Connemara Bog Complex SAC covers most of the Connemara lowlands in County Galway. It supports a range of habitats with extensive areas of blanket bog and heath. The site has areas of deep peat surrounded by rocky outcrops covered by heath vegetation. There are areas of old oak woodland where the invasive shrub rhododendron occurs. The site is nationally important for Greenland White-fronted Goose and contains nesting sites for Golden Plover.

The Twelve Bens/Garraun Complex SAC is situated in the north-west of Connemara in County Galway. This mountainous terrain includes extensive tracts of lowland blanket bog. The dominant vegetation type is upland blanket bog/heath. Near the summits this has developed on a layer of very thin peat with a high proportion of outcropping bedrock. The site contains small areas of old oak woodland, a habitat which is particularly rare in Connemara. Some woodlands are heavily infested by rhododendron.

Maumturk Mountains SAC is situated east of the Twelve Bens in County Galway. Wet heath is widespread on the lower slopes of the mountains. Dry heath is present on steep slopes. Some intact lowland blanket bog occurs within the site.

Sonnagh Bog SAC is located at the northern end of the Slieve Aughty Mountains in County Galway. The slopes are dominated by Purple Moor-grass which covers a carpet of bog mosses. Flat areas occur on the lower slopes which are devoid of this grass and dominated by Bog Asphodel. Red Grouse have been reported on the site.

Rosroe Bog SAC is situated on the largest peninsula in Bertraghboy Bay, Connemara, County Galway. The site comprises gently undulating areas of blanket bog interspersed by scattered rocky ridges, with heath. The undisturbed areas of this site have well-developed bog moss lawns. Typical blanket bog plant species occur in these areas. There is a fringe of cut-away bog along the seaward margin of the site. The bog vegetation grades into dry heath, found in the southern and western parts of the site.

Loughatorick South Bog SAC is located about 8 km north-west of Mountshannon, straddling the Clare/Galway border. It occupies the summit of Scalp Mountain, and extends down the gentle slopes to the south and to the east. Scalp is one of the southernmost, and lower, of the Slieve Aughty Mountains, reaching a height of 325 m
