National Express buses serve the region from London's Victoria Coach Station. Most of the larger towns can be reached this way; journey times vary from less than two hours (Canterbury) to more than three (Chichester). Megabus runs buses at budget prices from Victoria Coach Station to many of the same destinations as National Express and can be cheaper, although luggage limits are strict.
Bus service between towns can be useful but is often intermittent. Out in the country, don't expect buses more often than once every half hour or hour. Traveline is the best central place to call for bus information, and local tourist information centers can be a big help.
