High Point State Park, NJ
High Point is a State Park so there is an entrance fee when you arrive so make sure you have cash on you. There many trails for you to hike and there is a lake for you to swim in as well. I hiked the monument trail and is medium strength hike because it does require going uphill but also has some flat areas during the trail. It is about 3.7 miles and it starts at the Monument parking and then follow the red/green trail and brings you to the top where the Monument is. You can also bring your dogs here.
