There are some areas near WRP to park.
You can park at the Magruder's/CVS plaza on Kemp Mill.
The trail is just behind their plaza....to the right is Wheaton Regional Park, to the left, you cross University Blvd. and head on into Silver Spring and beyond.
Folks also park at the lot on Sligo Creek Parkway at the intersection of University Blvd.
You'd also be welcome to park at our house and ride down Randolph to Kemp Mill to Arcola to pick up the trail (3 miles on road).
