In the Old Port area, this is a small strip of land with clean sand, some provided umbrellas and a bar with offerings. You can sit on the steps or just hang out for no charge. Electric scooters are available nearby to rent. It is for sunbathing only since you aren't allowed to swim in the river. Their website has a PDF of rules and hours. There's a larger Pavilion nearby with more food and drink options, but no sand. The Clock Tower itself is worth a climb (also free). Only 190 steps, and it does become narrower as you get to the top. View from the top is pretty good!
