There are a lot of nice country back roads of of 521 and this is one of many. As you go through Rosharon make sure and stop and enjoy a cold beverage at the local bar. Once you leave 521 it's a nice country ride with wide sweeping turns and lots of straights. The park cost $5 to get in but I is worth it. Lots of curves and wild life to stop and see and the scenery is magnificent.
