We went up the Abol Trail (shorter, but steeper than Hunt) and down the Hunt. Both trails were fantastic. We went in July, and only saw one other hiking party on the way up - two obviously freqent hiker dudes, who left us in the dust. A strenuous hike, frequent very short breaks help.
The Hunt, the trail down, had more people, all of whom we met on their way up as we were coming down. Many of these groups included some who were not going to make it up, nor should they have been attempting the climb. The factors included out of shape to too young. One family had a kid about 7 or 8 years old who was freaking out big time. They were far enough up that he was going to have struggle to get back down. They were also faced with a teenage girl who made it clear she'd rather be at the mall. Physical ability, plus a desire to do the cliimb are musts for this to be fun.
The entire climb and descent took us about 7 hours. We didn't spend much time at the top, as it was foggy and we stuck to the white markers on the rocks like glue. We did get a couple of breaks in the fog to appreciate the scenery along the ways up and down. If scenery is your main reason to get up there, don't count on it. Fog and clouds can roll in at a moment's notice.
If you camp at the park, ask for Ranger Tom Bell - he is the greatest! He took care of the the Abol Stream Campground the night we stayed there, and was efficient and friendly, and offered us a lot of great advice, along with some fantastic stories of some of his adventures.
