Pineland Farms is a wonderful place to bring your family. It's a 5,000 acre commercial farm with over 18 miles of trails. The trails, designed for cross country skiing in the winter are also open to mountain bikers in season.
There's a fee system, $5 for a day pass or $40 for a year.
There's some climbing and it's quite scenic. It's a great place to ride with your family or, to bring a newer rider.
There's a farm store and lots of kid's activities. So it's possible for mom or dad to drop the kids off, go for a ride and then return to pick up the kids who will have had their own, more educational, adventure.
