Mangde Foot Trail Trongsa – Old Route Hike

By: AD Tours on March 13, 2026

Before the construction of Bhutan’s East–West Highway, Trongsa Dzong served as the main gateway connecting western, eastern, and southern Bhutan. Travelers, traders, and monks once used an ancient trail—now known as the Old Route Hike—to access the dzong from the valley below.

This historic trail begins near the viewpoint overlooking Trongsa Dzong and descends toward the Mangde Chhu, the river flowing through the valley beneath the town. In the past, travelers crossed the river using a traditional Ba Zam, a wooden cantilever bridge built using ancient Bhutanese engineering techniques. Although the original bridge was once washed away by the river, it has since been rebuilt to preserve the historical route and improve access for locals and visitors.

Today, the trail is known as the Mangde Foot Trail, a scenic and culturally rich hiking route that follows sections of the Mangde River and winds through lush Himalayan forests of pine and rhododendron. Along the way, hikers enjoy beautiful views of the surrounding mountains and valleys while passing small rural settlements where traditional Bhutanese life continues much as it has for generations.

The trail also features several cultural landmarks, including small chortens (Buddhist stupas), prayer flags, and traditional cantilever bridges that reflect Bhutan’s architectural heritage.

The hike concludes with a gradual climb back toward the majestic Trongsa Dzong, one of Bhutan’s largest and most historically important fortresses. Perched dramatically on a ridge overlooking the valley, the dzong once controlled the strategic trade routes between east and west Bhutan.

This moderate hike offers a unique opportunity to experience Bhutan’s natural beauty while connecting with the country’s history, culture, and traditional village life.
