Do this! Don't think too much, just book this, it will be worth it. Doing this with a kayak was great and the tour guide was great! It was only 4 people including 2 of us on the tour.

This tour was amazing!

AMAZING!!!! DO IT!!! HIGHLIGHT OF OUR TRIP!!!
The mantas were SO BIG and graceful and strange. You'll absolutely love this experience.
You will meet the guides at the kayak shop and then drive your own car to the Sheraton Resort.
The guides transport the kayaks.
You can use your own snorkel gear if you have it.
Do some research about the mantas before you snorkel, as our guides didn't have any facts for us whatsoever. The guides were friendly and did a good job getting us set up though!
Leave all of your clothes/belongings in your car, as they'll get soaked if you bring them, and you don't need anything.
Go to the Sheraton before or after, as they have a beautiful restaurant and bar that overlooks the manta snorkel area and they have a really cool Manta Learning Center where you can learn about the animals.
SUCH AN AMAZING EXPERIENCE!!! Worth every penny!!!!!!

Aloha Kayak is REALLY BAD at communicating details of this trip. Phone calls and text were ignored. I finally got through once via phone and got someone that sounded like they only had an elementary school education. I was told to meet at the Bay at sunset with few other details.

No one showed up at the Bay that night at the arranged time, so I called Aloha Kayak and no response. 20 minutes late, the independent contractor for Aloha Kaya showed up with his girlfriend and said we should have met him at their office. He had no equipment for us, so we had to use all our own snorkeling gear and our kayak paddles. The rest of the kayaking and snorkeling part was good, but I did see another trip vendor at the Manta Ray site that looked well organized. After the Manta Ray activity, we had to go back to their office and fill out tediously long information and waiver forms, which pushed our night really late considering I had to drive two hours to get back to our hotel on the other side of the Big Island. Meanwhile, the independant contractor complained of working too many hours, but not making enough money with Aloha Kayak.

Previous to this in the afternoon, I called Aloha Kayak to rent a couple of kayaks so that my son and I could travel along the coast of sea caves. Once again, no answer via phone or text messages. We found and spent our dollars with another vendor.

Of all the vendors I had to use during my 10-day stay in the Islands, Aloha Kayak was the worst. I would HIGHLY recommend going with another vendor.

Quite an experience! It was a little scary kayaking out in the night but our guide was really helpful. Unfortunately no mantas showed up but some wild dolphins were around so that was nice. We will probably try again when we revisit Hawaii.

It was a disappointment as they did not have but one light to attract mantas and we had to keep going over by the boats with stronger lights see a manta and then we got chased away by their group leader.

The people who did run it were kind and helpful but this is a rag tag outfit.

What a wonderful experience seeing so many Manta Rays. What I liked about the tour company is they let you swim free. I would not of enjoyed being on a board or tied together. I did find it a bit uncomfortable not having a seat on the kayak. It was a little hard on the back kayaking just sitting on the plastic. I did find it well organized and had three people from the tour company with us. Had lots of Manta Rays and was glad I also had brought my own light. Loved the somersaults the Manta's did right under us. Recommended them to several others visitors on the Island that were staying at the same condo establishment I was at.

one word AWSOME!

I had a BLAST, and I didn't even see any Manta Rays! The whole kayaking and snorkeling aspects of this trip were enough for me!

LOVED EVERY MINUTE!
this tour was definitely an adrenalin rush but an amazing experience. one with many memories and stories to tell.
