Hieu Waterfall (Thác Hiêu)

The falls are just off National Road 15C on the east side of Pù Luông. From Hanoi (180 km, about 4 hours) follow the Ho Chi Minh Road southwest to Cẩm Thủy and Cành Nàng, then take 15C about 10 km towards Pù Luông. The other common route goes through Mai Châu in Hòa Bình. A private car from Hanoi costs about USD 60–70; shared tourist minivans cost USD 12–20 per person.

Without a car, take a bus or train from Hanoi to Thanh Hóa city (or fly to Thọ Xuân airport) and continue by taxi. Leave the car or motorbike at the village and walk up beside the falls. The path climbs over wet rock and crosses the stream in places, so expect to get your feet wet.

Best time: The falls carry the most water from May to September, and June is usually the peak, when the terraces around the village are also green. In September and October the rice turns gold and the water is still high. From December to April the flow drops and the upper pools get shallow, but the trail is drier and easier.

What to do: Swim in the bottom pool, then climb the rocks and wade upstream to the top of the falls, where you can see the stream split in two below you. Walk back through Bản Hiêu, which sits above the falls among rice terraces.

Food: Try Cổ Lũng duck, a short-legged local breed raised in the fields and streams, often cooked with bamboo shoots. Homestays also serve grilled pork, bitter bamboo shoots and cơm lam (sticky rice cooked in bamboo tubes).

Tips: Wear sandals or shoes with grip; the rock is slippery. Carry a dry bag for your phone. A small entry fee is collected in the village, so bring small notes. In summer, weekends fill up with groups from Hanoi; go on a weekday or early in the morning.

Nearby: Bamboo water wheels at Làng Tôm, bamboo rafting on the Chàm River, Hang Dơi (Bat Cave), Lũng Vân plateau and the Pù Luông loop.
