Not into a 5k? Nursing an injury? Pushing a stroller? The 1mile walk is great way to show yourself some love while also supporting this great cause!
The Ironton Rail Trail connects nearly a dozen parks and two dozen historical sites in east-central Lehigh County. The rail-trail comprises a 5-mile loop around Coplay and Hokendauqua on the Lehigh River north of Allentown and a 4-mile spur west toward Ironton. Beautiful trail to walk or run!
The trail follows the route of the Ironton Railroad, which obliged the future trail makers by creating a lasso-shaped corridor to connect iron mines in the ore-rich county to iron foundries along the river and the Lehigh Valley Railroad.
