You can park directly on the beach in St. Peter-Ording. A great experience. You can then explore everything else on foot.

Don't be confused by the map guidance here. You can, of course, go directly from the car park at the beach to the restaurant. As long as you are at the beach and the sea is on your right, you are going in the right direction.
Why wait long and pass the time when you can go straight to the highlight in St. Peter-Ording for an early lunch. On the one hand, you should be strong enough for the extensive beach walk and also relaxed enough. Have a good time! The view is breathtaking and so is the food. Take your time.

Here too: Don't be confused by the map guide here. When you walk out of the restaurant, the sea should be on your right. You can't miss the bridge, it's on the left and leads into the small town of St. Peter-Ording.

Here you will find the best cakes in the whole of St. Peter-Ording. And if you're now wondering why you should eat again? Let me tell you, the fresh North Sea air will make you hungry. All the time.
Closed Tuesday and Wednesday.

Are you in love? Why not hang up a love lock? There are not many places as unique as the rugged town of St. Peter-Ording.
If your love lock holds up here, in the harsh North Sea air, so will your love story.
If you like, you can take another walk along the beach or head straight to the world-famous Gosch restaurant for some ‘Weinschole' (white wine and soda).

Whoever is at Gosch gets a great experience. You might be a little surprised at first why you have to pick up your drinks yourself at the bar and also the food is ordered at the bar and then picked up yourself later. But once you have done this, you can breathe in the ambience. And no restaurant can top that. Let it carry you away and enjoy the great fresh fish dishes. Don't worry if you don't like fish, there are also meat or vegetarian dishes. But in any case, you shouldn't miss an evening at Gosch. Take your time and soak it all up.

After dinner, take a nice walk back to your car. You decide whether you want to walk along the beach or back through the city. You will need about 30 minutes for both.
You can also pick up your car earlier and park it in the small town centre of St. Peter-Ording. You'll find plenty of parking spaces. They are all not that cheap, but then you won't have to walk far after dinner. The decision is yours.

With lots of fresh air in your lungs and great food in your stomach, it goes back to Hamburg.
