Hi, I'm considering camping at Nolin Lake State Park at the end of June and am wondering how far it is from the national park - according to a Tripadvisor review, it's only 10 min away - "Mammoth Caves are just 10 mins away and you take this little ferry to get your car across the river to get there.( It's free) I was fascinated by that!" (tripadvisor.com/ShowUserReviews-g39177-d1018…) but according to Google map, to the main park visitor center, it will take 1 whole hour!
Who is telling the truth? I certainly don't want to drive 2 hours round trip every day.
Thank you so much!
