Shorter Boat Ride

Get to the action faster with a quick 3-minute ride to the manta site—no long 30-minute boat ride like other operators.

Incredibly beautiful and unique experience. Helps to be comfortable swimming, treading water, and knowing how to snorkel. Warning: we all got a little seasick, and one of us barfed. They do sell anti-nausea meds at checkin. They offer wetsuit top rentals for $15, which you should get if you don’t have your own. Snorkel masks provided.
Fabulous experience! Crew and equipment were all top notch and couldn’t have asked for a better time. Thanks!

Definitely an amazing experience to able to get that close to the manta rays. The butterflies of the sea! Rory was a great guide in the water, helpful, patient, calm and collected. We felt safe with him being in the water with us. Checking in went smoothly but you’d have to drive to the harbor and parking is limited. There’s no shuttle. At the harbor, a lot of confusion as this guy with a beard conducting head counts speaking very softly while eating his poke bowl. Almost showing no interest in his job. Getting on the boat was a bit challenging due the current. Bearded guy lost his cool at girlfriend as she was trying to get up on the boat.
Great excursion

Wow! What a great experience. Knowledgeable guides. We felt very comfortable and had a blast! However, there were some younger children who didn’t come prepared- no wetsuits, wetsuit not on and out on boat, their own broken mask and they were miserable. This slowed us down from being pulled to feeding spot. But still, don’t miss this- great experience!
