Leave Hanoi behind and travel by bus to Hoa Binh. When you arrive, you’ll jump on your bike and cycle to Cao Phong, through small ethnic Thai villages and paddy fields. Limestone peaks climb in the background and banks of green line the road, so you’ll take regular stops to admire the view across the valleys. When you arrive in Cao Phone, take a short bus ride, stopping for lunch at Man Duc. After you fuel up, the bus will take you to the Da River Reservoir. Cycle along the Da River, past the karst cliffs, beside green paddy fields and into the panorama of the Mai Chau valley. The town of Mai Chau is surrounded by green mountains and is famed for its breathtaking scenery and friendly hilltribe peoples. Tonight, you’ll enjoy local hospitality in a simple stilt-house homestay in the village of Poom Coong. Your amicable hosts will cook up a traditional meal, and there may even be a chance to sample some of the local rice wine that’s produced in the region.
