Read this bit out
This forest keeps changing its mind. One minute you are under oak trees, and a bit further on it is nothing but pines. Listen for the moment it goes quiet under your feet — that is the pine needles, and it means the trees have swapped over.
One of your three free places, or the Explorer Pass. What that costs
Before you go
- Time there
- Plan on about an hour and a half at the park.
- Parking
- Park behind the soccer fields at 105 Mill Road. There are two more ways in from Noble Drive. Open dawn to dusk.
- Underfoot
- Densely wooded, alternating oak and pine, with three thousand feet of pond frontage. Mountain bikers use the trails a lot, so keep little ones to the side when bikes come through.
