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

We originally decided to create a space for our kids to release their energy after school, and that decision led to one of the best upgrades we’ve ever made to our home. We cleared out the trees on the hill behind our house, leveled the area, and laid down fresh grass to turn it into a safe and open play zone. Once that was done, we installed this ninja obstacle course—and honestly, it did not disappoint. Before purchasing, we spent quite a bit of time reading reviews and watching videos, trying to figure out which option would actually hold up and be worth the investment. This one kept coming up again and again, and now I understand why. The quality is immediately noticeable. The materials feel strong and durable, and once installed, the entire setup feels stable and secure. It’s not one of those flimsy backyard toys—it’s something that truly feels built to last. Installation was also much easier than expected. The setup process is straightforward, and the adjustable design makes a huge difference. There are no fixed obstacle positions, so we were able to customize everything based on our kids’ age and ability. At first, we spaced the obstacles closer together to make it easier. As they got more confident, we gradually increased the distance and rearranged the course to make it more challenging. That flexibility is one of the biggest strengths of this product—it grows with your kids. What I really appreciate is how it encourages outdoor play in a natural way. Instead of being glued to screens after school, the kids now run straight outside. They treat it like their own ninja training course, climbing, swinging, and challenging themselves every day. It’s not just fun—it’s also helping them build strength, balance, and confidence without them even realizing it. Watching them improve over time has been incredibly rewarding. Another thing worth mentioning is that this isn’t just for kids. Adults can use it too. The weight capacity is impressive, and everything feels solid enough that even I’ve tried it a few times. It turns into a fun family activity rather than just something to keep the kids busy. The kit itself is very complete. It comes with multiple obstacles like monkey bars, gym rings, rope ladders, and more, along with all the hooks and straps needed. You don’t feel like you’re missing anything or needing to buy extra parts. The included tree protectors are also a thoughtful addition, especially since we installed ours between trees—we want to protect them while still making full use of the space. That said, one thing I take seriously is the safety guidance. Before each use, we make sure everything is assembled correctly and check that all parts are in good condition. It only takes a few minutes but gives peace of mind. We also make sure not to leave it exposed to harsh weather for too long, and we store it properly when needed. If you treat it well, it’s clear this setup will last a long time. Overall, this has been a fantastic investment for our family. It transformed our backyard into an active, engaging environment and gave our kids a healthy outlet for their energy. If you’re thinking about creating a fun and functional outdoor space, this is absolutely something worth considering.

I bought this for my kids for Easter and it has been a huge hit. It’s been set up for about 8 days now and they’ve been using it at least 2 hours a day. It’s usually the first thing they ask to do in the morning, sometimes before even saying good morning. The setup was straightforward overall. If you’re familiar with truck ratchet straps, this will be very easy to figure out. The only part I struggled with was adjusting the connecting buckles at first because I didn’t realize the slackline needed to stay loose during that step. We set the top line at about 6 feet high, which has worked really well for my 8 and 6 year old. My kids each weigh between 85-95 pounds and are both able to comfortably play on the slackline and attachments. Our trees are about 15 feet apart, and we were able to fit quite a few attachments at once, including the climbing net, two swings, a monkey bar, and the rings. I like that you can switch things around pretty easily. We originally had the lower slackline set up, but ended up taking it down because it interfered with using the swing. We’ve put it back up a couple of times though, and it’s quick enough to adjust if you want to change things around instead of keeping it set up one way. For my family specifically I don’t know if the bottom slackline is worth it though. I think if I were to buy another slackline course for their grandma’s house I would just do a price comparison with other courses that only have one line. We keep some of the extra attachments in the shed and rotate them in, which helps keep it interesting for the kids. Overall, this has been a great outdoor activity and gets used every single day. If you have kids, this is a really fun way to keep them active outside and burn off energy. Pros: Kids use it daily. Flexible setup with multiple attachments. East to adjust and reconfigure. Works well with trees about 15 ft apart. Cons: Buckle adjustments can be confusing at first if you don’t realize the line needs to be loose.

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

The quality is excellent and it’s very sturdy. There are no burrs or rough edges. When I first opened it, there was no chemical smell at all. The installation guide is very detailed, and the buckles make it super convenient and quick to set up. It has great weight capacity—even as an adult, I can get on it with no problem

We love this slack line! The kids and their friends use it all the time! It is easy to set up but does take two people. We did not use all of the toys that came with it. We found it easiest to put the stabilizing hooks on prior to pulling it tight. Then adding the items as needed. It holds up to adults too! We found if it is stretched, it’s best if the bottom is about 2 feet off the ground or it will hit the ground by the time one person is in the middle.

Really happy with this obstacle course kit—sturdy, well-made, and comes with plenty of fun accessories. I don’t have trees, so I installed it on our backyard shade structure, which actually works great and keeps my child out of the sun. My child loves it and plays on it almost every day. A great way to stay active and have fun!

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.

This ninja obstacle course has been such a hit in our house. It’s designed for outdoor use, but we’ve actually set it up indoors using several secure hooks in our front room. We rotate the different pieces — swing, ladder, hanging bars — so it always feels new and exciting for our toddlers. They absolutely love it. It gives them a safe way to climb, swing, and burn off energy, especially when the weather keeps us inside. Any kids who come over don’t want to leave once they see it. It’s become the highlight of playdates. Overall, this has been such a fun and versatile addition to our home. Great quality and endless entertainment.

Hours of fun for kids in different age group! I bought it to donate it to our school and all kids loves it so much! It is quite simple to mount, can be mounted between two trees. Thera are ropes, ladder, swing and much much more Everything is very good quality, definatelly not cheap made!!

Glad to see these are available as hardware independent of buying a slackline with a dozen obstacles.

I don't regret the purchase it's fun and surprisingly good quality

Easy to put up and assemble. Need to cater for taller kids, so ensure you mount it high enough. Quality for the material seems to be high quality.

So easy to set up. Durable! The swing feels useless for littles as we couldn't space the top and too far away from each other because teh kids wouldn't be able to reach. Which means when they swing their legs hit the bottom line. I would buy again though. Great for the camper too!
