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.

Unmatched Light Power

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

(*Mantas are wild animals—sightings are common but not guaranteed.)

Statistically Better Later Tours

Later tours often have fewer boats and more manta activity, enhancing your experience.

The powerful 150,000+ lumen dive lights attract plankton, which in turn draw in majestic manta rays that glide and feed just inches below you. It’s a breathtaking, up-close experience guided by our professional team, including a licensed captain, swim guide, and certified lifeguard. Water time is approximately 20 to 40 minutes depending on various situations ocean conditions, etc. *Statistically the later at night you go the more manta rays and the more time we have the manta rays increases significantly!

All the staff were friendly and and fun and did their jobs well. I learnt a lot about the manta rays and the strange story of their regular visits to the bay. The water was pleasantly warm - the manta rays were incredible and came up very close by choice. That point is also very important - the activity seems quite ethical, the rays are left alone to do their stuff and they're happy to come close doing something they would do anyway (eating large amounts of plankton). A win win arguably. Highly recommended - if you're a less comfortable swimmer it may be a bit scarier although the team were very supportive.
