A couple of my friends and I biked the length of the Lower Trail and then back again last weekend. This is a rail trail that claims to be 17 miles long, but I mapped it out at just under, so the full trip ended up being around 33 miles. The trail is super flat and easy, very friendly to anyone! My favourite part was the beginning of the trail, near Alfarata, where it feels like the forest stretches forever on both sides. That illusion quickly disappears when you get closer to Williamsburg, and you even pass a gas station at one point!
I got a little ahead of my friends and stopped to take some photos of spring ephemerals and bees (of course).
