Travelling in coastal Thailand during the rainy season is risky: it might bucket down for days, cities can flood, many businesses close shop, and if the sea whips up boat journeys can be dangerous. During the drier months (typically November-April) the Anantara Si Kao offers day trips to its private Beach Club on beautiful Koh Kradan. It rained every day we were at the Anantara, but it didn’t dampen our enjoyment of the hotel and its stunning location. Between the Kids’ Club and hotel-based activities like fish-feeding, our boys kept busy. And whenever the sun showed its face, we all rushed to the pool.
