John and Jeanette were excellent, hospitable guides that made sure we had a positive and safe experience. The snorkeling adventure to Captain Cook monument/Kealakekua Bay was well organized and so very pleasant. The boat ride was so refreshing and the snorkeling was beautiful. They taught us about the area’s history and wildlife, and pointed out all types of fun creatures to observe, including humpback whales, sea turtles, octopuses ,eels and many types of tropical fish. Drinks and snacks are provided on the way back as well. They had all the necessary equipment and helped us make sure it functioned well. I highly recommend this tour,! I’ve done it several times on repeat trips back to the Big Island . If you combine it with their amazing night manta ray tour, you get a nice discount.
