The Patapsco River Trail is a white-blazed trail that has a number of interjected trails cut by vigorous mountain bikers. Start the trail from the park road where you'll see white blazes marking the woodland and rock entrance. This is a moderate hike that traverses a number of easy ascents and descents. The highlight of the multi-use trail is South Branch Rapids. There is even an overlook providing a wonderful photogenic view. The whitewater is very enticing, especially on a hot, humid Maryland day. However, swimming is prohibited, most likely due to industrial pollution. Interestingly, this is a good spot for viewing the statuesque blue heron. They are very common feeders along this stretch of the Patapsco River. As you hike the oftentimes-dense woodland, listen for songbirds that become apparent as traffic noise fades into the distance. Near the end of the path, a pavilion comes into view. It can be a welcome resting spot if not occupied. From here, take the park road back to the lot.
