The trail itself is great. It is a moderately cleared trail with spray paint markers on the trees every ~30ft. I never felt like we couldn't find the trail when hiking. Lots of hills through the area.
Of note, the trail route pictured is not the location that google maps will take you to for the south trail head.

Nice quiet trail even though there were several cars parked at the trailhead. If you're walking beware of horse manure. Watch your step. Otherwise very scenic and shady. You will need the bug spray if hiking in spring/summer. In some spots the trail is not very wide so be careful when bikers are passing. Wear good shoes as some parts are very rocky and can turn muddy.

This is a great trail for cardio and working your legs out
