Erwin Park is a great place to visit if you're looking to spend a few days running or biking trails. Campsites are far enough apart that you have privacy yet close enough that you don't feel alone. The park has several covered pavilions as well as restrooms but lacks shower facilities. A few of the campsites are drive up but most are park and haul. Each site has a picnic table, fire pit and trash can and some of the sites are more shaded than others. The trail network is about 9 miles and maintained by DORBA, these trails flood easily after rain so check the DORBA website before making the trip. The trails are straight forward and not super technical. Runners, hikers, walkers go one direction and bikes go the opposite. It gets pretty busy on the weekends with bikers so if you're on foot keep your eyes & ears open to avoid being in the middle of a pileup.
