This hike is physically and mentally challenging, but well worth it!! I feel like if you want to do it you can. I don’t work out and I was able to. Bring a good amount of water bc the hike up the wiggles can get you a little out of breath. If you are doing the chains I recommend having a backpack if you are carrying any items. Also, I think it’s a good idea to make a decision about the chain portion once you see it in person. The views are breathtaking and rewarding ! I definitely felt accomplished after this hike. Get there as early as possible. After parking and taking the shuttle, we got to the trailhead around 8:30am and it took 3 to 3.5 hours round trip. The trail was way busier on our way down, which was around 10:30am. Also, the trail can be a little hard on the knees.
