The Cairngorm Mountain company has re-started its guided walks service from the top station on the funicular railway to the summit of the mountain.
From today (May 20th) it is possible to book a guided walk to the 4,084 ft summit, which is run three times a day - 10:20, 11:00 and 14:00 BST.
Those enjoying this may be wise to put on walking boots
as they ascend from the 3,600 ft station, from which walking access to the mountaintop was forbidden from the time of its opening nearly a decade ago until last year.
A mountain that gives its name to the whole national park in the same way as its fellow railway-bearing peak Snowdon, Cairn Gorm is one of five Munros over 4,000 ft in the area.
Walkers can cross a plateau consisting of sub-arctic tundra from Cairn Gorm to the highest peak in the range and the second loftiest summit in Britain, the 4,295 ft Ben Macdui.
