The weather disagreed a...

The weather disagreed a bit, but the crew made sure the experience was still a great one! Margaret and Lucy made sure to call out all the turtles in the water to give everyone a chance to see them. They also provided great recommendations for dinner. Captain Krash provided a safe and fun filled environment with great music. Will definitely book again next time we're in Oahu.

Oahu: Grand Tour Around Island with Snorkeling

Alisa_D, Sep 2026

“Oahu: Grand Tour Around Island with Snorkeling” is operated by Nui Tours.

An amazing experience from beginning to end! Everything was perfectly organized—communication, pickup, timing, and the entire tour. What made the day truly special was our guide, Aka. He didn’t just show us Oahu; he brought Hawaii to life. Through his knowledge, stories, and passion, he immersed us in Polynesian and Hawaiian history, culture, traditions, and art. We arrived as tourists, but left with a much deeper understanding and appreciation of Hawaii. Thank you, Aka, for making this experience so memorable. Highly recommended!

The coolest thing I have ever done

This was seriously like the 4th best day of my life - after my wedding and two kids being born. If I lived here, I would bankrupt myself doing this every day. I can’t swim and have never snorkeled before so I was absolutely terrified and didn’t think I would get in the water. Captain Caleb and our deckhand (I forgot her name, I’m so sorry) were amazing. They helped everyone to feel comfortable and educated about what we were doing. I never wanted to get out. I would absolutely recommend doing this!!

Susana_D, Sep 2026

Excellent experience, tracking pole recommended. Moderate to difficult, hard on knees

Pickup on time, friendly and knowledgeable guide. Safe driver. The climb was more strenuous than anticipated. Not a moderate hike. Tough on the knees. Recommend tracking poles. The unevenness of the terrain makes it moderate to difficult. It would have been easier if we had at least another half an hour to climb at a more reasonable pace considering how crowded the hike is and narrow paths.

Worth the Day Trip

Kevin was very chill and knowledgeable. His commentary seemed more organic rather than scripted. Loved how the company took care of the airline booking. No issues. Grab 100% Kona coffee from Joe’s. Not a lot of good food options at the Hilo airport at the end so make sure you buy extra food at the bakery in the morning. I regret not getting a loaf of sweet bread to go.

Kualoa Ranch Jurassic Adventure Tour

Bailey_l, Aug 2026

Breathtaking sceneries!!! Fun tour!

I had an amazing time on the Jurassic Adventure Tour at Kualoa Ranch! The scenery was incredible, and the tour was both fun and informative. Our guide, Matt, made the experience even better. He was funny, helpful, and genuinely friendly throughout the tour. I was traveling solo, so he also unfortunately ended up becoming my personal photographer—and he was a great sport about it! If you are a Jurassic Park fan or simply want to explore one of the most beautiful places in Hawaii, I highly recommend this tour (ask for Matt if possible). Thanks, Matt, for making the experience so memorable!

Oahu 5-in-1 Deluxe Cruise: Turtle Snorkeling & Ocean Activities

Amy_D, Jul 2026

Great trip!

The crew was great… they have a tough job! They are responsible for the safety of so many people and they take it seriously which they should as the conditions can make for a dangerous situation if one is not a strong swimmer. So listen to their warnings and obey directions and you will be fine. We got lucky and had like half of the people that the boat can hold. There was a swell coming in so we couldn’t see much but luckily, we saw two sea turtles, swimming along us as we were anchoring. It was just nice to be in that beautiful blue water and enjoy the ocean. They provided granola bars and some orange drink and water. I saw people with beer that they had brought on themselves. My husband and I did not use any of the inflatable stuff even though we had purchased the right to do so. I know that you can get a pink wristband which does not include the inflatables and pay a little less, but I’m not sure how to do that on their website. The boat is awesome and they get extra credit for playing a lot of great country songs! Thanks for a great time!

Amazing - best way to go to Hanama Bay

My wife and I love this trip out to Hanama Bay. We have been multiple times and taken our own car, taken a taxi, taken a 12 passenger bus, and none of these compared to the experience with Roberts luxury bus. Pick up. Was perfectly on time and we left right away. The lady who drove and narrated did an amazing job and was so interactive.

Excellent tour and even better guide!

Our original company cancelled last minute so this was a quick pick on a wing and a prayer. The bus was super comfortable and our driver, Mo, was absolutely outstanding. She was friendly, polite, funny, and crazy informative. She knew history, geography, legends, any answer to any question...and made us feel like Ohana. It was a pretty inclusive tour giving us a sample of all Oahu had to offer. Mahalo!
