The Taktsang Monastery, or otherwise known as Tiger's nest, is one of the most crucial and popular things to see while in Paro. The monastery is perched on the edge of a granite cliff, approximately 3000 meters above sea level. Locals are expected to go on a pilgrimage to the temple at least once in their life time. The trek to reach the top will usually take about 2 – 3 hours. Located about 10 kilometres from northern Paro, a visit to the temple makes for a great day trip. Covered by lush pine forests and painted with beautiful sceneries, the hike up to the monastery offers a breathtaking view of the surrounding landscapes. The cave is considered to be the most sacred site in Bhutan, and it is believed that in the 7th century A.D. Guru Rimpoche, who meditated here, flew to the top on the back of a tigress and in order to overpower the demons that resided here, meditated for 3 years, 3 months, 3 days and 3 hours.
