We have been going to St. George at least once yearly for over 35 years and never knew this place existed until I saw it on Tripadvisor. It's very close to the city and it's free - what could be better? You get there by going up Main Street then turning right and following the road past the "Dixie" rock to the parking area. When we were there there was a group of rock climbers with ropes and such climbing the face of the "Dixie" rock itself, but also many people young and middle aged walking all over the other rocks and enjoying the day - we were the oldest ones there! We hadn't planned very well and had on poor shoes. I had on hard soled clogs, and my husband had on Teva sandals. As has been mentioned there is a "house" built into one of the slot canyons. Someone there told us it was an old prison. 'Not sure that's true, but it makes a good story. There are handrails on part of the trail and a bridge connecting two of the large boulders. There were several families there and even the young children were able to climb on the tall rocks with the help of their parents. There are some picnic areas - one large one that is semi-covered and is right near the parking area, and at least one more small one that we saw. There was also a campfire area no far from the parking. It looked like a fun place for a group activity in the evening, but you would need good flashlights to get there. We were near a group of friendly young men, probably college age, that were jumping over a slot canyon, back and forth. Ahh youth, no fear. If you go, take a hat, some water and wear good shoes, and remember that St. George can be very warm so don't go mid day in the heat. When we were there they had two portable "johns" placed near the parking area. My husband used one and said they were pretty grim. It's a fun place to visit. You could probably spend several hours there if you like to hike. I'm sure we saw only a small part of the entire park and we spent about 45 minutes there.
