Moel Siabod (Welsh for 'bare hill' with unknown meaning of 'Siabod') is a mountain in Snowdonia, Wales, which sits isolated above the village of Dolwyddelan.

The mountain is easily accessible from the north via Capel Curig and nearby Pont Cyfyng (by separate paths) and from the south via Dolwyddelan.

The highest part of the mountain forms a relatively level, rocky ridge approximately 800 m long, running roughly south-west (from the summit) to north-east.

All of the paths below, excluding the route from Llyn-y-foel directly onto the minor ridge, are marked on the 'Snowdonia Snowdon and the Moelwynion' Harvey SuperWalker map.

A large part of the horizontal distance covered on this route is on Forestry Commission land to the north of Dolwyddelan and the south of the mountain.

Leaving the centre, the route crosses the Nant Gwryd via the ancient bridge "Pont-y-Bala"; it almost immediately enters Forestry Commission land and follows a variety of dirt tracks and footpaths before exiting onto open access land and continuing south up the grassy northern side of the mountain.
