dont miss the turn on to the D12, you do not want to be IN TlB.

Chance to tranverse to the D26 via Orcier and Lyaud or go over the Col de Feu (only recommended in good weather dry road conditions)

Up we go again

again, dont miss the turn

Option to go via Les Gets or Samoens. Morzine pretty dead outside the ski season.
Or head up the switchbacks into Avoriaz. Do that only after a few good rains in the Spring. Lots of winter gravel otherwise.

Stop for a coffe, you've earned it.

The Col de la Colombiere still closed. So bypass Cluses on the south, same for Bonneville.

In the summer head up to the Col de la Glieres. Last bit of road is unpaved but you get a mountain lodge with typical Savoyard food.

D4 junction. In the summer can go over the Colombier. Grand Bornand quite busy at all times of the year, many decent terraces to soak up the sun and lunch. If it is not sunny, you should not be here.

The long way home via La Clusaz and the Cold des Arvis on teh D909, but this early in the season opt for the westerly route to Thones.

The road layout is a mess.

You can take the D1201, but the D15 is by far the more interesting option

Reentering Switzerland.
