Nice hike with the kids. They really liked the bridges and lookout points. I prefer a little tougher retain, but this is perfect for when we bring the kiddos along. It is a bit buggy, so I highly recommend putting on some bug spray before heading out.
Beautiful park, well maintained, level, gravel paths. It felt very safe. I've been a few times to walk the paths. I wouldn't really call in "hiking", although you can certainly turn into a 6 mile walk if you zig-zag through all the paths. I like to walk the park, then walk about 2 blocks to downtown Smithfield for an ice cream cone afterwards. :)
A really nice trail in a nice park. It is strictly a bike path with pedestrians not allowed. Sadly, it seems to be underused, judging from all the spider webs and the lack of tire marks. The park map shows it as a perfect circle; not even close. It zig-zags around the park inside the 3 mile pedestrian trail.
Enter the park from Mason Street. There is usually free parking on Sykes Court and the neighbors are nice. Keep left until you come to Jericho Road then turn right and follow it around to the park headquarters. Then exit right on the trail back to the trail you came in on.
