Features 5
- NINJA WARRIOR OBSTACLE COURSE FOR KIDS OUTSIDE - Turn any two trees into a backyard ninja course. Two 55ft slacklines carry 10 adjustable obstacles, so kids climb, swing and balance their way across instead of sitting in front of a screen. Builds real grip strength, coordination and confidence while it just feels like playing.
- 10 OBSTACLES IN ONE BOX, NOT A STARTER SET - Includes 2x 55ft slacklines with high-grade ratchets, 2x monkey bars, 2x gymnastic rings, monkey fist, seat swing, ninja wheel, rope ladder, 12in x 12in climbing cargo net, 2x tree protectors, 17x buckle straps and a carry bag. Arrives gift-boxed, ready to give.
- RATED TO 450LB AND BACKED FOR 5 YEARS - The full line is rated to 450 lb total, so several kids can play at once. Two-inch wide, 4mm thick polyester webbing, nylon, wood and metal construction with stainless steel fasteners, anti-rust coated hardware and reinforced buckles that hold tension instead of slipping. Covered by a 5-year manufacturer warranty.
- SETS UP IN UNDER 30 MINUTES, NO TOOLS - Three steps: wrap the tree protectors, feed the ratchet, clip on the obstacles. No drilling, no hardware, no posts to sink. Needs two solid trees 15-45ft apart; the wider span lets you loop the line properly around each trunk, and the protectors mean the bark takes none of the load. Packs back into the carry bag for the park or the campsite.
- GROWS WITH THEM, AGES 5 AND UP - Slide the obstacles anywhere along the line and set the spacing to match the child, so a five-year-old and a twelve-year-old get a different course from the same kit. A birthday and Christmas gift that gets used all summer. Adult supervision recommended.

Fun for all and stable/sturdy

Great for all ages and abilities.

Great for the whole family!
Color: Purple
Size: 55ft Double Line Kit – 10 Obstacles
I purchased 2 different brands of ninja warrior courses. The trailblazer set was much easier to set up and the accessories feel and appear more study then the plastic ones that came with the other set. The straps are high quality material and feel stronger than needed. I would highly recommend this brand and this course. I enjoy that the course is able to be adjusted as the children grow and the bottom slack line can be used independently when it is no longer needed for the couse. Better investment than a traditional swing set for sure!

Super fun
Color: Purple
Size: 55ft Double Line Kit – 10 Obstacles
This ninja course has been amazing! It’s been used every single day for months and has held up incredibly well. The quality is excellent — sturdy, durable, and made to handle lots of active play. My kids never get bored and are constantly coming up with new ways to use it. It’s been great for building strength, coordination, and confidence while keeping them active and off screens. One of the best purchases we’ve made — highly recommend! 🥷⭐️

Great course, hard to install due to complicated ratchet
Color: Purple
Size: 55ft Double Line Kit – 10 Obstacles
My kids love this! It is sturdy, fits well around 2 flat trees. The installation was challenging - we could not figure out the directions on the ratchet. My 9 year son got it once by accident but we could not replicate it so we had to get another adult. We will take it down for the winter but not sure if we can get it back up in the spring! Also think about kids heights. Mine are 2.5 yrs apart (9 and 6) and we set the distance between lines to work for the younger child. It’s a bit too easy for the older one but he still likes it.

Size: 55ft Double Line Kit – 10 Obstacles
We purchased two of these for our nieces/nephews. It is better quality than i expected. Very heavy duty. I do think it'll be a little less easy to move than expected, but it will be much loved by the kids.

Great gift!!
Color: Purple
Size: 55ft Double Line Kit – 10 Obstacles
Bought for my granddaughter, much easier than a swing set and she loves it!! Was easy for two people to put up. Took a little more strength than we had to tighten the ratchet but a young dad can do it ( or mom)!!!
