It's a local runaway place, mostly visited during weekends by locals living in the capital. It's well maintained, clean and a nice place to visit, relax by the water in summer.
Many options for a boat tour, have a look around before deciding. Cruise is nice, houses alongside the river are cute and there's a beautiful farm at the end!
To see the sunset go on a boat. You'll be surrounded by beautifully reflected lights. It's beautiful from the shore as well, where you can see all the colors.
