Double Decker Root Bridge Trek, Nongriat

Difficulty: Moderate
Trail Duration: 1–2 Days
Best Time: October to April

Perhaps the most famous of all eco-treks in Northeast India, the Double Decker Root Bridge in Nongriat, Meghalaya, is a living marvel of natural engineering. Here, locals of the Khasi tribe have guided the roots of ancient rubber fig trees across rivers for centuries, weaving them into sturdy natural bridges. The most iconic of them all, the Double Decker Root Bridge, is a two-tier structure suspended over a gushing stream, drawing trekkers and photographers from across the globe.

Trail Highlights:
The trek begins from Tyrna village, requiring a descent of around 3,500 stone steps through dense tropical forest. Along the way, travellers encounter hanging bridges made of steel ropes, turquoise pools, and smaller root bridges that hint at the ingenuity of Khasi traditions. The natural soundscape of waterfalls, cicadas, and rustling leaves adds to the feeling of being immersed in a living rainforest.

Eco Value:
This trek is eco-conscious at its core. The bridges are functional examples of bioengineering, built entirely by hand without machinery, concrete, or chemicals. They represent sustainable architecture at its finest and are maintained by generations of villagers. Staying in homestays in Nongriat also ensures your contribution goes directly to the local community.

What to Expect:
Bathing in the crystal-clear pools of the Umshiang River, walking under thick forest canopies, and crossing suspension bridges that sway over roaring streams all make this trail unforgettable. A visit here is more than just trekking, it is about witnessing how humans and nature co-create.

Eco-Tip: Carry only essentials to reduce load on the steps, avoid single-use plastics, and always use the biodegradable waste bins provided by locals.

Stretching between Mawphlang and Lad Mawphlang, the route winds through rolling hills, sacred groves, streams, and small Khasi villages.

The trek begins from Ziro, home to the Apatani tribe, and continues into dense sub-tropical and temperate forests. The sanctuary is a haven for orchids, ferns, and bamboo groves, as well as endangered species like the clouded leopard and Himalayan black bear. The trail is often mist-laden, with sounds of birds guiding trekkers deeper into the heart of nature.

Narpuh Eco Trail, Meghalaya

Trail Highlights:
The path cuts through dense forests with rare orchids, bamboo groves, and wild banana plants. Trekkers encounter natural limestone caves, bubbling streams, and rolling valleys that make the experience refreshing and unique. The trail is dotted with traditional villages, where Khasi and Jaintia communities still practise shifting cultivation and forest conservation.

Eco Value:
The trek is community-led, with local guides playing a key role in protecting fragile ecosystems.
