Bolton Notch State Park is a pretty little state park with one of the scariest entrances I have ever seen. You are traveling at speed down a turnpike and need to make a sharp turn into the parking lot. I'm not even sure how its legal but regardless, it's still worth a visit. At the park you can hike the loop trail, follow the trail by the pond, or to connect over to the Hop River State Park Rail Trail.
I stopped by the park while working in the area, just Olive and I on a sunny day with an hour to spare between jobs. The parking lot was small and served as a starting point for the state park or to jump on the connecting Hop River State Park Rail Trail. I jumped on Alltrails to see a 2 mile loop around the park and headed out.
The hike itself was pretty, a loop which took you to a vista and ended by the pond. Nothing to really brag about but a quiet park with some pretty scenery to stretch your legs and the option to log miles at neighboring parks. The section of the park that included the Hop River State Park Rail Trail was probably the prettiest, with these high walls on either side of the wide flat trail.
