One of my kids favorite activities in all of the Denver Metro area!! We go everytime we are in town. The best part is I can participate with them! Its up to 300lbs I believe. Wonderful friendly staff snacks and drinks arcada games basketball court and a photo booth. They also do adult only nights which sounds pretty fun! Highly recommend checking this place out. There are groupons available for parents on a budget! And they do parties 🥳 🎉

This place is an accident waiting to happen. No staff supervision in the 5n under area causing for older kids to push around the little ones. Extremely unsafe. Head first sliding is ridiculous. Talk about injury.

Way over capacity and continue to let people in, not enough mats when we were told every person should have one. All the bins are empty. No refunds.

We visited Slick City with a group of 12 and had a great experience overall. There was no wait to get in, though everyone was required to sign a waiver and purchase socks with grippy bottoms. Shoes are not allowed on the slides, so plan for that ahead of time.
We chose the 90-minute pass, which was the perfect amount of time. Two hours would have been too long, as 90 minutes was more than enough to enjoy everything without feeling rushed or exhausted.
There was a wide variety of slides that were fun and appropriate for all ages—from the youngest at 6 years old all the way up to the dads. It was great family-friendly fun and a solid option for group outings, parties, or family get-togethers, especially over the holidays.
One thing to note: food on-site can get expensive quickly for a large group, so I wouldn’t recommend planning to eat much there. Also, bring your own water if possible—there’s no free water available, only bottled water for purchase.
Non-participants are welcome to watch at no charge, and there’s a large seating area with tables to wait comfortably. However, non-sliders are also required to sign waivers, so it’s best to be prepared for that as well.
Overall, I would definitely recommend Slick City for an active, fun family event.

My teen daughter and her friend went here to celebrate her birthday. She ended up getting pink eye from the uncleaned mat she used. There was pee all over the slides and mats and there was no one there to sanitize the mats when they were taken back to the bins. The kids just threw them in the bin and the next kid grabbed them up. The toilets didnt flush and it wasn't cause they were clogged but because the flusher didnt work. The amount of trash and bodily fluids in the bathroom made me want to puke. I noticed a lot of adults did not have the spectator armbands they required me to wear and I am wondering how many people were there that should not have been. As places like this are key places for predators, I'd expect a bit more security, at least make all the adults spectating to wear a bracelet.
