It's summer and water fun is a necessity. That's where a new waterpark in Grapevine comes into play.

Altitude H20 is open on Grapevine Lake. That's right, on the lake. It is an inflatable, floating obstacle course on top of the water.

There's climbing areas, slides, jump off points and more.

And it's not a big cost to you according to khou.com. It's $5 to park at Meadowmere Park, where the floating course is located, and $20 for a one hour session.

There is a training course that has to be taken before hand and life vests must be worn. Lifeguards are also on duty.
