Hello, we are headed to GNP in the summer of 2014. My family and I love to hike. I was wondering if anyone had every taken kids on the highline? I understand there are a few signifiact drops just feet away. My son has hiked Mt Washburn in Yellowstone at age 8 and a 8 mile round trip hike in the Tetons. He will be 10 when we head up there. So, anyone ever take small children on the highline? Thanks for any insight.
