Thrimshing La is a high mountain pass at an elevation of 3.682m (12,080ft) above the sea level, located in the Bumthang District of Bhutan. It’s one of the highest mountain roads of the country.
The road to the summit is paved in very bad conditions (even grael sections) and pretty steep, with hundreds of turns. The road is very narrow. It’s called Bumthang - Ura Highway and was built in the 1990’s. Notorius lack of oxygen that tests the organisms and a high degree of steepness. Extremely low oxygen for engine combustion. The drive is very hairy with some dangerous drop offs.
The journey offers superb views. It’s definitely worth it. The pass is often closed during winter for a day or two due to heavy snowfalls.
