I would give this beach 5 stars, but with some reservations. The water is crystal clear and it's great to be able to swim with your dog. The only downside is that access to the water is narrow and the bank is shaded. It would be nice to have a few bushes removed so you can relax by the water with your dog. My dog always wants to swim when we're at the lake, so having a spot by the water to throw the ball is important.
I understand that the whole meadow can't be turned into a dog beach, as that would cause chaos. That's why I prefer to visit during the week or outside of holidays, when the rules for dogs are more relaxed. If the dog is well-trained and waste is cleaned up promptly, you can usually find a spot by the water.
The kiosk owner above the lawn is friendly and has a good snack bar. It's disappointing that schnitzel is only available on weekends, but it's still worth a visit at any time. 😉
