The spectacular waterfall in Coedydd Aber National Nature Reserve has been popular with visitors since Victorian times.

Known locally as Aber Falls, the Rhaeadr Fawr waterfall (which means "big waterfall" in Welsh) tumbles down from the Carneddau mountains and plunges into a deep basin in the river valley below.

Through the ages, climate, geology and human activity have all left their mark here and there is plenty to see on the way along the valley to the waterfall.

There are wide areas of open grassland and woodland, made up of oak, hazel and alder, which is home to many different birds.

The humidity near the waterfall and along the river makes ideal conditions for a variety of mosses, liverworts and ferns, and over a hundred species of lichen have been recorded here.

There are also many features of archaeological interest, including an Iron Age hill fort and the remains of several ancient round huts.

What to see on the National Nature Reserve

During the year, the landscape changes at Coedydd Aber National Nature Reserve.

Depending on when you visit, you are likely to see different wildlife, too.

Read on to find out what you could see here during the different seasons.

What to see in spring

The resident woodland bird population swells in the spring with the arrival of migrant breeders, such as:

  • Pied flycatchers
  • Wood warbler
  • Redstart
  • Crossbills

The ash and wych elm woodland floor has a glorious carpet of bluebells and wood anemone.

On the ffridd (the land between the valley floor and the high mountain) the hawthorn and crab-apple trees create a foam of white flowers in May.

What to see in summer

Woman on bench in summerThe alder wood is carefully managed by coppicing some of the trees in rotation which leads to a dramatic burst of meadowsweet flowers in summer.

The woodland is home to a range of birds such as the great spotted woodpecker and goshawk which feed on the ground in the broadleaved woodland and the nearby coniferous forest.

Throughout summer these bird species can also be seen:

  • Pied flycatchers
  • Wood warbler
  • Redstart
  • Crossbills

The fast flowing river provides habitat for the dipper and grey wagtail, whilst the ffridd (the land between the valley floor and the high mountain) attracts species like the tree pipit and wheatear.

Ring ouzels, ravens and flocks of choughs can sometimes be seen on the open mountain slopes and on the steep rock wall at the far end of the valley.

What to see in autumn

As the days begin to shorten, the trees get ready for winter and the valley fills with a dramatic patchwork quilt of red, orange, brown and yellow.

What to see in winter

The spectacular waterfall, which is the main attraction for many visitors to Coedydd Aber, is particularly impressive during winter.

Many of the migrant birds leave the reserve for warmer climates but overwintering species such as the dipper and grey wagtail can still be seen throughout the colder months.
