Rock Run Grist Mill Trail is a 6.1 mile heavily trafficked loop trail located near Havre de Grace, Maryland that features a river and is rated as difficult. The trail offers a number of activity options and is best used from March until November. Dogs and horses are also able to use this trail.
Go up Rock Run Road to the split and enter on the orange trail. Follow the orange trail until it meets with the blue trail at the end of the farm field (the second time the orange trail meets the blue trail). Turn left on the blue trail, watching for trail spur #4 on the right (about 1/4 mile). Take the trail spur to the red trail; turn left. Take the red trail to the picnic area, where it will join the green trail. Proceed straight on the green trail; do not turn to the left. Follow the green trail until it crosses a small road to the campground area. Go straight on the trail spur #3 to the blue trail. Jog to the left across the creek. Turn right on the blue trail. Follow it all the way until it meets the orange trail. Turn left and follow the orange trail as it goes to the left, leading you to the road. Follow the road downhill to the parking area.
Great trails, Great site seeing. friendly people.
Pretty easy trail. Quiet and beautiful. I just can't seem to find that big tree.
Been here many times...brought my new puppy to get him started on a familiar trail....he did great! trail needs a bit maintaining...trees across path and large roots sticking out...and dont go after a big rain....we slid down a trail! overall...great trail with beautiful views
Great trail, wish it was a little more kept up on but beautiful sights none the less
My 4 year old son and I did just the Rock Run Trail loop where it uses the Land of Promise Trail to complete the loop. We also went down to the falls off the Historic Walking Trail. It's a moderate difficulty trail in my opinion. Keep an eye out for the roots and rocks. We did about 1.8 miles in an hour and twenty minutes. I forgot to continue recording after our lunch break so the time and distance on the track is a bit off. We had a good time, crossed paths with friendly people, and enjoyed the beautiful weather.
