Date 1/11/2017 Great Hike and nice views of the river.
Excellent for bikes! Long paved trail that runs along the river. Optional side hiking trails off to the sides. Easy to make a day of it.
This was a very nice trail. The weather was absolutely gorgeous and the temperatures cool. Went during weekday so wasn't too populated. When we got to the very end where the suspended bridge was we were about to turn around and walk back. There was a guy there that said there was another way if we were interested. We were. We prefer new trails instead of backtracking. We crossed the bridge and made a left and walked up the road about 100 feet. To the left, over the guard rail there is another trail. It is not maintained. It is not recommended for dogs, children, horses or after heavy rain. Rocky and rooty with several trip hazards so be careful. Some areas are steep down and up. After several hundred feet, you'll find yourself on a more maintained trail. This will be down by the dam. Keep river on your left and keep going until you see the very first suspended bridge. We crossed back over that bridge, made a right and followed the Gristmill trail back to our car. If you don't cross over the bridge and continue straight you'll be on a traveled road. We did not want to be on that road. So we just crossed the bridge and got back on the trail. Coming back that way made for a much more strenuous, experience.

Good trail for walking and biking. Great birding area. It is beautiful in all seasons. I like the Lost Pond area.
Starting in the Avalon area of Patapsco Valley Park near "Lost Lake", this is about 2.5 miles long, ending at a suspension bridge across the Patapsco River at Illchester Road. Near the trail end at Illchester also features the Illchester Train tunnel and ruins of the of the old St. Marys College, a former seminary. Entering the Avalon area of the Park, you will also see the Thomas Viaduct, built in 1835 it is the world's largest multiple arched railroad bridge with an arc and is still in use by trains today. Other highlights off the tail are a swinging bridge at Orange Grove and the remains of the Bloede's Dam (scheduled for demolition in late 2016) which was the world's first submerged electrical generating plant contained inside a dam. There is a small fee for entry into the Park.
