Simpsonwood Park is named after Ludie Simpson who donated the land to the Methodist Church. This Gwinnett County park borders the Chattahoochee River, directly across the river from the Jones Bridge unit of the Chattahoochee River National Recreation Area. It has about 5 miles of unpaved trails, including an approximately 3-mile-long loop trail. Although the park land no longer belongs to the Methodist Church, its chapel remains and can be rented for events.

Note: The creeks on Google Maps and Openstreetmap seem to be slightly off. In the map below, I’ve attempted to include more accurate placements of the creeks. I think there may be some trail segments south of the creek, but all the trail segments shown on this map are north of the creek.
