An athletic facility located in the "Hirugano Kogen" leisure and outdoor park at an altitude of 1000m. You can experience tree trekking at a height of 8m above the ground where people are most likely to feel fear. Participation is possible from the third grade of elementary school and above, height of 110cm or more, and there are 13 kinds of activities in the course, including a bridge, a tightrope, a climbing wall, and a zip line, and you can enjoy an aerial walk for about 40-50 minutes. For small children and those who are not good at high places, a huge maze adjacent to them is recommended. This is the largest maze in the prefecture, an attraction aiming for the goal while pressing a stamp in the four yagura in the maze. Try to use your head and body to escape from the maze surrounded by walls so high that even adults can hide.
