Ultramodern and resolutely traditional, China is a land with one foot in the present and the other striding into the future. This eight-day adventure connects them both, beginning with Shanghai s sleek skyscrapered skyline. Then, you ll strap on your boots and hike into the countryside around Longji to wander the picturesque rice paddies. (Depending on the season, you may even get to help out with the harvest.) See the limestone karsts of Guilin before you return to modern times with a two-day stint in always-on Hong Kong. Nature and modernity, in perfect balance.
