I was hanging out with my nephews for the holiday so we went to thunder Junction, there is no entry fee, but you'd think you were entering an amusement park. Lots of things to see and do and play with, mostly playground type things, but also some neater stuff like these splash pad water area, and the small train. Highly recommend this for the kiddos if you're in St. George or just passing by.

It's decorated for Christmas right now with a big, beautiful tree that lights up at night. I felt very calm and relaxed here. The only downside was that the park is right next to a main road, so not the safest for small children and maybe not the most quiet park. Still so beautiful.

Hidden Valley Park is easily one of the best playgrounds I have taken my toddler to in the St…read more George area! It is tucked away in the back of a neighborhood area in the southern part of town. This playground features a huge, well-maintained play structure with tons of space for running and exploring. Compared to other playgrounds, it is also well-shaded. There is also a smaller toddler play structure, although that one does get a lot more sun exposure. Beautiful grassy areas and tons of trees surround the playground. It is also next to a covered picnic table area. There is also a splash pad that we didn't get to see this time, but hopefully next time we will! I wish we could have come to this park more than once. But it was a little bit out of the way compared to the other places we visited. But it is definitely worth including on your list of St. George playgrounds!

The town square has a myriad of things including some picnic tables, art work, sculptures, and music playing through some speakers in the nearby tower. While sitting there enjoying a picnic lunch a roadrunner decided to show up and it was funny to see some little kids chasing it. The bird was probably stressed but the little kids thinking they had a chance to get close it it was making me laugh. All we needed was a coyote (meep meep). There is a carousel, a splash pad, and lots of art sculptures. The area is lit up right now in Dec, with Christmas lights, and they are done pretty well. There are plenty of shops and restaurants nearby within 1/4 - 1/2 mile, easy to walk around. Check out my photos.

There's a path that winds through the park that takes you through the trees, past the flowers and the bushes.

Even though it gets extremely hot in the summer, there's a good amount of shade, so this park can be enjoyed morning, noon and night.

Light snacks, water and protein bars were available to runners after the race, as well as tote bags.

Incidentally, I ended up taking first place in my age category and was awarded a Gold medal.

Good quality pickleball courts. Ridiculous thing about the pb here as opposed to any other park is…read morethat the courts are a whopping TWO MINUTE drive from the entrance. So deep in the back of the park, seems excessive to me. With any other park, the pb courts would be no more than a two minute WALK from the park entrance. Anyway, I visited here from out-of-state seeking a challenge, but the numerous people here were just beginners, so I couldn't get the challenge I'd sought. Friendly people, nonetheless. I played singles full-court with a nice man at least. And the park's name is an unnecessary mouthful. Could just be called Sullivan Park.

Water park areas were a bit small but still fun for the kid. They could use some lights around the pillow jump area at night but that's a small thing. Big shoutout to the reservations manager. We had booked a year and a half prior and our site we chose was moved (due to the site programming changing hands between the time we booked and the time we stayed) and after some discussion they were able to get us a site that we felt comfortable with on a very busy weekend. Note to future campers. Pay the extra fee to keep the spot you booked. Or they will move you to a crummy one. All in all we had a great time for our spring break and will recommend to friends.

The Goods *This park…read moreis super affordable and easy to book online *Animal friendly *so many kid activities like they didn't cheap out at all! *very clean loving the clean bathrooms *Staff are helpful * lines for water slides weren't bad at Al I did go during the week *clean area sights The Bads * Reduction for 1 star because it's super annoying and very upsetting the biggest problem I had was checking in. Ok remember I'm from Vegas a single mother with a 8 yr old ok. Now when you first check in you approach the park and you see the little check in booth like you see in every campsite. Theres no one in the box and the park is very modern looking so you really can't figure out where's check in?! There's no one around, no one pickups the phone and it's 4-5pm on a Wednesday. I'm trying to figure out the tent sights finally I see someone! I ask her where is the ranger check in and she points behind her what looks like a long building that a little shop. Well ok I thought where the hell is the person in the box to direct me here I'm wondering and why not a bigger sign saying ranger station checkin here in big letters? Or in the box put a picture saying go down to ranger station it will be on your right show building picture? The little box looks like an abandoned lottery ticket sales booth. Maybe have more staff walking the property I got lucky saw 1 staff member after I circled the park twice! * As always make sure you don't forget your graham crackers because with tax it was around $8! And $4 for a Hershey regular candy bar. Ice water you think be free nope it be $1.58! How is it Starbucks gives you a free water here nope it's wild because you think that would be included drinking water to stay hydrated but ok I'll pay it to fill up my Stanley thermos. * Children life vest for the pool area, ok this one another star reduction! My child is 8 skinny little boy he is. And he fits the CHILD VEST.Well it's very surprising they let you take as you please these life vest in all sizes. However the child size most popular size I imagine that's why there all messed up in the front of the vest you can't tell until your kid gets in the water. What I mean is you know how a life vest has two part in the front a chest plate in each side. Well one side of the vest right around the rib cage it's like some cut the foam in thin side horizontal so it's a piece that floats up by your kiddos face. So most children vest need to be replaced as there inside pad/lining is deteriorating and is balling up or just feels like a squishy foam. I tried putting him in a bigger size but bigger sizes will pop off because they don't got the underneath leash buckle. So lastly the hot tubs at the water zone park area there's 2 hot tubs there spacious but this is a child park these hot tubs are the hottest I mean the hottest hot tubs I ever felt and I come from Vegas where I been in so many in the casino resorts. The hot tubs are scaulding hot im just wondering hot tubs aren't the best for little children but I seen moms with 2 years in there it was such a shock. My son dipped his foot screamed it's hot! But how can they let unsupervised children in a cooking soup pot I'm wondering?! **Tent sights are nice but at night it's very bright because the bathroom lights that are right next to you. *Lastly I will say there needs to be a stop sign guard yard duty out side to monitor traffic you have giant I mean giant RVs with huge huge trucks pulling these beast and check in like I said is the building where the round about is where you got little ones on electric scooters bikes skateboards and most of them aren't accompany by a parent. These large vehicles can't see over their dash boards and I almost was ran over by a huge truck pulling a freaking house. I'm a short lady that's 4'9 ok it was very scary. But come on you have like 5 cleaners in the house keeping little box near the bathrooms twiddling their thumbs and you can't get a yard duty stop sign guard lady because these kids don't have their parents looking after them. The jump pad has no one monitoring the children as well as I see big kids doing back flips as little ones are right beneath them jumping. The jump mat says no flips but you really think kids are going to listen you got two life guards in the water park but no other reenforces around the pavement/park area ground like I said a alot of kids are not accompanied by there parents or simply don't want to parent. I won't reduce any more stars because I found it enjoyable the price for tent was good regardless of these little tid bits I know now for next time right. So I'll update it once I go back and see if they changed certain things. But I feel like my points are valid. *tip If you camping in a tent bring ear plugs as your close to your neighbors that you can hear them snore. Ask about your parking as it is confusing for the tents. Oh there's only 2 tent spots available like in the whole park.
