Such a beautiful view!
The rollerslide wasn't too long, or too fast....
...but it goes under other climbing parts of the park.
Grass slide... maybe? I forgot to walk down there to read the sign.
To get there, head south towards Nagasaki past Bio Park. Once you're in Kinkai, pass the Mobile station on the right and look for the sign above on the left side and turn there. You need to turn right to keep the water at your left. Kinkai is written in plants on the right side of the road; turn left and enter the park.
