Located 76 miles (122 kilometers) to the east of London, Dover is a major passenger cruise port (as much for cruise ferries as it is for conventional ships) that's considered England's gateway to Europe. Dover is most commonly a port of embarkation and/or debarkation (itineraries can vary, from those that head to the Baltics and Northern Europe to those cruising south, to the Mediterranean), and most cruise passengers who want extra time in England will use London as their base instead. London is about a 1 1/2-hour train ride or two-hour drive away. Dover's proximity to some major southeast England towns and villages means there are alternatives to big city touring as well: Rye, a 1 1/4-hour drive south, is a charming medieval village and the city of Canterbury is noted for its awesome cathedral, among other sites. For day trips, Sissinghurst, Vita Sackville-West's famous gardens, are near enough to tuck into an "on the way to the port" sightseeing jaunt, as is Leeds Castle.
