This should be a relatively straight forward find in an interesting location. Nearby, the river Loughor's source can be observed, coming out of the limestone rocks into a small pool caused by an old dam.
The cache name is derived from the location's Welsh name Llygad Llwchwr, which translates roughly to the cache name, though in Welsh, probably a better translation could be source of the loughor.
You could either approach the cache from the nearby country road, passing some enormous shake holes along the way (there's a place to park next to the road which is often used by cavers) or alternatively, you could park up at Carreg Cennen Castle and take the longer circular route (there's another cache to find along this route too). If you decide to visit the castle, take along a good torch as it has a rather interesting cave to inspect (lamps can also be hired at the visitor centre).
Things to look out for: Look for several enormous trees that have toppled and now straddle across the river nearby. Also look for the cave entrance not far from the resurgence. Although mostly bricked up, there is a small entrance that's regularly used by local and not so local caving clubs and leads to several chambers and river passages beyond, but certainly shouldn't be attempted without experts.
If you have some extra time or are on the circular walk, head downstream about 125 metres to see a very rare geological feature. Here you will see a divergence where the river splits. This is quite common in British rivers but in almost all cases the split re-joins the main river. In this case however, the split is permanent and the two resultant rivers follow completely different routes to the sea, one being the Loughor which flows to its estuary and the other Nant Llygad Llwchwr, which feeds into the Cennen and eventually reaches the sea in the Towy river. I know of only one other example of this happening in the UK - and this has since been disrupted by land drainage.
