That sounds weird .... Nan Old Bus Station .... yes old but actually still in use for the local regional busses like the
Orange Bus and the Blue Bus. Although this busses are also using the normal Nan Bus Station, but their original starting point is the old bus station of Nan. It is located along Ananta Woraritthi Det Road, right next to Nan Municipal Food Market. If you want to take one of the busses that are leaving from here you might be better of going to the "new" Nan Bus Station. For more information about Nan province see Destination Travel Guide Nan.
