If she can deal with hike, the best stuff in pila is out of the park. The descent down to the floor is good… but its got nothing on the natural stuff there, especially when its dry and the sand on the aosta run is a foot deep…
For starters, head up the top lift, follow the walking path up to the top of the col, from the viewing point youll see a ridgeline down to the left as youve walked up, ride that. It forks a 3rd of the way down or so, hang left and youll end up back to aosta having ridden some amazing singletrack. Couple of awesome sections.
Assuming the couis lift is shut this is a ballache but you can pick up fire road from the park to the grimondet lift, youll go under it and see a track off to your right, follow that down. Make sure you dont take the wrong one and do the desarpa bike park trail. This is very rocky and continuous so not ideal with a busted foot though. Loads more natural riding in the area just watch you stay the right side of the mountain.
