Time to time, I go to the clibming gym with my daughters.
It takes 15 minutes from my home by a car.
The gym has a rule that children who are less than elementary schoolchild cannot climb there.
Whatever my elder daughter does, my younger daughter also wants to do it basically. My younger daughter is a kindergarten student now. So I hope the gym lower age limit than now.
There were less number of people there, because it was comfortable to climb outside then.
