A minimum of three days, but a week is more
realistic. Druk Path Trek: Paro to Thimpu is a short and
relatively simple trek but includes two nights at high
elevation.
Jomolhari Trek
Offers great high mountain scenery but crosses a 4,800 m pass.
Jomolhari Alternative Trek
Do the first three days of the route to Jomolhari Base Camp then
return to Paro via the same route. This avoids the high passes
but provides mountain views, highland villages and pastures.
