Ninja Warrior Obstacle Course for Kids Backyard - 2×50ft Slackline Kit with 10 Most Complete Accessories for Boys & Girls, Swing, Rope Ladder, Gymnastic Ring, Climbing Net, Arm Trainer and Monkey Fist

This ninja obstacle course has completely transformed our frontyard into a mini adventure playground. Setup: Installation was easier than expected. As long as you have two sturdy trees, the line tightens well and stays secure. The included attachments are simple to adjust, so you can customize the layout depending on age or skill level. Build Quality: Everything feels solid and reliable—the line, straps, and attachments all hold up well under active use. Even with multiple kids climbing and swinging at the same time, it remains stable. Kid Engagement: This is where it really shines. The kids naturally rotate between the climbing net, rings, and swings, and they’ll play for hours without getting bored. It’s a great mix of fun and physical activity—balance, coordination, and strength all in one. Overall: If you’re trying to get your kids outside more and actually stay outside, this is a home run. It’s one of those rare purchases that delivers exactly what you hoped for—and then some. Last: I have 2, 4 , 6 ,8 years old kids. They all enjoyed it!!!

Fun alternative to a fixed playground structure. Slack lines were easy to install took a few times putting the clips on before we found a system that didn't hurt our hands. Kids have been playing on it nonstop since we put it up a month ago. The slack line as long as its tightened as much as it can doesn't sag too much even with an adult on it. All attachments are durable as of now and have been working as described. Would absolutely buy again and will recommend to friends.

Pretty good course for back yard. The course and parts are well made. Unfortunately our tree is too small for the course to be installed. Please be aware that the tree needs to be at least 12” inches diameter for safety. Out tree is a little smaller than that. but because of the quality, we will keep this and wait a little bit for the tree to be bigger and stronger to support the system.

Fun and versatile. The only negative is the width between the rings

Got this Ninja Warrior obstacle course as a birthday gift for my kid, and he absolutely loved it. The 2×50ft slackline is sturdy, and all the accessories—swing, rope ladder, rings, climbing net, monkey fist—give him plenty of ways to play and stay active. It basically turns the backyard into his own little obstacle gym, and it gets him running, climbing, and burning energy instead of being stuck inside. Setup was easy, everything feels solid, and he’s been on it nonstop. it’s a birthday gift that’s fun and actually gets a kid moving instead of video game.

I got this obstacle course after much research. The quality and quantity of the items included is very much worth the price, especially when fixed sets are in the thousands. It's easy to set up. Better to get everything on before the slack line is tightened around the trees. We had a few things hanging from the trees already, but this allows us to accommodate more kids. This has been a big hit with our kids, their cousins and friends all summer and now well into the school year. And yes, there are dirt patches where grass used to be. We plan to take it down when it gets too cold but for now (November) they're still playing on it.

We were interested in having a play structure in our yard for our children, but we didn't want to spend thousands of dollars nor install something permanent that would take up half the yard even after they'd outgrown it. This has been a great compromise. I like the flexibility this system provides to rearrange -- and even replace -- obstacles/play items. The first photo in the review is what it looked like when I first set it up brand new. (Our trees are not very far apart, so I wrapped a single slack line around 3 trees, making 2 sides of a triangle. It's not perfect, because the obstacles at one end can run into each other, but my kids make it work.) The second photo is how it's morphed over a year and a half of use. I've moved obstacles around based on what order works for the play my kids are doing at specific times. We took down the cargo net because it was too hard for our 2 and 4 year olds and repurposed the 4 buckles it was using with a baby swing and a disc swing. (We also added a hammock and climbing holds on the tree.) I've loved watching the kids figure this out and improve their skills, and it has held their interest for the 18 months we've owned it. My 5 year old can traverse the whole course without touching the ground now, so we'll probably have to put the cargo net back up soon. And I'm happy to have the flexibility to adapt it to their needs as they grow. The slack line and buckles have held up surprisingly well to 18 months of intense sun (and even an ice storm that knocked down tons of branches from all those trees). The wooden bars of the ladder and monkey bars still work, but they're definitely showing signs of weathering. I regret not treating them with a weather-proofer before leaving them outside for so long. And the squirrels have nibbled away all parts of the tree protectors that were peeking out from the slack line. My impression before purchasing this was that it would be relatively easy to install, and we might put it up and take it down sometimes. But it was not. It took me quite some time just to get all the buckles laced onto the slack line. Then it took me and my husband a couple hours to fully figure out getting the slack line at the right height and right tension. Definitely not a one person job as I was imagining it would be. We have not taken it down at all in the meantime, though we just recently did loosen the tension a bit to rearrange the exact spacing of the buckles. We were able to do it, but we didn't move anything more than a couple inches because they were very hard to move. Beyond installation, my only complaint is that they don't sell additional buckles. The slack line is so long it could easily accommodate several more obstacles (if you have the space between your trees), but they only send the exact number of buckles to support the obstacles that come with it. If you could get more buckles, this would be so much more extensible.

The items seem to be well made and very sturdy, however the assembly instructions are absolutely the WORST. If not for a YouTube video we would be returning this item. The instructions are worthless. In addition we only received two tree protection felts not four as shown . There are no guidelines for how high to install, and since we were installing for a 4 and 6 yr old we choose rather low, only to discover how much two very little ones could bring down the tightly ratcheted top line, making the whole set unusable at the first height installed. The photo's pictured on Amazon make it look like there are more parts than actual, as some are duplicated. There are still plenty of "stations" but buyer beware.
