A little muddy after the rains, but still runnable. Moderate traffic especially in the first mile to each side of parking.

HikingGreat!

Very chill. Beautiful rolling hills. My wife, dog and I started out counter clockwise and then headed up to the steep summit via the paved road and then back down the narrow trail on the back side. Water fountain at the Trail Head. Would be hella hot in the summer I imagine without much shade.

A little muddy after the rain but not too crowded and it’s a great off leash dog area.

I took the Kovar trail first to hike along the ridge and see the sites. Then hiked the loop trail. There are so many trails you can take to make your trip longer if you like. Very peaceful. No traffic.

Partly shaded. Lots of woodpeckers. Not a lot of human traffic.
