The central park is beautiful and well-maintained, with plenty of benches for people watching. There is a Tourist Information Center in the kiosk in the middle of the park with maps, internet and information about the city. Across the park, the white-washed catholic cathedral makes for great photos. The old cemetary is an interesting visit, about a 30 minute walk from the center of town. It is a colorful and maze-like place. The tourist office can give you directions on how to get there. At the far end of town, there is a overlook with an OK view of the city. To get there, climb the 100+ steps to the top, where there is a replica Mayan statue.
