In summer, it's just a great place to relax in the city, you can swim, sunbathe, eat and drink, and there are sports grounds nearby. Large parking lots nearby, you can always pack a car. There is only one minus - a lot of people.
Nice place, clean, fresh. There is a place to eat, you can rent bicycles and go around the whole lake. But you need to take into account that the taxi had to wait 30 minutes to leave.
