Throughout Coed Craig a Ffynnon there's a good quantity of oak interspersed with birch, rowan and some holly and hazel.

Wild bilberry or vaccinium myrtillus is found in quantity on the rocky crags, and at forest floor, as well as wildflowers throughout such as scarlet and yellow pimpernel and herb Robert; ferns and mosses such as the narrow and broad buckler fern and the aptly named Big Shaggy moss.

The quantity of birdlife here with accompanying song is fabulous, and woodpecker can be heard drilling for grubs. The wood warbler's distinctive call has been heard, and the song thrush - and there have been sightings of chiffchaff, blackbird, robin and wren.

The lake in neighbouring woodland, although only partially filled at present, would be the ultimate magnet for wildlife and birdlife of a great number of species, including attracting water loving birds such as the heron.

There are no public footpaths through Coed Craig a Ffynnon itself, but there is access to a public footpath which runs along the Afon Nant Cwm-Tawel through neighbouring woodland and there is another public footpath which runs along the outside of Craig a Ffynnon's eastern boundary.

Bird watching, quiet contemplation or gnarly climbing of some of the vertiginous slopes in this woodland should keep all the family happy.

The reservoir in the valley bottom used to provide water for Carmarthen but has been decommissioned for several years now. Throughout Cwm Tawel small brick structures can be seen, chambers for accessing the network of channels built to carry spring water to the reservoir when it was supplying Carmarthen with water, under the management of the Carmarthen Corporation Water Works in the late 19th C.

Nearby is the Dan-y-Coed Halt, the end of the line of the 4 mile stretch of the Gwili Railway, one of the last few stretches of functioning steam railway in the U.K. The 8 mile round trip takes you through four stations along the picturesque railway line which runs along the Afon Gwili through steeply wooded hillsides.
