Reviews: Hilo: Wailoa River to King Kamehameha Guided Kayaking Tour
Guest User2026-10-09
I had never kayaked before, but it wasn't difficult, and it was great to enjoy the river and the view in a cool, quiet environment. It was also really nice that they provided both pickup and drop-off services. Precious lived up to its name and gave me a precious experience.

Reviews: Kona Snorkel Tour: Captain Cook Reef Snorkel, Dolphin & Sea Caves
Guest User2024-07-03
This was a fantastic tour. It was a Small group, only myself and my son and then a couple. Our captain Jack (I hope Ingot that right haha I was in island mode) was very funny and knowledgeable about the legends and history of Captain Cooke and the people of the Island at that time. I love history so I really dug the stories. After swimming for more than an hour over the reef, which was truly magical, he served us fresh local pineapple and other snacks, which was perfect because swimming really is a workout! we had extra time so he took us to some extra locations that were really beautiful and told us the stories and legends. I love photography and was able to get incredible shots. Overall it was just super relaxed and my son had such a good time as did I. I would definitely recommend this tour!

Wonderful snorkeling! Had the best time with the kids snorkeling in the bay, going off the slide and even treated to a yummy lunch and snacks. Would do it again!
