Insider tips:
If you fancy a trek near Thimphu in winter, the following two trekking routes with their starting places not far from Thimphu are not recommended to challenge during the winter
1. For the Snowman trek, winter is not an appropriate time for most of the locals and trek lovers to challenge, for trudging off through the whirling snow in some high altitude areas is as dangerous as you choose winter to climb up the Mt. Everest, for some snowbound trials may lead you to untouched areas with no backups but all uncertainties.
2. It is also not wise to plan a Jomolhari (Laya Gasa) Trek in winter due to the high altitude and steep ascents and descents along the higher parts of the route trails.
