This natural upland lake surrounded by
heathland and mire is a good example of clean and low-nutrient
water, lying 300m above sea level. The lake is some 10.5 hectares
in size, about 7m deep at the deepest point.
The surrounding area of upland heathland and acidic grassland is
typical of this part of mid Wales and is common land, grazed mainly
by sheep.
How to get there
Take the second left turning from the B4576, south from
Aberystwyth, as you come south through Llangwyryfon. Continue
through Trefenter until you see Llyn Eiddwen in front of you and to
the right.
There is limited off-road parking by the cattle grid at the
north east corner of the lake.
There is a public footpath along the ridge and access is only
available along the lake’s western shore; these routes are not
accessible for wheelchairs.
Public
Transport
The Royal Mail provides a limited service
(595) to Trefenter.
The 585 Aberystwyth / Lampeter bus service passes through Bronnant
– a 4-5 km walk from the lake.

water lobelia is abundant, with shoreweed, spring quillwort,
awlwort (at one of its southernmost locations in the UK) and
floating water-plantain.

Bottle sedge and water horsetail
dominate the vegetation at the south end of the lake, while cotton
grass and bog mosses predominate at the north end, with some bog
asphodel and cranberry.
Aquatic invertebrates include the keeled skimmer and the
sponge-feeding caddis fly. The threatened water vole inhabits the
shoreline, and there are populations of native brown trout, pike,
minnow and three-spined stickleback.
The lake is important locally for wintering wildfowl, including
coot, mallard, pochard, teal, and wigeon with part of the flock of
whooper swan which winter in central Ceredigion. Black-throated
diver and green-winged teal have visited the lake in recent
years.
