I will be in Asheville on July 26th and 27th for a metting @ The Renaissance. This is an overnight stay and hubby and 2 y/o will be traveling/staying with me. The meeting ends @ noon on Friday and we will be moving on. We would like to go to Sliding Rock on Saturday. I am not making reservations for sleeping on Friday night, because we will stop whenever. My question is take the Blue Ridge Parkway or go to hwy 280 and what is the testimated time frame from Asheville to the "Land of Waterfalls"?
