***MAP ALERT*** I contacted the Park Ranger and got these directions to the shelter coming from Richmond, as the map above seemed a little iffy:
"The shelter is at the entrance of Spotsylvania Battlefield off of Brock Road (613) and yes there is parking. There are multiple ways to get there. I95 north to Exit 118 Thornburg then west to 208 Courthouse Road and make a right going north through the small town of Spotsylvania Courthouse.
Continue straight through and it becomes Brock Rd. A couple miles from the Courthouse you should see the entrance to the park. You can also go to nps.gov/frsp for more info and other directions from the other battlefields. The directions I gave you is the "back way" which is more rural but most direct from Richmond."
I'll be at the shelter the battlefield around 10:30am - as long as there is fair weather. There's about seven miles of walking tour...will probably do all of that and plan on being out there several hours.
