Be prepared to climb a few steep steps. We got a little winded, but with a small rest, it was well worth it. The Zipline was a wonderful experience. I would definitely go again!

The absolute must do excursion in Oahu!

Our guide was amazing and the tour was emotional and breathtaking all at the same time. We visited on the 81st anniversary of the Japanese surrender on the deck of the USS Missouri. It was surreal to say the least.

Wonderful 3 part tour--Kayaking, Snorkeling, and Lunch on the Beach.

My kids and grandkids took this tour and absolutely loved it and would do it again. They were thrilled with the helpful guide and thoroughly enjoyed the Kayaking experience.Their favorite part was the snorkeling and seeing so many fish. Lunch on the beach was also a wonderful, relaxing treat for them. Thanks so much!! Outstanding tour!

Hilo Shore Excursion: Volcanoes National Park & Black Sand Beach

E3125UIellend, Sep 2026

No better way to see Hilo!

This was the perfect way to experience Hilo! We were picked up right at the port. The van took us to 7 different sites around the area, among them the black sand beaches, Rainbow Falls, Mauna Loa macadamia nut farm and our favorite, Volcanoes National Park. We were so fortunate! Along the route, we found out that Kilauea was erupting and we would be able to view it. Maggie, our guide, adjusted the route just a little bit, so we got great views of the volcano from three different locations. Maggie was such an enthusiastic, intelligent and informative tour guide. Everyone just loved her! Take this tour! There is no better way to see Hilo!

BEST SNORKEL 🤿 ON THE BIG ISLAND

BEST SNORKEL ON THE BIG ISLAND! Captain Skyler took my lady and I on the best snorkel trip we have ever had. His knowledge of the island, its history, and best spots to go was top tier. My only regret is that we did not book the manta rays with him and sea quest. Highly recommend sea quest and ask for captain skyler as he made an already good trip, the greatest.

What a fantastic day with awesome memories

Fantastic day on the water The three crew members were outstanding, so happy and helpful. The food were amazing, so tender and tasteful. Saw dolphins, snorkeling with reef fish and saw a sea turtle. We both enjoyed our time onboard so much and would highly recommend it. And went home with a great photo package. Will be doing it again next time in Hawaii

Hanalei Bay Morning Kayak and Snorkel Tour

mburckin, Aug 2026

Kayak Hanalei trip was super cool

Great tour! Our guide, Kolo is a Hanalei native who helped us learn about the area, the wildlife, share some great stories and play some music!The kayak is gentle, even when out in the bay it was pretty chill. The tide was low, so the snorkeling had to be careful around the coral, but we saw lots of cool fish, an octopus as well as a couple of turtles.Great experience overall!

Wailua River & Waterfalls Kayak Tour: Expert-Guided Adventure

Kayla, Aug 2026

A Magical Way To Spend Your Morning or Day

Kayaking up the Wailua River was a magical experience. The river is so serene, and filled with beautiful hibiscus flowers. It’s like a scene from a dream. The hike to the waterfall is a bit intense (mud, slippery rocks, fallen trees) but with the right footwear (reef shoes are ideal) and some patience it is a very rewarding hike. The waterfall is beautiful! We jumped in and swam under the fall, very refreshing. The lunch was delicious, especially after all the activities. The sandwiches and fresh pineapple really hit the spot. Our guide, Thomas, was exceptionally friendly and knowledgeable, sharing with us secrets of the forest. I would suggest going with the earlier morning tours, as it begins to get very hot in the afternoon. An overall beautiful time, highly recommend!

Must Do Snorkeling Adventure

We had an A+++ experience on this excursion! There was a small miscommunication with my booking, but Barbie was incredibly accommodating and made everything right. She truly has a heart of gold. It's obvious that she's passionate about giving back to her community, especially by making snorkeling accessible for those with disabilities. Her kindness and dedication are just as impressive as the tour itself.Barbie also sends a text the night before with clear directions on where to meet and exactly what to expect.The tour begins with an amazing presentation. I don't want to give away any details because I don't want to spoil it, but it's informative, engaging, and really sets the tone for the experience. If you've ever been hesitant about snorkeling or are concerned about safety, make this your very first snorkeling adventure. Safety was clearly the top priority from start to finish.I've been on more than 50 snorkeling excursions, and this was the first time my family was given magnetic shark deterrent ankle bands. That extra attention to safety really stood out and gave us even more confidence in the water.Viktor was our guide, and we had an absolute blast with him! He made sure everyone felt safe while showing us every square inch of one of the most beautiful bays in Maui. Along the way, he pointed out pufferfish, eels, turtles, and so much other amazing marine life that we would have completely missed on our own. He was knowledgeable, fun, and made the experience unforgettable.My kids especially loved using the sea scooters. After Viktor showed them a few tricks, they were doing somersaults underwater! My son even pulled off a double somersault with the sea scooter!This excursion was a 10/10 in every way. Between Barbie's genuine compassion and commitment to her guests and community, and Viktor's incredible guidance and enthusiasm, this was easily one of the best excursions we've ever done. I can't recommend it enough. Don't leave Maui without experiencing it, you won't regret it!
