Parking is available at the Glen Cove Marina. However, the first section of the blue blazed Mason Dixon Trail, when proceeding north, simply follows Glen Cove Road uphill to River Road and still uphill past the Indian Hill Christian Service Camp. I opted to skip the road hiking and parked on River Road just past the Christian Camp. There is a good view of the Susquehanna at this point.
The Mason Dixon Trail is well blazed (blue). At times I found it easy to lose the trail and was forced to back track. Pay attention to double blazes which indicate a change in direction and don't hike too far without seeing blazes.
From the Christian Camp the trail follows a woods road down toward the river where it intersects (0.3 miles) with a woods road which runs parallel to the river. The trail then follows this woods road with a long slow climb and then intersects with a power line (0.5 miles). It then follows the power line along a well mown path. Unfortunately, in this area, the trail is open and it is a bit discouraging to see the hills you will climb ahead.
At 0.75 and 0.85 miles there are camps with no apparent access other than via the river. The power line goes from a single pole to three pole structures, a sure sign of a long span to cross a stream.
Sure enough, the trails descends and enters the woods and crosses a stream with nice cascades at 1.0 miles and climbs through the woods past another camp where the owner has jokingly posted a "4009 River Road" sign on the trail. At 1.3 miles the trail crests and then descends and meanders into the woods (1.4 miles) to a locked gate with a pretty clear "No Trespassing" sign. However, the trail cuts along the hillside and at 1.7 miles intersects with a woods road which accesses a camp which is orange in color. At this point, I didn't pay attention to the double blaze and followed the road down past the camp and along the power line, but realizing there were no blazes, retraced my steps to the intersection.
The trail continues along the side of the hill crossing a number of boulder strewn areas (1.75 miles). Some of the rocks are interesting in that they are scratched in two directions in a cross hatch pattern. The trail gets better and crests at 2.0 miles in a pleasant mix of woods and field high above the river. A woods road leads down to an undentified dirt road (2.25 miles). The dirt road which is well traveled leads down to Broad Creek Park.
Rather than continue to Broad Creek, I hiked south along this dirt road to Flintville Road (2.5 miles) and then south along Flintville to Castleton Road to Glen Cove Road near Peddler Run and then to River Road and then back to my vehicle (4.7 miles). Hiking along Flintville and Castleton was difficult for me as Maggie, my beagle was far less exhausted than I was and was straining at the leash the entire way.
Grey Rock Farm on Castleton Road includes a stone home, a number of stone outbuildings and a barn set between two banks. I also noted a lone chimney just south of the farm on the west side of Castleton Road. There are ruins of a relatively large stone structure at River Road and Peddler Run.
In returning to my home, I happened to note a stonewall that must be a quarter mile long along the east side of Franklin Church Road. These are of course commonplace in Vermont where boulders littered the fields and the "walls" were refuse piles, but they are not all that common for any but the wealthy in Maryland. There is an interesting barn on Paddock Road near Franklin Church Road and Love Road off Franklin Church Road is a road lost in time.
