Our big beginner day out is up super morzine, ridge to avoriaz, ppds route to the bottom of mossette, along the valley to linderettes. Lunch there or goat village. Down the road to the bottom of the lift. Off road to lac Mondrian. Stop there for paddle/swim/ice cream. Follow the vtt route by the river to valley floor then along the floor by the river through the woods back to morzine.
Rest of the family could meet you at the lac. Its easy to get to by bus or car.
If you don’t fancy the road and lake route then back up to avoriaz from linderettes, along the ridge, down under zores and bubble down is good.
You can add a loop up mossette and down the ppds route. Nothing too sketchy on that but there are a couple of little climbs.
Panoramic is good too. The blue back from there is OK. Fairly steep fire road to finish so you need good brakes and control.
