The village is residential in nature but with many outlying farms. It is noted for having two bridges: one carries the old Bethesda to Bangor railway trackbed on an attractive Victorian architecture viaduct; the other is a concrete flyover built in the 1980s carrying the A55. It is credited as the start of the A4244 road, but in reality the road lies approximately 1 kilometre (0.62 mi) south of the village. "Infryn" means turf, therefore the name of the village means literally "blue/green turf".

Mynydd Llandygái (also spelt Mynydd Llandegai, [ˌmənɨðˌɬandəˈɡai] ; from Welsh mynydd "mountain", Llandygai "Church of St Tegai") is a small, partly forested hill in Gwynedd, North Wales. It forms the start of the Glyderau ridge. It is also the name of the quarry village at the base of the hill situated at the edge of Snowdonia National Park at grid reference SH600656. The village lies at about 1,000 feet (300 m) above sea level and gets strong winds and above average rainfall. Many of the houses are spread along long roads rather than clustered around a point, giving the village a somewhat decentralised feel. However the village is distinguished by two parallel rows of semi-detached quarrymen's cottages constructed during the 19th century for workers of Penrhyn Quarry, which mined slate. The first mention of housing on the site can be found in the census of 1841. Each of the houses was provided with an area of land (approximately 1 acre) sufficient to feed the family. This arrangement is clearly visible on the map of the area. This can be contrasted with the situation in the South Wales coalfields or in the industrial Midlands where no such provision was made for the workers. Originally named Douglas Hill, the name was changed in the 1930s after the inhabitants decided that they did not want to associate with the name Douglas, namely part of the Penrhyn family surname. (See Baron Penrhyn.) Physically the village has changed little since it was originally built. The area to the south is mountainous and there are a number of slate and stone quarries in the vicinity.
