All in all I built a great backyard monkey bar set for around $100. This could be more or less depending on what you have lying around. If I had built this when Mrs. C. and I first moved in I would have only had to spend around $30. The guy who used to own the house left a decent sized wood pile behind the house. We have since used all of it, or given it away. The kids love the monkey bars and it is a good fit for both my 6 year old and 12 year old. I can use these monkey bars just fine, so I know they won’t outgrow it. The set is safe, but it does move a bit when in use by a larger person, so at some point I may re-enforce it a bit to minimize the movement. Not bad for a $100 investment, and you can easily get everything from your local hardware store with the exception of the actual monkey bar rungs from Amazon.
