Visit the weekly markets. A large market is held on Thursday morning, breaking up at around 13:00 1 PM; a smaller market is held on Saturday throughout the day. The Thursday morning market is one of the biggest in the country.
Hire a bike railway station, head out over the old bridge, turn right, and pushbike along the most beautiful riverdyke, an oasis of quiet and nature. A gem mainly the locals know and really worth it.
