It's small, and pretty fast. Both my 5 and 7 year olds are entertained by it; I'm not.... Especially after the 20th time around. I don't find it long enough to be lazy and if caught by the jets, I have to hang on to my 1 piece suit because those things are strong enough to jettison inner tubes and fabric. Kids love it, adults tolerate it
I cannot honestly give you exact dimensions but it takes around 2 minutes to go around. It is not large but it is indoors.
