholds for climbing out. Be aware that the surge is lighter as you get farther into the bay, making for an easier exit. You could go all the way to the boat launch ramp and walk out if you felt that the swim was safer and easier than the climb out onto the lava.
The manta ray snorkel dive was very cool. Do not miss it. Go on the tour and pay the money if you are a beginner. They do a safe job with lifeguards, floaties and all. We did not think we missed anything by not using our scuba gear at this site. It is very shallow and very clear. Snorkelers just float at the surface and do NOT dive down during the show that the manta rays put on. They will come plenty close enough to you! One 10 footer bumped us as it was swooping in on the zooplankton in front of our lights. They are harmless unless you are krill, but trying to touch them is in poor form.

02/03/2011 Kim Hutchinson (Avg: 3.49 Review) - This is a great spot for Manta's however I much prefer a boat dive for the night dive. Road is rugged and it's tough getting out at night from shore. I will be there again in 2011 and will do a boat for this dive.

02/04/2008 Steve Porter (Avg: 3.30 Review) - The "NEW" location of the Manta dive is 7 miles north of the Kona Airport at Kekaka Kai state park. You're going to need a rugged vehicle to get out there (JEEP). The road isn't clearly marked, so look for the road on the left that has about 20ft of pavement turning to a dirt road over lava rock. There are no facilities whatsoever, and going down the lava rock to the water is a bit tricky. Bottom conditions are fairly good, and if you want to be the only shore diver, this is it. If you go at night for the mantas, expect crowds but not in the parking area. You can dive here year round, too. Since it's snorkeled, I gave it a good score as well. I've seen it free dove during the day, and people spearing say it's good, because of its tough location.

06/27/2003 Bill Stohler (Avg: 2.19 Review) - The former site of the Manta Ray Night dive is no longer being used due to the migration of mantas from the site (presumably due to too many divers). The new locations vary, dependent on the operators. Sightings are not guaranteed, although if you are lucky, you'll have a great experience. Last month I went to Kona and dove with two mantas in the daytime, just off Old Airport. Awesome creatures, and magical at night, when they feed on the plankton and krill attracted by the divers' lights! Ask the boat operator if the mantas have been sighted regularly in recent days, and good luck!

06/24/2003 Chuck Knauf (Avg: 3.00 Review) - I noticed that you have the Manta Ray Night Dive on the BI of Hawaii listed as a future dive site. I think it is a GREAT idea! I have made the dive numerous times. However, shore diving is not the norm for this dive any more. Most of the night dives for viewing and interacting with the mantas are boat dives at Garden Eel Cove (off the Kailua-Kona Airport) about 7 miles N. of Kailua-Kona. Shore access isn't available that I know of - it would be a LONG swim. The dive operators set up lights on the bottom to attract the sea cooties that the mantas feed on and divers add more light with dive lights. This is a 2 tank dive. First is a twilight dive on the reef and down to the Garden Eels at about 70 feet. Second is the manta dive after dark where we set-up at about 40-45 ft down. The last time I did this dive, I must have REALLY upset a yellow margin moray eel as we sat on the bottom. I must have been in his space and he kept attacking me. Had to fend him off numerous times with my dive light!! After about a half hour with the mantas, we pick up and tour the reef viewing the eels and other sea life out hunting. It has been discovered through research that the mantas come from MILES away just to feed here with the diver's help in attracting their food. DO list this dive! I have seen from 2 to 4 boats out on this dive. It is not crowded. Next trip will unfortunately not be until Nov '03. I suggest Jack' Dive Locker as a dive operator for this outing. Keller Laros, who is usually a dive leader on this dive with Jack's is also an expert in manta ray identification and is also heavily involved in manta ray research.
