Mt. Medaris is the approximately 600’ rise that separates historic downtown New Castle from the newer development to the north. For easiest access to the trail, take C avenue north from Main Street to the trailhead parking lot.
For an easy hike with no climbing, keep to your right and skirt the southern edge of Castle Valley Ranch. If you drove to the parking lot, you’ll need to retrace your steps. Otherwise you can exit the trail at the west end near New Castle’s senior housing.
To hike the ridge of the mountain, take the first branch of the trail to the left. After a short steep climb, you’ll get to the top and can view both the old section of New Castle and the newer development.
At the west end of the mountain there is a difficult route down toward the trail that leads to the senior housing complex. It’s easier to retrace your steps back to the parking lot.
