Walk in from Aberarder car park to Lochan a' Choire. Ski boots/ice axe/crampons on and then an ascent followed by ski descent of Easy Gully (I) - probably the most prominent line in Coire Ardair - back to the lochain.
Had a look at Raeburn's Gully, but only got half-way up before it became obvious that a large avalanche runnel (perhaps caused by a large chunk of the icefall falling off last Thursday) had rendered the top half unskiable. Descended from there.
