Where do we go if we want to bike the trail? Where do we park, and how long is the trail. Thanks.

This is the place cross a street and the tracks and there you are you can go either direction for many miles (more to the right)

Brilliant Station is pretty much a parking lot, there isn't an actual station. The trail is right next to the lot. Not sure how many miles it is but it's impossible to bike the whole thing.

The trail's website has good maps and information. https://yorkcountypa.gov/parks-recreation/the-parks/heritage-rail-trail-parks.html

There are multiple places along the trail with parking lots depending on where you want to go. It goes from John Rudy park in Manchester to Parkton Md
