Activities

Spider Man

Here’s your chance to be Spiderman! Climb the facade of the building. How about only using the window panes?

Trembling Towers

How high can you climb on the trembling towers? Can you climb the towers with no hands? or your eyes closed?

Drop Slide

The ultimate adrenaline rush — no Sender City visit would be complete without a giant human slide! This is a bonus challenge.

Toddler Park

For small ones under 40lbs! Your little ones are going to love building blocks and learning the ABCs on the traverse wall!

Fun Walls

These are the kids’ favorite walls – climb the building ladders, ascend funtopia letters, or try to balance on spinning gears.

Jump Catch

Challenge your fear of heights on the jump catch tower.  Catch the trapeze bar or punch bag.  How far out can you go? This is a bonus challenge.

Box Builder

Stack as many blocks as possible and stand on top.  Lose your balance and you’ll have to start all over again!

Mineshaft

Climb in the dark!

WHAT PEOPLE ARE SAYING ABOUT US

What I LOVE about our experience at Funtopia, was that my children were able to try something new and conquer some of their fears of heights. You would never guess that they were afraid to climb up the walls when they first arrived. By the end of their session, they were climbing all the way to the top of the obstacles.  I was not only amazed, but proud of my boys for accomplishing this feat.

I just wanted to go again and again.  We explored the entire area which included cool pillars to climb, various climbing walls, even a structure with a high platform on top in which you can jump off to a trapeze swing or a swinging punching bag thing.  It was one of those experiences I will always remember and Emma loved every minute. It was really cool to get to do something like this with her.
