“Well organized, incredibly friendly guides. Best snorkel and sandbar spot. Super blue water. Actually got to swim with a sea turtle. Incredible Mountain Views. Staff went above and beyond to make sure that we saw and understood all the wild life. Lastly they gave us a dinner recommendation, which turned out to be our favorite meal of our entire trip. If you’re staying in Waikiki, it is worth the trip to the other side of the island, as opposed to all the trips that take you to turtle canyon right off Waikiki. This trip was 1000x better!”

★★★★★★★★★★5.0 · 206 reviews · 1 hour (approx.) · from $38Best value

Waikiki snorkeling with Lynne in shallow water, $38 with free photos and video in a small group for all levels.

“I always enjoy underwater adventures but I didn’t appreciate this experience so much. The group leader was fine but it bothered me that they provided people with reef shoes instead of find. The reef is in such bad condition that I would love to encourage this leader/business person to rethink their practices by not taking people out who need to step on the reef to feel safe or pick another spot. I would’ve loved to learn what we can do to help revitalize and repair the reef and go home understanding why the reef looks so bad. This experience felt very touristy and simplistic.”

“Fumio was absolutely amazing. Besides being super friendly she was great. It was the best experience ever and all we had to do was bring our suits and towels and show up. We were only with one other couple and one of them was not a great swimmer. Fumio basically tethered herself to the young woman to make sure their experience was awesome as well. The videos Fumio shared were great and she knew the best places to take us at Hanauma Bay. This experience is for sure more expensive than many others but the personal attention that was given to us and Fumio’s knowledge of Hanauma was more than…”
