The trailhead starts in the Timpooneke campground parking lot in American Fork Canyon. The cost is $6 per car. You can pay at the parking lot- there are self-pay envelopes. If you don't have cash, like us, we stopped at the little guard shack at the mouth of AF canyon on our way out and paid. We hiked to the summit August 1 2018. Weather was perfect. We started the trailhead at 5AM and made the summit around 8:30. We hiked quite quickly and large groups or inexperienced hikers would definitely take longer. Average is around 4 1/2 hours to reach the summit. We took 3 liters of water each and it was more than enough. If it had been warmer we may have needed more- but we were back to our car by noon. The hike down took about 2 1/2 hours. We had read that it normally takes a little longer. We also took snacks- which were needed! Snickers bars and peanut m&ms were perfect. The hike wasn't technically difficult so much as just long. It definitely takes endurance. It's not for the faint of heart. I'd recommend being in good physical shape- 7.2 miles each way. The views were breathtaking. Only the last mile from the saddle to the tippy top had some scary heights. If you're afraid of heights, the last mile will be a little nerve wracking. However, it wasn't incredibly dangerous. I'm not a risk taker and I felt pretty safe. It got a little hot on the way down. I wouldn't recommend starting much later than 5am because it can start to get pretty hot as the day goes on and you'll be tired . And the top of the summit can be quite cold in the morning. I had a sweatshirt with me and was grateful for it! read more
