Whether you're in Germany or in the Netherlands, it's easy to catch a ferry to Borkum. This island town is north of the Dutch city of Groningen, and is between the North Sea and the Wadden Sea. Not surprisingly, there are not one, but two great surf spots on the island.
The nordstrand is simply German for north beach. The crowds are absolutely nonexistant at this sandbar and waves can travel 150 meters. The waves are clean and the swell is often 4 to 6 feet. This being the North Sea, longboards are highly recommended, but this is a must-surf locale.
Borkum's weststrand is a beachbreak that's similarly desserted. The piers make for some wonderful point breaks, but is best on windy days. Like its northern beach cousin, the west beach is easy to find.
Experienced surfers might want to try their luck at Eisbach. There are some powerful 8-foot swells that you can ride for 500 meters. Watch out for the thick crowds and be aware that there is some localism.
While Germany might be more famous for its beers, check out the surf, too. You won't be disappointed.
