There are a couple of 2 mile hikes and a 3 mile hike. If you look at the Summit metro parks website though you can see a list of all the trails.
Depends on how fast you walk and which trails. I'd plan to spend between 2-4 hours there. But my family like to go off trails and explore a lot.
By all means go off the trails and exore the many rock formations. It's really a neat place so close to the city! We took our grandkids there and we spent a good 3hrs there but we looked at and went thru everything.
At a usual pace, I'd say about an hour roundtrip. My girlfriend and I did it in two, but we were taking pictures and enjoying the scenery.
Trails aren't very long. 2-4 miles depending. The trail I did last time was only around 2.5 and was the biggest one i believe.
A good 1 hour. Maybe more
If you connect to the Chuckery Trails through the High Bridge Trail you can get quite an extensive hike, near 7 miles round trip.
