The Brévent ski station is the closest to the centre of Chamonix. The hill from Chamonix centre to the bottom station is deceptively steep to walk up, especially in ski boots. The easiest way up is to catch the free bus. Also, there is parking for up to 250 cars.
There is only 1 green run up there, so the area is a little limited for complete beginners and is more orientated towards intermediate and advance skiers. At the other extreme, advanced skiers will find the Charles Bozon run from Brévent to Plan Praz very challenging.
