How to do it: First of all always from the inside, so you need to get into that temporary desert through climbing over the wall or finding a gap big enough to slip through.
Use the lower part of the wooden frame for your feet and the upper part for your hands. Feel the stretch if you are small. Then move across, in between you can climb up and down again or squat and hold onto the middle bar of the frame. Half of this kind of wall takes about 20-30 min.
