Marilyn · Central Highlands
Cruban Beag
Cruban Beag — the small hump — is a 590m Marilyn in NN-square Badenoch, sitting on the moorland between Glen Truim and the upper River Spey south-west of Newtonmore. The summit gives wide views across to the Monadhliath and east into the Drumochter pass with the A9 threading along its base.

Standard route
heather moorland 65% · bog and rushes 25% · grassy summit 10%
The shortest line uses the lay-by on the A9 at the Truim viaduct, crossing the railway by the underpass and climbing the rough east shoulder onto the broad summit. An alternative route comes in from the Phones road on the west, slightly longer but easier underfoot.
Terrain
Mixed grouse moor and bog at the lower levels, with stretches of bare gravel and tundra-like crowberry on top. The Allt na Cuile must be crossed below the summit — straightforward in normal conditions.
In winter
A drier hill than its Lochaber neighbours but high enough to hold proper snow from December onward. Plateau-style navigation in cloud; spindrift in north winds turns the gentle top into a featureless white expanse.
This hill is in the Creag Meagaidh SAIS forecast area. Check SAIS forecasts in winter (December–April).
