The drive is longish - like 45 minutes, the hike (at the very top) says 2 miles round trip but my fitbit logged 3.7 miles round trip. That took 40-50 minutes out and 30 minutes back. Up is up up, and w some narrow areas. Back in is downhill mostly and easier/shorter since you’re not stopping as often. I am from Texas (sea level) and been in Utah for 3 years - I got winded when walking fast; it is steep and high in elevation. There are no fences or railings except at the top. There are 16 markers - the first 9 go slow but after that theyre closer together) There are 2 benches (1 bench after 7 and I don’t recall the other sorry).
All said... the drive + hike is 1,000% worth it!!!
Ive included some photos of the outlooks (escallante), during the climb, and the top of Harpers Corners Trail.
