In this installation of Better Know a Trail, we have the Eastern Promenade Trail. Appropriately located along the peninsula's Eastern Promenade, the Eastern Prom Trail is truly one of the city's premier outdoor spaces. As you can see by the map and description of the trail on the Portland Trails website, this trail is 2.1 miles in length and well connected with the Back Cove Trail and the Harborwalk Trail.

The Maine Narrow Gauge Railroad runs along a good stretch of this trail:
Fans of the Eastern Promenade should check out and get involved with Friends of the Eastern Promenade, a "nonprofit community organization committed to preserving the park's historic public landscape, protecting the environmental integrity, and enhancing recreational use."
