Koh Kradan is located just south of Koh Lanta. It is located in a group of three similar islands, the other two being Koh Mook and Koh Hai.
It's best from the point of view of the weather to visit Koh Kradan is between 1st November and 1st May, when the island is not affected by the south-west monsoon. Between May 1st and November 1st the weather is not as stable, but the prices at the island's headline resort, the Seven Seas, are considerably lower, making a visit in the low season an attractive proposition from a financial perspective.
After this one last beach image, we'll take a look at some resorts.
