Thailand's answer to a Mediterranean corniche: the Chaloem Burapha Chonlathit scenic road threads the quiet eastern seaboard between Chanthaburi and Trat, swinging over red-rock headlands and past casuarina-lined beaches with almost no traffic. The S-curves below Noen Nangphaya viewpoint are the most photographed stretch of coastal road in the country. Easy riding, big views, great seafood — an ideal rest-day ride or a relaxed link toward the Koh Chang ferries.
