Children over 90cm tall are welcome! "Forest Adventure" Net Course is a delight for children.
Hello. I'm Yuri and I love going out with my kids.
We'd like to introduce you to our family's favorite activity spot in Yoshinogari Town, Kanzaki District, Saga Prefecture!
Fun for the whole family! An outdoor park in the forest, "Adventure Valley SAGA" (Yoshinogari Town, Saga Prefecture)
About an hour's drive from Fukuoka city and about eight minutes from the Higashi-Sefuri Interchange on the Nagasaki Expressway, is the largest outdoor park in western Japan, "Adventure Valley SAGA."

This is a complex leisure facility where you can enjoy "Forest Adventure Yoshinogari," where you can experience treetop activities, "Trail Adventure Yoshinogari," where you can ride through the forest on mountain bikes and other equipment, and the "Zip Trip Course," where you can slide down from mountain to mountain for a maximum distance of approximately 270 meters.
The concept is "children for adults, adults for children." The whole family can have fun moving their bodies to their heart's content in the great outdoors.
Forest Adventure Yoshinogari: Enjoy four courses with varying levels of difficulty
This time we will introduce "Forest Adventure Yoshinogari."
Special courses are laid out throughout the forest, and visitors can cross from one platform, built on treetops several meters above their heads, to the next platform, and finally slide down on a zip slide, or enjoy an aerial stroll or swim in the air.

There are four courses available: the "Adventure Course" (Standard Plan 4,000 yen, Excite Plan 5,800 yen) for those in the fourth grade of elementary school or taller than 140cm; the "Canopy Course" (3,000 yen) for those 110cm and taller; the "Kids Course" (45 minutes, 1,700 yen) for those 90cm and taller; and the new "Net Course" (60 minutes, 2,000 yen), which was launched on July 5, 2025.
We tried the "Net Course" (60 minutes, 2,000 yen) with our 8-year-old and 6-year-old daughters.
Please wear sneakers. Sandals and Crocs are not allowed. You can rent a pair for 500 yen, but don't forget to bring socks.
Please note that payment is only accepted in cash.
Only 5 locations nationwide! "Net Course" available for those over 90cm tall
The "Net Course" is 8 meters above the ground and is surrounded by a strong net stretched in all directions. Unlike other courses, you can experience treetop climbing without a harness!

It can be used by anyone over 90cm tall, so even small children are welcome! They can jump and bounce on the net like on a trampoline, and play freely in the treetops.
This course is available in only five locations across the country, but in Fukuoka Prefecture, you can also enjoy it at Forest Adventure Aburayama Fukuoka.

The thing the kids were most fascinated by was the big ball pool filled with lots of colorful balls. They had a blast throwing the balls at each other and diving into them with their whole bodies.
At first, my daughters were nervous because of the rocking, but once they got used to it, they seemed to have a lot of fun. Gradually, they started to enjoy the thrill.
Children will be delighted as they can play using their whole body!
It's in a forest full of greenery, so the air is fresh and feels good ♪ The sky feels close.
Elementary school students and above do not need parental participation, but we encourage adults to return to their childhood and join in the fun!

The adults ended up with some serious muscle pain (lol), but the whole family had a great time.

After working up a sweat, cool down with some ice cream (200 yen) sold outside the front desk!

The whole family enjoyed it and had a wonderful holiday.
Reservations are accepted online. It's still hot, so be sure to stay hydrated and give it a try. (Text by Yuri-chan)
