Plan to visit Brendene, the only nude beach in Belgium.
Expect to find a small beach that's about 200 meters long.
Be prepared to deal with the crowds if you decide to go this beach on a hot, sunny day.
Do not wander into the area behind the nude beach if you do go on a crowded day. This area is the clothed beach.
Take the tram towards Knokke to get to Brendene. Exit the tram at Renbaan and then follow the signs to the beach.
