The Coast Tram (Kusttram) is simply the best way to get around the Flanders coast between De Panne and Knokke you can find. A five day ticket is only €15 and that also includes all buses run by DeLijn. There are shorter period tickets too. Unlimited travel means just that. Up to end of August the service is less than every ten minutes in each direction, after that it's a bit more but we never waited very long and there was always plenty of room on the trams. The Tram Shops (Tramwinkel) sell tickets and give out maps and lots of information. Stops are very convenient to towns and attractions and seaside, so you are never far from one. Indicator boards give information about what's coming and how long it will be. Couldn't be more convenient.
