“This is a dirt singletrack trail which parallels the paved trail in Holmesbrook Park
— Ron Kyle
It's in a popular park and it's a mountain bike trail; they should just be cautious.
As you enter the park along the normal paved trail, you'll see a sign on your left saying "Bike Trail" and pointing to a narrow trail which immediately climbs. Keep climbing, but watch out because you'll soon encounter an extremely large log across the trail in an inopportune place after a tiny descent. Don't run into it, hop it if you can, or more likely step over it, then continue on.
The rest of the trail is easy, with a few minor obstacles here and there. Soon the trail descends and exits the woods through a bit of sandy ground, meeting back up with the paved trail. That's it - this route is short and sweet!
