A steep incline for most of the trip, but well worth the time. The trail is not marked well, as you can follow the blue blazes until the end of the Belfast Trail. Continue to follow the trail, using the suggestions listed on the map.
The hike itself is not that long, 45 minutes by yourself, an hour and 15 minutes with a family. You will definitely want to plan time to stay at the marble yard and explore.
Directions to trailhead

Where did this all come from, you ask? The answer is found in a geology question. The Antietam Quartzite found at Devil's Marbleyard (Arnold's Valley) is the result of a rise in sea level relative to the land (transgression), over 500 millions years ago. Then a pure quartz beach. This might help you believe it. The blocks and boulders at the Marbleyard have tube-like structures running parallel to one another. Likely, these are the fossilized remains of cavities where a worm-like creature lived.
