I am planning a family vacation for July 12. From Nashville I would like to hit one of the more spectacular waterfalls in Tennessee before reaching our destination of Cleveland. I have been looking at Burgess, Cummins, Fall Creek, and Rock Island. Since my husband, 21 yr old, and 16 yr old are not quite as passionate about waterfalls as me, I am looking for the most spectacular, even in July, but also those that involve the least driving/hiking. I think Cummins Falls look gorgeous, but I keep seeing the quote from Travel & Leisure mag. about getting to it. I was wanting to hear from others just how bad it would be to get to for reasonably in shape 50 year olds. Or or others better? Thanks for your input!
