Both resorts are at the heart of the Portes du Soleil ski area, which incorporates the skiing at 12 villages on either side of the French-Swiss border.
The skiing here is not quite fully interlinked, however, otherwise it would be more widely acknowledged as the world's biggest ski area (as it claims to be). Its 650km (407 miles) of runs total more than the Trois Vallées, which is popularly regarded as the world's biggest as all its runs are lift-linked – but who's splitting hairs?
Needless to say, with such a huge area there's a vast choice of terrain suiting accomplished skiers, intermediates and also beginners looking to take on their first few runs. The snow is reliable in both resorts, with Avoriaz offering the most snowsure slopes and Morzine having invested heavily in snowmaking – the ski season in both resorts runs from mid-December until mid-April.
The ski area between the two resorts is known as Super Morzine and offers plentiful options, but those staying in Morzine may instead opt for the ski area on Le Pleney/Les Chavannes rather than Mount Ranfolly, which is shared with another neighbour, Les Gets.
From Avoriaz, it’s easy to head over to the Swiss resorts like Champéry, with brave skiers having the option of taking the infamous Swiss Wall black run down (many others descend on the chairlift).
