Read this bit out
More than three hundred years ago, English settlers built houses here. The houses are long gone, but the holes where their cellars were are still in the ground, so look for a square dip lined with stones. The farm is still working today, and the cows here are milked by a robot. Each cow walks in when she is ready, and the robot does the rest.
One of your three free places, or the Explorer Pass. What that costs
Before you go
- Time there
- Plan on about 2 hours at the park.
- Parking
- The lot is at 165 North Road, by the farm. $3 a car from April 1 to November 30, whatever your plates say; free the rest of the year.
- Underfoot
- More than twenty miles of trails through open fields and woodland.
- Stroller
- A stroller works on some of it.
- Bathrooms
- There are bathrooms.
- Food
- There is an ice cream stand at the farm. Picnicking is fine, but there are no grills; DCR allows only a propane grill you bring yourself, no charcoal.
