From UMHC Hiking Guide
Cairngorm, 1244 metres (4081 ft) is one of the ten highest summits in the UK, and gives it's name to the National Park with in which it lies. It is easy to access, the ski center on the north side has a well maintained road, and a large car park. A funicular railway takes skiers up the mountain.
Routes
Probably the easiest Munro to climb since you typically start from the ski centre car park at 600m. Detailed weather and avalanche information can be found from the rangers at the ski centre.
The north side of the mountain is formed from a series of neighbouring Coires, creating a number of valleys and ridges to be explored.
The easiest route to the summit is simply to follow the ski tows up the centre of Coire Cas, however this route is unpleasantly scarred and for obvious reasons is not recommended as an ascent route during the skiing season.
The ridge of Sron an Aonaich lying to the northeast of the skiing area avoids these problems. Alternatively, Fiacaill a'Choire Chais offers a good scrambling route (though most difficulties can be avoided).
There are many climbing routes at the head of Coire an t-Sneachda, and in winter this corrie is one of Scotland’s major ice climbing areas.
Public Transport
A Frequent Bus service 34/36 from aviemore to Glenmore village. Also it is pretty easy to hitch hike back into aviemore from the main ski centre car park.
