There are five old wooden drum towers and a few old wind and rain bridges scattered throughout town. They're best discovered by wandering through the back streets.
You can hike through the rice paddies above the town. Guest-houses will be able to help with directions. The walk up the valley is particularly picturesque.
There's a lovely 3km walk from Zhaoxing up to the nearby village of Jitang ç´å . And it is consistently uphill. They've a drum tower, nice old houses and a lot of peace and quiet and the villagers are lovely. There is at least one home-stay open there too - ask at the shops near the drum tower square for directions. The route from Zhaoxing is reasonably well signposted. Exit the village at the south east gate then follow the signs.
