Head to Houston Wilderness Park March 12 at 2:00 p.m. for their weekly Sunday Fun at the park. Every Sunday afternoon, will be a different planned activity to get you and your family involved. From archery to fly fishing, to everything in between, come join the park staff! Events will be posted on the Nature Center events board each Saturday morning. The program is free, however, there is a $3 fee to get into the park. Houston Wilderness Park is the only park in the Houston Parks Department that has overnight camping facilities. It was originally a state park until Houston took it over about 10 years ago.
