Hafod Garregog National Nature Reserve, Near Porthmadog, North Wales
A tributary of the River Glaslyn runs
through the Reserve
Designations: part of Coedydd Dyffryn Nantmor SSSI
This NNR is difficult to visit due to a complete lack of available car parking apart from a small layby on the left-hand side of the road (if travelling towards Beddgelert) situated a short distance beyond the access point to the reserve; the layby can accommodate two small cars at most.
The new Welsh Highland Railway is being developed and runs very close to the NNR, but it remains to be seen if there will be a stop on the route that would make a visit to Hafod Garregog feasible by using the train.
If you are able to get to Hafod Garregog there is a pleasant stroll along a wooded lane that runs beside the River Glaslyn. THe lane also serves a few private houses.
There are plenty of lovely woodland plants to enjoy in spring, and this is an excellent place for seeing summer migrant birds.
On the return walk, the mountain views are wonderful, with Snowdon itself clearly visible when the weather is fine.
The reserve is owned by the National Trust and managed in association with the Countryside Council for Wales (CCW).

Description of Site
The woodland at Hafod Garregog is a typical Sessile Oak wood of which there are many to be found in rocky river gorges in this part of Wales.
Bluebells woods are one of the great
sites of the Welsh countryside
The rivers running through the gorges make the air very humid, and the humidity is prevented from evaporating, even in hot weather, by the dense tree canopies of the woodlands. This creates an ideal environment for mosses, ferns, liverworts and lichens in particular, and Hafod Garregog is well known for its diversity in these kinds of plants.
The spring flora, including the carpets of Bluebells are delightful, and other plants to look out for which are typical of this habitat are Common Cow-wheat, Lady's-mantle (Alchemilla vulgaris), Water Avens (Geum rivale) and Sweet Vernal Grass.
Insects thrive in the moist enviroment found in woodlands like Haford Garregog which makes it a good place to see summer migrant birds which can find plenty of food to feed their young. We are lucky in Wales to have so much ideal breeding habitat for these birds whose numbers are falling year on year due to the many perils they meet on their journeys from Africa and other far-distant countries where they spend the winter. Migrant breeding birds that arrive and swell the resident bird population at Hafod Garregog include Pied Flycatchers (Ficedula hypoleuca), Wood Warblers (Phylloscopus sibilatrix), Tree Pipits (Anthus trivialis) and Redstarts (Phoenicurus phoenicurus).
