On the Elkridge County side of the Patapsco ( Howard County ) are multi trails that can be hiked in many ways. There are a few connector trails you can take if you wish to add or minus the miles of your loop. You could also have hiked the Cascade Falls trail which is color coded ( blue ). This trail does get crowded on weekends. The entire trail system is well marked and color-coded, except for Garrett's Pass but I would recommend a map as a backup. It felt great to get out after a week of high humidity. A few little showers were fine but now the rain comes. Stay away from the Swinging Bridge or the Restroom when saving your data. Park on the big lot and save data there. The other location is a dead spot.
