Taktsang! A.k.a. Tiger's Nest. One of the most epic and most recognizable sights in Bhutan. But while not everyone will be able to make the climb up, everyone should at least visit the base, from where you already have an epic view of Tiger's Nest.
So, especially for those not up for the whole hike, we placed a geocache at the base, just a short walk away from the parking area (right after the horses). Please make sure it stays well hidden!
