Set on the banks of the Pachhu, at 2,250 meters (7,381 feet) above sea level, Tachog Lhakhang rests quietly—just 6 km (3.8 miles) from Chuzom and a 10–15-minute walk from National Highway 1. The name "Tamchoe" derives from Yidam Tandrim, also known as the brilliant horse of Guru Rinpoche, which is believed to reside near the river.

The temple was founded in 1433 by Drubthob Thangtong Gyalpo, also known as Tshonder Zangpo, the iron bridge builder invited by Ap Chundu and Jowo Drakey. It was here that he first returned after his long meditation, greeted by a celestial woman to whom he offered three blessed pills before vanishing once more.

Though damaged by an earthquake in the 1980s, the temple was lovingly restored by Choejey's descendants, preserving its soul and story. The surrounding area, with iron bridge remnants and swirling prayer flags, whispers tales of saints, spirits, and seekers.

Visitors crossing the iron chain bridge—one of Thangtong Gyalpo's brilliant innovations—step into an atmosphere steeped in history and reverence. The carved wooden panels faded murals, and incense-laced air carry echoes of Buddhist chants and Tibetan opera, believed to have originated with the master himself.

Often visited from Paro to Thimphu, this temple offers more than a scenic stop—it is an early spiritual embrace of Bhutan's cultural journey, connecting the mystic past with each traveller's unfolding story.
