Once in Pattaya, you cannot absolutely miss this tour, as this is one of the highlights of the Pattaya area: the Grand Coral Islands. All the water activities like jet skiing, banana boating, parasailing, and underwater sea walking are brilliant in their own way, and one needs to experience them. The tour was very well organized, as usual, by Klook.com. Early in the morning, they picked us up from the hotel, and from that moment until the end of the tour, it was thoroughly coordinated, including a good lunch. The guide was with us throughout, guiding us on how to Proceed step by step . This is highly recommended.
