Today is a challenge day, and along ways as its more than 100 km. Your guide will cut off some serious hills and enjoy the best scenery along undulating roads. To avoid many big hills, we will have a transfer to the top for moderate biking through jungle. Ride past villages of ethnic people, stop and find out where plenty of wild animals’ meat selling on roadside. Stop for lunch at Pak Mong. From the fork/T-junction of Pak Mong, the road to Nong Kiaw is the best. With moderate hilly back roads, past local markets, rice terrace paddy fields and scenery along River bank and limestone mountains allows you challenge some gentle hills on your biking  to the cave, then riding to Nong Khiaw brigde, enjoy sunset as the sun is being down behind the mountains
