Ko Olina Catamaran Sail and Snorkel with Lunch
angelafL1270KC, Sep 2026
This is a Must!!
Fabulous!!! Transportation went smoothly and the entire outing was amazing!! You should really just buy at least 2 bags of fish food pellets ($5 each) and then the Ko’Olina sailed out to an area to snorkel and once you released some of the pellets, you were ambushed by all the most colorful fish!! It was amazing!! Saw one turtle but the amount of colorful fish was great!! Excellent lunch and a Mai Tai and to round off the day and thanks to the great crew!! 5 stars!!

Tim and Emma were amazing! The winds were high today but they pushed through and gave us the confidence to snorkel in rougher conditions. We had an amazing time and it was very worth the money! Couldn't suggest this more! Already suggested this trip to my brother in-law!

An Amazing Local Kauaʻi Experience!
New York City
Kauai Eastside Waterfalls & Local Grinds-Small Group Tour

An Amazing Local Kauaʻi Experience!
I cannot say enough wonderful things about Shasta and this family owned tour company. This was truly a top notch experience from beginning to end.Shasta is a local, and that made our tour feel so much more special. She shared beautiful places around Kauaʻi that felt like the kinds of places only locals would know. We weren’t simply sightseeing. We felt like we were getting to experience the island through someone who genuinely loves it and knows it so well.One of our stops was the beautiful Wailua Falls, and if you have the opportunity while you’re there, I hope you also get to meet Makepa B, the Lauhala Man. He was such a special person to meet and talk with and added another wonderful memory to our day. I thoroughly recommend taking the time to visit with him. You can also purchase a beautiful handmade keepsake to bring home, which makes the experience even more special.Shasta also took us to a wonderful local spot where we enjoyed fresh sugar cane and smoothies made with incredibly fresh ingredients. These little local experiences were some of my favorite parts of the day because they made the tour feel so authentic. It felt like we were getting a glimpse of the real Kauaʻi rather than just visiting the usual tourist stops.Because this was a small group island waterfall tour, we received such wonderful personal attention. Shasta was lovely, knowledgeable, fun, and incredibly helpful. We all had such a great time with her.What impressed me even more was how much she genuinely cared about us. I needed to get to the airport on time after the tour, and Shasta went out of her way to make sure I got there, personally dropping me off. That kind of kindness and customer service is something you don’t forget.Between the waterfalls, the beautiful scenery, the local experiences, and Shasta’s personal attention, this was such a special way to experience Kauaʻi. I would 100% recommend this family owned company and Shasta to anyone visiting the island.We had so much fun, made some wonderful memories, and I would book this tour again without hesitation! 🌺🌴

Big Island: Hidden Craters Hike of Kona

unique hiking experience on the private land
Great hike up the ridge; I would rate it moderate, since it was long. The highlights were the cave or lava tube, the amazing view, and the variety of berries to try. The tour is very well organized; they provide backpacks, water, snacks, windbreakers, and gloves. Everything is good quality, well worth the money paid. The guide is very knowledgeable and points out all the interesting landscape and tells you the legends of the island.

Amazing trip to Lanai
Dan and Danny were awesome captains. They helped get our senior travelers on the boat with no issues and were very accommodating. Our kids (both under 13) had a great time swimming and snorkeling off the coast of Lanai. Marissa was an amazing host on the boat. The food was perfect for everyone to snack on. the views and trip were amazing from beginning to end.

Tour Guide Dave was amazing from start to finish. He engaged in conversation, got to know us, made jokes; not to mention his vast knowledge of the island, culture, and history. He taught us about Pele, how the craters were formed, and how to correctly pronounce commonly mispronounced Hawaiian words. The hike itself was amazing with the great views and wildlife. I would definitely do it again and recommend it to anyone I might know.

such a great excursion
Captain Dave and Marisa were excellent tour guides. Dave called and moved our booking out two more days because the water was not clear on the day of our booking. we had such great weather and the water was clear. Smooth ride with a little hawaii history. This was our first time using scooters to snorkel and if you can add this to your excursion, do it!!!! it just makes it easy. my teenagers loved them. Dave and Marisa provided drinks, sodas, waters and fruits and pastries. didn’t see hoards of fish. but saw a ton of different coral and porpoises. they were quite a few brightly colored fish. highly recommend. would definitely do a tour again with them!

Kauai with Coco
Coco was a delight and toured us to great sights in Kauai. She knew the local grinds vendors so we had delicious banana bread, macadamia and chocolate tastings, and shopping. The Poke lunch with Coco was fabulous. The waterfalls and views in Kauai were amazing! Coco spoke loud and clear which was welcome since from the back of the van it could be difficult to hear. Thank you for a memorable Kauai adventure!!

Excellent Day!
Coco is an amazing guide! We did the Waterfalls, Legends, and Geysers private tour. Our family of four had a wonderful day. Coco showed us some highlights we would never have even known about if we hadn't done this tour. She also shared with us some other "do not miss" tips. My son took careful notes of all of her recommendations and we tried them. She did not steer us wrong. She's very knowledgeable about the area, entertaining, and friendly. If you're on the fence about this tour, just do it!
