Grazing animalsCattle and sheep, early spring and late summer
The site is very wet and unfortunately isn’t accessible to visitors with limited mobility. Sphagnum takes years to recover from trampling – please avoid walking over the bog and follow the permissive path around the perimeter of the reserve. The open-access fields crossed to reach the site can contain cattle and sheep – please be respectful.
The reserve is situated 2 miles SW of Llansannan. Approaching from here, leave the B5382 for the B5384 toward Gwytherin. Take the second L, pass over one cattle grid and look for a small layby on the right (SH 911 634: if you reach the next cattle grid, you’ve gone too far). Park here, cross the road and walk up over the field on the left, head through the kissing gate and follow the old hedge bank on your L to reach the reserve.

About the reserve
Our precious peatlands
Whilst, at first glance, this reserve may present itself as a green-brown jumble without much going on, it only takes a little bit of time exploring to discover that peat bogs are amongst the country’s most diverse habitats. Peatlands provide benefits for people too: the UK’s peatlands store around 4,500 million tonnes of atmospheric carbon (that’s 100 times more than all UK vegetation, including trees) and 70% of our drinking water comes from peatland river catchments. Sadly, this habitat is threatened – once common across the UK, few peat bogs remain today, having been drained for farmland and forestry.
Blaenyweirglodd hosts six varieties of sphagnum moss along with a huge variety of specialised plants such as bog asphodel, round-leaved sundew, bogbean and common cotton-grass. This wealth of plant diversity is accompanied by huge varieties of invertebrates, with over 230 species recorded at the site. These in turn attract birds such as redstart, redpoll and linnet.
