“Fun trip with a fun tour guide, Kap?, and group. Saw many places and many beaches. I wouldn’t waste my time on the Dole Train next time. Saw many plants, but too long with the return trip useless. We had to hurry to the train, and then buy Dole Whip. No time to look in shop or around grounds. Our snorkeling beach was too rocky to really enjoy the beach.”

I swam around with a deflatable life vest, diving at my own pleasure for approx 1.5 hours in total. the turtles were fascinating, alot larger than expected. would definitely recommend this tour group for the activity. I went early morning at 8am so it wasn't too hot, and the water was super clear and a good temperature! great experience if you love the beauty of nature”
