Complete lines
A ninja line obstacle course for kids, between two trees
A line is two straps, two ratchets and a row of things to hang from. Pick the length that fits the gap in your yard and the number of stations you want swinging on it.
The 14-Station Line, 2x65 ft
Our long run: two 65-foot straps and fourteen places to hang, swing or haul yourself up.
The 10-Station Line, 2x56 ft
Ten obstacles on two 56-foot straps — the kit most yards actually have room for.
Choosing a ninja line obstacle course for kids
A ninja line obstacle course for kids comes down to two numbers: how long the line is, and how many obstacles ride on it. Our 56-foot kit carries ten stations and suits an ordinary garden; the 65-foot kit carries fourteen and adds a swing seat and a tree swing for children who are not yet ready to cross hand over hand.
What both kits share
The same ratchets, the same fast-setup buckles, the same 880 lb steel. Obstacles slide freely, so you can set an easy run for younger ages and move the pieces further away from each other as arms get stronger. The whole course comes down easily at the end of the season and packs within the bag it arrived in, which is the habit that makes webbing last. Kids love it most in the first week outside; the point of a line you can rearrange is that they return to it in the fifth.
Pick by the gap, not by the piece count
Everything a kid needs comes within reach when the stations sit close together, and the same kit spreads out easily once they have the arms for it. Ours goes up outside in about ten minutes, comes away from the trees in five, and ages well in a dry garage. We would rather a child loves one short run and returns to it all summer than looks at a long one once.
