Tsimasham is in Chukha district.
Tsimasham is the headquarters of Chukka district and is located on the main Thimphu to Phuentsholing highway. The town is somewhat barren and lacks any kind of charm or even cohesion. There is no reason to stop here, except perhaps to take a refreshment break.
All buses plying the route between Thimphu and Phuentsholing pass through Tsimasham.
