We really enjoyed our day trip on speed boat on a perfect day to koh tao (beautiful) Nice lunch and water was amazing to swim in. Kho Nang -yuan was absolutely beautiful. Snorkeling was ordinary compared to other countries we have been to, but still enjoyed the day. Staff were very helpful and friendly and would recommend a day trip away from Koh Samui to see the beautiful islands before they get spoiled. Only complaint was the unfriendly people on our trip but that cant be helped!
