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.

Our custom light boards use over 150,000 lumens of blue dive light, attracting more plankton and increasing your chances of manta sightings.*

2.00Three minutes out on an inflatable boat and three minutes back. Twenty minutes in the water to see the rays (a group of 17 people, but surrounded by other huge groups, so it doesn’t feel intimate). People shouting the whole time. Extremely overpriced for what it is. It’s basically the same as doing the activity with a larger, cheaper group.
Very fun activity!

3.00Research time for best opportunity to see mantas. Also check the amount of time in the water. There were other boats that arrived before ours and were still there when we left. This was a 30 minute experience so if you want more time to see more mantas, check the details. We have done this four times and we never paid extra for the wetsuits. There was an extra charge for the suits.
