Such a fantastic experience!!! My sister first went diving with Greg in 1997 and highly recommended him to us....20 years later my son Quinn( 9 years old)went for his first dive with Cassie, (Greg’s daughter) We came from Nebraska and this was his first experience in the ocean.... with fish, and he had an amazing time! My family and I came back to Kauai in July 2019 and this time my son went diving with Greg and yet again had an awesome experience where they saw an assortment of sea life including turtles, eels and even a reef shark! To say the least my son was hooked! In December 2019 I decided to take Quinn back to Kauai to get PADI certified with Watersports Adventurers(for his 12th birthday) Cassie was his instructor and was AMAZING! (she even sang Happy Birthday to him in Hawaiian!) We now live in San Diego so it would have been convenient to do the certification here, but because of the amazing and safe experiences we had with Greg and Cassie I wouldn’t have dreamed of going anywhere else! Plus I wouldn’t have trusted anyone else with my son. Cassie and Greg have given my son such an awesome opportunity and taught him to appreciate, respect and love the ocean and all of the creatures in it, especially on Kauai! I cannot say enough wonderful things about Cassie, Greg and Watersports Adventures. I definitely know we will be going back and I would encourage others to do so as well. 😊 Mahalo nui loa!!!!
Kristy KremanVery friendly. Had 2 great dives at tunnels beach. Excellent dive site from a limited access beach. Great small family operation. Accommodated our group of certified and non certified divers. Saw sharks, turtles octopus, Monk seals, caves, lava tubes and much more. Cassie was amazing. Thank you for showing us a great time.

My teen daughter, husband and I dove on Thanksgiving morning with Wayne on the south shore. Only my daughter and I had dove before but it was in a swimming pool 4 years ago! Haha! Wayne was amazing with training us, calming us down and then having us hang on to him as he took us down into a beautiful reef 40' down. The experience was life changing. We saw so much marine life it made both my family and I have a new appreciation for what lies in the sea. This is one thing in Kauai'i we will always come back and do! For someone looking for a great family experience, here would be the place to go! Wayne rocks! Mahalo!

What an amazing experience scuba diving at Tunnels on Kauai! Wayne was our instructor and he was top notch. We gave us a thorough introduction because we hadn't been diving in about 3 years. I was a bit nervous before getting in the water, but that longer introduction calmed me down. We dove with Wayne and one other guest from the Westin in Princeville and it was an awesome, personal experience. We loved exploring the caverns! Wayne showed us sharks, eels, turtles, sea slugs, and tons of fish. Thanks for everything, Wayne!

Beware Gregg's "free" intro to scuba class at the Cliffs at Princeton or any other resort. He will hard-sell his scuba services by trash-talking the other vendors on the island and does not give group discounts like the other vendors. When he saw us at the dive site with another company, he starting making snide comments about how he "wasted his time on us" and told us that he "doesn't need our business" and that he "is plenty busy. I don't give away my services for free." He was yelling at me to "shut your mouth" in front of his customers as he was entering the dive site!!!
A total unprofessional. Businesses like this cannot last.

We were very impressed on what we saw during our shore dive at Kaloa Landing. Wayne and Derek were very knowledgable and friendly, and pointed out turtles, eels and different types of fish. Granted there wasn't a big area to see (perhaps one tank instead of two tank dive would suffice), but there was quite a bit to see. Sure we didn't see whales or dolphins, but 'can't have high expectations from a shore dive. We got the premium service since we had two dive master/instructors for both of us :)
Downside was the price a bit high for a shore dive (about $130 per person for two tanks-we booked through the Cliffs) and there were no facilities in the area. They did have out-houses though.
I would recommend this if you want a quick dive without the boat ride and want to see quite a bit. Wayne and Derek were great and made the dives awesome!

Had a great Scuba adventure today with Watersports Adventures! I'm certified but haven't been in the ocean in 7 years. Wayne and Cassie were great guide giving me a refresher and giving my kids an intro to Scuba. Greg and Holly at the office were super helpful getting the dive setup.

This was the best private charter of the Napali Coast I've done so far. Gregg and Troy are experienced watermen who have spent their entire lives on the ocean and definitely emphasize safety above all else. We had the boat to ourselves - 7 of us not including the crew fit very comfortably- and it was not crammed with dozens of other tourists like other tours I've done. It's also not the kind of boat that will get you seasick. We left out of Hanalei in the morning, toured the coast, went to a secluded beach and took a very short hike to an epic waterfall, and then headed back by early afternoon - perfect way to spend a half day. Wonderful experience, thanks guys!

I went on a two-tank shore dive with Cassie July 22...our dive site was Koloa Landing. Both Cassie and the dive site were outstanding! Cassie's dive plan review was so... read more interesting...she covered some basic info in a way that was so informative. I've been diving since 1994...I think Cassie's dive plan was the best review I have ever experienced. There were only four divers in the group...I really appreciated the fact that they kept the group small and with similar experience. Cassie did such a great job of getting our attention and pointing out things of interest. We saw a frogfish, a lot of turtles, a zebra moray, a pepper moray, a snowflake moray, Hawaiian damselfish, an octopus, nudi eggs and a dragon moray. She kept the pace of both dives slow, relaxed and easy. I hope we return to Kauai some day and when we do, I will definitely be booking with Watersports Adventures! More

Had an amazing first time scuba diving with Watersports Adventures. Gregg is an amazing guide and a great instructor on Scuba safety and technique. He made a beginner like me... read more feel super safe and comfortable while scuba diving. Plus he has some hilarious jokes!

We had such a wonderful morning doing 2 shore dives with Cassie and Greg! They are so knowledgeable, patient, fun - as well as very conscientious of the environment... read more and safety! We had such a great experience in the water seeing all sorts of fish! Would highly recommend them to beginners as well as advanced divers. It was probably the highlight of our trip to Kauai!!

Watersports Adventures gave a class at the hotel we were staying at.
After an hour of instruction in the pool w/ Gregg, we decided to take the dive... read more and go in the ocean. With clear instructions and the feeling of being safe, the 3 of us (including a 10 year old child) were able to successfully dive off the shore of Koloa a few days later!!
If it weren’t for my hesitation, I think we could have gone to as deep as 40 feet! (I think we went down 10-15 feet). We saw many fish, turtles and even an octopus!!
I’d definitely recommend Cassie and Gregg at Watersports Adventures and will look them up again when we come back to Kauai and try diving again! I think we are hooked!
Side note- you are not allowed to fly until about 24 hours after diving (due to nitrogen in the blood from diving) so book your diving trip early on in your trip!

Greg Winston did a great job of reintroducing me to Scuba (I was certified in 1985 and logged over 150 dives around the world...but nothing since 2000). Friendly, knowledgeable,... read more and I love the 4 diver per dive master ratio they maintain. Highly recommended.
