It was OK. Really nothing more than moderate. The only challenge was the constant uphill from the beginning of the yellow trail. Terrain on the yellow is mediocre at best. When I neared the top I jumped over to the blue trail. Terrain was a bit better, but nothing extraordinary. As you near the end of the blue trails southward direction from the top there is a lock box on your left with notebooks and pens. People leaving messages and tips for the next to come across it. That was pretty interesting. All in all, it's like a regular walk in the woods
I am not sure what 7.6 mile loop this is talking about. The Horseshoe Trail is a 140-mile trail that runs from Valley Forge National Historical Park toward Harrisburg, Pennsylvania. It ends about 15 miles northeast of Harrisburg at the Appalachian Trail. It does run along the Lancaster-Lebanon county line north of Lititz, but it is not a loop trail.
