Our View

The most notable physical feature of the Coedydd Aber NNR is Rhaeadr Fawr, (‘big waterfall’), which lies is at the head of the River Aber. The humid nature of the reserve’s woodland makes it a great place for some rare ferns, mosses and lichens. An unusual plant found in significant numbers is the feathery wood horsetail, which is uncommon in North Wales. The reserve is also exceptionally good for fungi, including fly agaric, oakbug milkcap and turkey tail. Spring migrants in the Coedydd Aber woods include pied flycatchers, wood warblers, tree pipits, redstarts and wheatears, and in the nearby conifer plantation, crossbills have been seen. The great spotted woodpecker can be heard in the woods, and along the river look out for dippers and grey wagtails – you might also catch a glimpse of a kingfisher. Closer to the waterfall ring ouzels, choughs and ravens can sometimes be seen. The most notable mammal living in the reserve is a thriving population of weasels, and you might also see bank voles and wood mice.

About the area

Discover Gwynedd

The county of Gwynedd is home to most of the Snowdonia National Park – including the wettest spot in Britain, an arête running up to Snowdon’s summit that receives an average annual rainfall of 4,473mm. With its mighty peaks, rivers and strong Welsh heritage (it has the highest proportion of Welsh-speakers in all of Wales), it’s always been an extremely popular place to visit and live. The busiest part is around Snowdon; around 750,000 people climb, walk or ride the train to the summit each year.

Also in Gwynedd is the Llyn Peninsula, a remote part of Wales sticking 30 miles out into the Irish Sea. At the base of the peninsula is Porthmadog, a small town linked to Snowdonia by two steam railways – the Welsh Highland Railway and the Ffestiniog Railway. Other popular places are Criccieth, with a castle on its headland overlooking the beach, Pwllheli, and Abersoch and the St Tudwal Islands. Elsewhere, the peninsula is all about wildlife, tranquillity, and ancient sacred sites. Tre’r Ceiri hill fort is an Iron Age settlement set beside the coastal mountain of Yr Eifl, while Bardsey Island, at the tip of the peninsula, was the site of a fifth-century Celtic monastery.
