To get to Tranh Stream from Duong Dong, call a taxi, or rent a motorbike from your hotel, and head east on 30 Thang Tu Street. This is one of the island’s main roads — most locals refer to it as a highway — and it is paved the majority of the way to the stream. Stay on the road for roughly 5km until you reach what looks like an entrance to Jurassic Park on the northern side. It is a large, ivy covered gate, which probably used to say the name of the stream but now has its words obscured by vines.
Go through the gate, pass the gardens filled with sculptures and live cows, and head back to the small carport filled with motorbikes. Pay the man at the desk and up the path you go.
The stone path is well maintained and follows alongside the stream. There are several stops along the way on the trail. First, immediately upon your start, are some food and souvenir stands. Here you can grab a quick snack of corn on the cob, potatoes or deep fried bananas for your trip. Many Vietnamese families pack their own meal and eat it along the way, so be prepared to dodge the occasional family picnic. About half way up the path, a 15-minute walk, there is a 7m-high fall that is a little hard to see from the trail. But there is a small path down an embankment that provides a good view.
The final stop on the trail is a large waterfall, and the pool it spills into, where the adventurous can take a quick dip and go under the falls. The water is still pretty warm here and, if you stay toward the path side of the waterfall, fairly gentle.
