Within half an hour's drive south of St. Andrews, on the eastward-facing peninsula incorporating St. Andrews and Anstruther, is the district of East Neuk, dotted with some of eastern Scotland's most scenic and unspoiled fishing villages. You can't reach these villages by rail; the nearest stations are Ladybank, Cupar, and Leuchars, on the main London-Edinburgh-Dundee-Aberdeen line serving northeast Fife. Buses from St. Andrews connect the villages, but you'll really want to have your own car here.
If the weather's right, you can cycle among the villages along some of the most delightful back roads in Fife. Rent a bike at East Neuk Outdoors, Cellardyke Park in Anstruther (tel. 01333/311-929; www.eastneukoutdoors.co.uk). This same outfitter can also fix you up for a canoe trip.
