Nothing much in the area to see, IMO, apart from the amusement park (can't recall its name).
Have to disagree here. If you are into architecture, Reus (the old town) is one of the prime examples of Spanish 'modernismo'. In the vicinity, there are several wine growing areas, especially the Priorat (about an hours' drive) is well worth a visit.
As has been said, get the info off the AENA website. One more thing: if you come along the Med (from France), it's a good idea to program the Barcelona VFR route into your GPS as you might struggle to identify some of the waypoints. This runs from somewhere south of Girona overhead Sabadell (busy training airfield) to near Tarragona. From there you're a few miles from Reus.
