31 of the 71 parks we track publish a minimum height, and 19publish a minimum age. Here's what those numbers actually look like, and why the limits exist.
A minimum height requirement is almost always about the lift, not the tubing lane itself. 10 of the 15 tow-rope or handle-tow parks we track publish a minimum height or age, against 9 magic-carpet parks with no minimum at all. A rider needs enough grip strength and balance to hold a moving handle tow for the ride uphill; a magic carpet only requires the ability to sit or stand steadily, which is why parks using one are far more likely to welcome younger children with no published minimum.
Age is a rougher proxy for the same thing — two four-year-olds can differ by six inches in height — which is probably why more parks in our data publish a height minimum than an age minimum.
Among the 31 parks that publish a minimum height, the typical figure is42 inches, with published minimums ranging from 32 to 44 inches. 30 of the 71 parks we track (42%) publish no minimum height or age at all — usually the magic-carpet or walk-up hills rather than the tow-rope ones.

Policies vary and we don't have reliable data on this across every park, so this is worth an actual phone call rather than a guess: some parks allow a child under the height minimum to ride on an adult's lap, some don't allow it at all, and a few operate a separate, gentler lane for younger children with its own (lower) minimum. Don't assume either way — call the specific park before you drive out with a child close to the published limit.
