Aloha Ready4Lauch!
That is great you get to dive here on Kauai! Kauai is a very unique place to dive loaded with endless marine life! As I own/dive for "Explore Kauai Scuba", there are plenty of top notch dive operations here. "Koloa Landing" is an epic shore dive location on the south side that is close to all of the resorts, so very easy/quick to get to if you're staying on the south side. Koloa Landing is a great spot for such critters as frog fish, various scorpion fish, plenty eels including the dragon moray, sea turtles, the list goes on and on!!! I can't talk up Koloa Landing enough! Plenty of people visit and are ready to dive it again and again. This is why almost every dive shop offers shore dives here. It's a great bang for your buck and with depth range on average of 25-45 feet, you'll get longer bottom times. If boat is what you're looking for we offer boat dives out of the west side of the island, diving sites less dove. Some of these sites offer some less seen critters like pipe fish, endemic lion fish, ghost shrimp, and a java moray to name a few.
Feel free to message me with any and all questions. If you go with another shop, feel free to ask me for divemaster recommendations, a seasoned DM goes along way in showing you our marine life in detail. Also, any other recommendations for while you're on island, hikes, restaurants, beaches, etc.
