There are several routes to the top of Moel Siabod, only one of which is marked on the local
Ordnance Survey map. 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. ;From Dolwyddelan 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. Along the dirt tracks through this land there is a fork signposted "Moel Siabod" (left) or "Capel Curig" (right). The latter path leads first of all to Pont Cyfyng, where it is possible to join the path above, or continue to Capel Curig and join the first route. The former path is a more direct route to the summit. This path continues on dirt tracks for a while before heading onto a footpath through the forest and thence onto access land. At this point, the path - which occasionally requires the use of hands to get up the rocky path - follows a stream which originates at Llyn-y-foel. ;From Capel Curig The most popular route starts from the
Plas-y-Brenin National Mountaineering Centre in
Capel Curig, and is therefore used for guided excursions. It is the gentlest of the three most common routes and is the only one marked on the OS maps. 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. ;From Pont Cyfyng A well marked turning onto a very steep tarmacked road in the village of
Pont Cyfyng (not the first turning with the pedestrian sign) marks the beginning of this route, with a footpath leaving the road after about 100 m. This footpath forks, with one route taking a sharp ascent onto the main ridge and one a more gentle route up through an abandoned
slate mine and up to
Llyn-y-foel from where there are several paths to the summit (not marked on the OS map) via the minor ridge to the east. ;Paths from Llyn-y-foel to the summit There are numerous tracks around the lake which will allow a walker to get from any point at the lake to any other without too much trouble. The main route from the lake to the summit heads to the south of the lake and then turns sharply right and ascends the minor ridge to the summit. There is a further, more obscure path that ascends very steeply over rockfalls and some
scree directly onto the ridge from the lake. ==Cultural references==
