Sky Zone Trampoline Park 9925 Grant Street, Thornton, CO 80229

"Birthday parties pretty pricey for just two hours and ten jumpers . But as of all of us know, birthday parties can be stressful and these people that work here will do everything for you from serving the pizza, decorating and announcing that it’s time to go to the party room for bday song, cake etc. and after that they cut the kids wrist bands off so technically only one hour of jump time and other hour is what I listed above."

"First time bringing the kids here, and I don't plan on bringing them again. For $26, place is filthy, and you can tell they hardly clean the place, slide is closed and another spot. Not a place suitable for 4 and under. Guy always whistling to the kids who are just climbing the end of the trampolines to slide from the top, since the slides are close. He also stopped my kids from playing with each other.! I'd take the drive to Lava Island in Aurora for half the price,cleaner place and friendlier staff!-"

"The park was filthy. Staff standing around having social time leaving 1 person to check in 3 lines. My kids had fun but this place needs to get some control of the employees doing thier job or its gonna go down hill and possibly go out of business."

"This place is fun for the kids but VERY dirty. Bathrooms are always gross. There was even feces on the floor. The couches are ripped and the seating in the loft are weird back to back couches."

"Update: This place is transitioning from Defy to Sky zone. There is an expected layout change along with a redesign. Live your ninja warrior fantasies out here. I brought my 6 year old son and had a blast. Gigantic space, nice staff. If you don't like to bounce or jump this isn't the place for you. Kids play is during the day so don't expect to not get trampled in the evening."
