9/15/2018: Our group including 5 adults and 3 kids (ages about 5-11) all wearing regular shoes, made the trip up and back with time to stop for lunch and views in about 5 hours. It was a stunning day to be outside as it was nice and brisk but sunny. Bring a windbreaker though- it was downright COLD with the wind up near the top and out of the tree line.
Side note: It's been several days since our hike and my calves are still barking! As others said, it isn't overly steep, but it'll still get ya!
We'll definitely be headed back! (I heard the flowers are lovely mid-summer!)
