Nice horse jump park with trails shared by horses and hikers. You may want to bring the app or downloaded map because the trails can be hard to follow.
Porta-potties.
nice trail of you're riding a horse, probably better in spring time.
I hiked William Rickman Equestrian Center Entrance (on the east side of the park). It has a nice large parking area with a port-a-potty. Most of the trails have sign posts at the the trail head. I did not notice any blazes along the trail. The trails are wide to accommodate the horses. Open field & forested trails. https://www.montgomeryparks.org/resources/woodstock-equestrian-park-trails-map/
Started at the Moritz Equestrian Center parking lot and hiked Monocacy Loop, then Two Bridge trail, Greenberg Challenge Loop, and Stone Bridge Loop. Took the southern leg of Greenberg Challenge Loop back to Twin Bridge and back to the parking lot. Trails on the west side are mostly open around the perimeter of fields planted with corn and barley.
