Go the the top of Groppera. The there are two variations; climb the fence and go to the top (30 m from the exit from the lift) and ski down the colouir or ski down the ppiste to skiers right and exit the pist after the fence has ended.
The is a classic alp descent starting in Madesimo and ending in the village Franscisco. Its a quite easy run but very long and offer stuning views. Its not steep unless you choose to start with the colouir. Easy to find route and easy skiing.
From Franscisco there are free buses to the lift that takes you up to Madesimo again.
