Manta ray night snorkel tours in Kona

Six evening snorkel trips leave from Keauhou Bay, Keauhou Harbor and Honokohau Harbor to the lit viewing areas where plankton gathers and the resident reef mantas come up to feed. The tours on this site are compared below by length, starting price, rating and the language the crew works in.

Updated 21 October 2026

In shortFor a quick, low-cost first look at the mantas, the 1.5-hour trip from Kona and the 1 h 20 min Keauhou Bay departure cover the essentials with the shortest time on the water. The 2.5-hour Big Island snorkel is the most reviewed option and includes a wetsuit top, flotation, water and snacks, while the small-group Manta Magic trip caps numbers at 12 passengers. Choose the 2 h 15 min catamaran for a sunset sail before the snorkel, or the 3.5-hour Honokohau Harbor trip if a head and a warm fresh-water shower on board matter to you.

How to choose the tour

Departure point is the first thing to settle, because it decides how long your evening runs. Five of the six trips leave from Keauhou Bay or Keauhou Harbor, a few minutes south of Kailua-Kona, and reach the lit viewing area off Kaukalaelae Point in three to five minutes of boat time. The sixth leaves from Honokohau Harbor and runs up the coast to the northern viewing area, which is why it is the longest night out at 3.5 hours.

If you sleep in Keauhou or Kailua-Kona

Staying in Keauhou puts you within a short drive of the pier on Kaleiopapa Street, so the shortest trips make sense: the 1.5-hour Kona snorkel with its three-minute transfer, or the 1 h 20 min Keauhou Bay departure, which runs slots from 6 p.m. to 10 p.m. and suits a late dinner either side. From a Kailua-Kona hotel, Honokohau Harbor is the closer marina, and the 3.5-hour trip from slip G-2 checks in at 4:15 PM HST, which turns the outing into the whole evening.

Language

All six tours on this site are run in English. The briefings, safety instructions and the live commentary on the mantas are delivered in English by the captain and the snorkel guides, so a working knowledge of the language helps you get the most out of the in-water part.

Budget and comfort

Starting prices on this page run from $95 to $155 per adult, and the gap mostly reflects group size, boat and what is included. The 1.5-hour trip from $125 and the 1 h 20 min trip from $95 are the leanest options; the 2.5-hour Big Island snorkel from $138 adds a wetsuit top, flotation, bottled water and light snacks, and it carries by far the most reviews. Spend more and you buy space or scenery: Manta Magic from $145 caps the boat at 12 passengers for one focused hour, while the catamaran sunset trip from $155 gives you a 50-foot deck, a sail along the coast at dusk and 2 h 15 min in total.
