If you walk far enough north along the concrete path on the east beach of Railay (About 10 mins from the main strip, past Last bar and keep on following the path) there is Tew Lay Bar, we just set about following this path after breakfast one day and came to find ourselves here. We stopped and had a great well made coffee, the best coffee in Railay we had found, and the bamboo deck looking out across the bay isn’t so bad either!
They also do cooking classes which a friend of mind has taken part in and the review came back great! You can check out their Facebook page, or stop buy for a coffee, snack or cooking class!!
