There's no night running allowed here, and it's one-directional (as shown). This trail is for winter-use only when snow-covered.
Christmas Trail is named as such because it looks like a tree laying on its side when viewed on a topographical map. The trail is designed as a set of back and forth dips with some tight turns and fun ups and downs. Toward the front half of the trail, there are two large jumps for mountain bikers.
The back half of the trail gets a bit more technical with roots and rocks where you'll want to watch your step. This is a really fun part of the Franke Park Trail System.
