Paro Taktsang (Tiger's Nest)

Tiger's Nest is a sacred Buddhist site and perhaps Bhutan's most famous attraction. It is both a hiking adventure and a spiritual quest, culminating in a temple complex consisting of 13 monasteries hanging off one side of a cliff, rising over 9,600 ft (2,926 m) above sea level. Built in 1692, the monastery is dedicated to Guru Rinpoche, who spread Buddhism in Tibet. He is believed to have flown to this location on the back of a tigress and meditated in the cave for three years to tame a demon. The name Tiger's Nest comes from this legend. 

On average, the hike takes 4-5 hours (alternatively, you can rent a horse or mule to ride uphill). There is a cafeteria at about the halfway point where you can rest, have a snack, and use the restroom. The second half of the climb is less steep, bringing you to the famous viewpoint where all the amazing pictures are taken, and eventually leading you down a stone staircase towards the base of the temple complex. Photos are not allowed inside the monasteries, so you must leave your belongings in the safe lockers outside the temples. Tiger's Nest opens at 8 am. Get here early to avoid some of the crowd. Hiking poles can be bought at the site's entrance.
