After breakfast, drive to Dochu-la pass (3,088m/ 10,130 ft) to view Druk Wangyal Chortens with colourful prayer flags surrounding the area. With Her Majesty Ashi Dorji Wangmo Wangchuck’s initiative, these chortens were built to honour His Majesty the 4th Druk Gyalpo and his people for their victory in the war fought in the southern region of Bhutan in 2003 and for the benefit of all sentient beings. If skies are clear, the following peaks can be seen from this pass (left to right): Masagang (7,158m), Tsendagang bhutan(6,960m), Terigang (7,060m), Jejegangphugang (7,158 m ), Kangphugang (7,170 m ), Zongphugang (7, 060 m ), a table mountain that dominates the isolated region of Lunana - finally Gangkar puensum, the highest peak in Bhutan at 7,497m. Then drive back to Paro, follow the way back up the dramatic Wang Chhu and Paro Chhu river valleys, before crossing through Paro town towards the north end of the valley. En route visit Simtokha Dzong, the oldest fortress of the country constructed by Zhabdrung Ngawang Namgyel in 1629. The name Simtokha literally means ‘Atop a Demon’ and the legend associated with the dzong’s construction tells us that it was built in order to subdue an evil spirit that was harassing travelers in the region. Later in the day after checking into hotel, proceed to visit Ta Dzong, originally built as Watchtower, which now houses National Museum. The extensive collection includes antique thangkha paintings, textiles, weapons & armour, household objects and a rich assortment of natural and historic artifacts. Then walk down the trail to visit Rinpung Dzong, meaning (“fortress of the heap of jewels”), which has a long and fascinating history. Along the wooden galleries lining the inner courtyard are fine wall paintings illustrating Buddhist lore such as four friends, the old man of long life, the wheel of life, scenes from the life of Milarepa, Mount. Sumeru and other cosmic Mandala.
