There's a map posted as soon as you turn off the road onto the trail. 3 or 4 shortish loops. Not well marked. It's a fun ride and close to Towson and Baltimore. Connect a few loops for a 30-45 minute ride. Somewhat strained vibe with others who use the park but it is designated multi-use (to "protect" the park, some areas have signs spraypainted on trees "no bikes" - one even says "no dikes").
