Lively snorkel experience

Great time snorkeling with this crew! We saw a lot of fish and many sea turtles. My daughter loved jumping off the side of the boat over and over! Drinks were great too!

It was a blast!

My husband and I had a wonderful time on the 2:30 Sunset Cruise. The guys sailing us out were super nice. It was beautiful on the water, and we even saw a turtle in the water! The Mai Tai drinks they had on board, were actually the best we had the entire trip. I would defiantly recommend this experience! P.S. you could get soaked...we did :-)

So much fun! One of the more affordable sunset cruises and 100% worth it. The workers on the boat were friendly and upbeat and did a great job of cultivating a fun vibe. Would do it again in a heartbeat.

Sunset Cruise

Best part of my trip! Kalani, Mina, Mitchell and Justin were great. Super nice and friendly. The views during sunset were incredible. I will definitely be booking this again when I come back to Waikiki. Thanks Manu Kai crew!

Great time!

This was a great experience. We went on the morning snorkel tour and had a fantastic time! The boat comes right to the beach at Waikiki. The people were fantastic!!! We saw 3 turtles and lots of fish at turtle canyon.

Diamond Head Tour

We did the Diamond Head Tour and had a great time. This is a 90 min tour with sails up. Captain and crew were great. Great views of Waikiki and Diamond Head from the boat. The Manu Kai is small enough that you really felt the waves and were really sailing. Crew were manning the sails but still had time to make sure you had mai tais. Overall a great time and highly recommend.

Sunset Cruise

Well worth the money. Great crew, drinks included. Plenty of room on the boat. Friendly atmosphere. Bring a camera or iPhone, maybe a sweatshirt for after sunset. Expect to have a great time for $40.00. Definitely would go again.

Great turtle experience

We chose Manu Kai for the mid morning turtle snorkel at Turtle Canyon and had a terrific time. We saw plenty of turtles and fish and enjoyed the professional but casual, laid back vibe of the crew. Jess in particular was outstanding (with a background in marine biology). Post our snorkel we headed towards Diamond Head for a great view of the beach and were lucky enough to see dolphins at play. A great morning trip.
