The caves were easy to navigate since there was a tour guide and paved walk ways. It was just under 2 miles so my kiddos 6, 4, 2 were able to do it. My 2 year old got tired towards the very end and hubby had to carry him. I was also 37 weeks pregnant and did just fine.
The trees were still mostly bare and we didn't do any of the trails. We stopped at a few overlooks but mainly we just wanted to check it out since it was on our way. Next time we will have to plan to do some hiking!
