"Nice trail that takes you out of the town and you're able to enjoy the landscape. Views are awesome! Definitely great for walkers, runners, strollers or bikes. There's some occasional wildlife that can be seen too. Don't let kids run off too much, wild boar have been spotted there too. There's a parking lot at the beginning of the trail, a picnic table and porta potty too."
