When travelers think of Ninh Binh, they often imagine limestone mountains, tranquil rivers, and slow boat journeys winding through lush valleys.
Among these natural treasures, Bird Valley (Thung Nham) and Dundj Valley stand out as two contrasting experiences — both beautiful, both peaceful, yet offering very different ways to connect with nature.
Located in the heart of Ninh Hai commune, just minutes away from Tam Coc and Bich Dong, Bird Valley (Thung Nham Bird Park) has long been one of the most well-known eco-tourism destinations in Ninh Binh.
Visitors come here to glide through calm waters by boat, pass under shaded grottos, and finally reach the bird sanctuary — home to more than 40 species and thousands of nesting birds.
At dusk, the valley becomes alive: flocks of storks, herons, and egrets return to their nests in a mesmerizing dance above the treetops.
Developed as a large-scale eco-tourism site, Bird Valley offers convenient services — electric shuttles, restaurants, souvenir shops, and well-built walkways — making it ideal for families and group travelers seeking an easy and scenic day trip.
Yet behind its comfort lies a vibrant natural chorus — a reminder of how rich Ninh Binh’s ecosystems truly are.
Inside Whisper Cave — where silence speaks louder than words.
Surrounded by mountains, Dundj Valley is where peace and nature embrace each other.
A hidden valley of joy – where every visitor becomes part of nature’s story.
If you’re searching for hidden places to visit in Vietnam or wondering about unique things to do in Ninh Binh beyond Tam Coc and Trang An, then Dundj Valley is a destination you shouldn’t miss.
Nestled deep within the Thung Nang region of Ninh Binh, Dundj Valley offers a rare escape — a place where nature still breathes freely, untouched by mass tourism.
Here, there are no concrete resorts, no noisy crowds, no artificial lights — only the whispers of the forest, the flow of clear streams, and the echo of wind through limestone cliffs.
Accessible via a short boat trip and a peaceful walking trail, Dundj Valley invites travelers to slow down and reconnect with the natural rhythm of life.
Inside the valley lies Dundj Cave, the largest natural water cave in Thung Nang, still in its pure state. Unlike other caves in Vietnam that have been heavily modified, Dundj Cave remains wild, authentic, and awe-inspiring — a living monument of untouched beauty.
Surrounded by majestic limestone mountains and ancient forest, Dundj Valley is more than just a scenic landscape. During wartime, this valley served as a historical refuge for local villagers — a place of survival and resilience. For centuries, generations of farmers and hunters have lived in harmony with the land, cultivating rice, gathering wood, and protecting the forest.
Today, Dundj Valley is opening quietly to the world — not for mass tourism, but for eco-conscious travelers seeking authentic, sustainable experiences in Ninh Binh.
Visitors can explore the cave by boat, walk through bamboo forests, meet local farmers, and experience Vietnamese rural life in its purest form.
If you’re looking for a slow travel destination in Vietnam — peaceful, natural, and full of soul — Dundj Valley is where the real spirit of Ninh Binh still lives.
Bird Valley and Dundj Valley are not rivals — they are two chapters of the same story:
the story of how Ninh Binh balances development and preservation, comfort and authenticity, accessibility and wilderness.
You can visit Bird Valley to admire the rhythm of thousands of wings at sunset —
then drift to Dundj Valley to listen to the quiet pulse of the earth itself.
In one, nature greets you loudly.
In the other, it whispers.
