It is a short drive of approx 20 minutes up the Paro valley to Drukyel Dzong, which was originally built as a fortress in 1647 to guard against Tibetans invading the Paro Valley. We continue the drive to Shana (1-1.5h drive) from where our trek commences. On this scenic drive we pass through farm country made up of fields of rice, wheat, barley, mustard, potato, and radish as well as herds of cows. The traditional Bhutanese two storey, timber and stone houses can be seen here. We also gain our first views of the summit of Chomolhari (7314m) at the head of the valley. We get under way and take a break for lunch where it suits us, as we are carrying a packed lunch. Initially the trail is wide and flat, as it meanders steadily through lightly forested fields, which in recent years have been the site of the ongoing large-scale Bhutan Government project to bring electricity to the isolated villages further up the valley. It is a reasonable day's walk today, our first day's trek, taking us past Overnight camp Thongo Zampa.
