Visiting Bhutan in January was like walking into a winter fairytale. The Bumthang trek exceeded all my expectations—peaceful trails, ancient temples, and warm hospitality in the freezing cold! Despite the chill, the sun shone brightly during the day, making the treks comfortable. I especially loved the Tang Valley section—remote, spiritual, and untouched. If you're looking for solitude, culture, and raw Himalayan beauty, January in Bumthang is perfect.
