The fourth day's ride is more challenging than the past three days. The type of local's living we see today is also more characteristic of the places you have been and seen. In the morning ride, you will cycle on a quiet country road through local factories making bricks and local markets and meet locals who rarely see Westerners at their homes. After lunch, to avoid getting hot at noontime, we will have a transfer to Ba Chuc killing field for a short visit. Then we continue cycling on natural hilly back roads through small villages and picturesque pagodas and stop at Tra Su Natural Reserve. A boat trip will take you through the forest with trekking around the area. After the boat ride, we continue to ride on the path to Sam Mountain, where we get on an A/C van for a short transfer to Chau Doc. If time permits, the ride will continue along the border to Chau Doc.
