Climbing up and down

Stairs and ramps to access the higher levels of toys can be effectively replaced with raised duny areas made from grassy ground.
If the conditions allow to take advantage of the natural conformities of the area, and provisions are made for embankment to create a number of hills artificially, it would be interesting, by creating the appropriate connections, to propose this solution for reaching toys located above ground level.

These rises should have slants and be at the adequate height making it possible to access them even by crawling; they should be sufficiently levelled, at least in the area of greater transit. It would be appropriate to locate useful elements like fencing, handrail, chords or sticks to keep the control of balance, facilitate the climb back up and recognise the route. D
