A beach in the river (no sand!), and water is really calm. There are umbrellas (for rent, but kind of free after 3p), boars, kayaks... Plenty of families and overall an enjoyable place. There is also a food truck with food and drinks (incl. Ice creams!). Parking is $7, but you can park in the street above and it will just be a 1-2 min walk.
Pros: excellent for kids and families
Cons: it is not a sand beach, but with little stones. Can't rest much when laying down!
