We were given a choice of where to go and were told to visit Koh Racha Island - a lovely bay about 45 minutes from Cape Panwa - so we did. The island is home to an exclusive hotel - The Racha but we did not visit.
The journey on the Panwa Princess was fun and the boat crew were always there with a drink.
The bay at Koh Racha was certainly calm and the boat was almost immediately surrounded by fish. The local restaurant was great - there was even a sea hawk at the front - although I was later told that it's wings were clipped.
