Towy is here a great, clear, rapid stream, and so it continues for the remaining thirty miles of its career. Famous view-points on it are the bridges of Llandovery, Llangadock, and Llandilo, the bridges themselves as graceful as the valley. Llandilo stands on a knoll on the west bank of the river, and rejoices in its superiority to Llandovery as a market-town. This, to the stranger, is much less commendatory than its nearness to one of the most beautiful seats in South Wales, Dynevor, where the Barons of that title have long held sway. The ruins of the old Dynevor Castle, on a hill crowded with oak, ash, and beech trees, are from the river quite ideally picturesque. It is a pity that the "common herd" of tourists have so misbehaved themselves that Lord Dynevor has felt compelled to deny free access to so charming a spot. Golden Grove, an estate as winsome as its name, on the other bank of the Towy, opposite Dynevor, has had its attractions sung by Dyer, the poet, who was born in the neighbourhood, and died rector of Coningsby, in Lincolnshire, in 1757: here is the Grongar Hill, where "often, by the murm'ring rill," one "hears the thrush while all is still."
Between Llandilo (Llan-Teilo: the Church of St. Teilo, who died Bishop of Llandaff, in /A.D./ 540) and Carmarthen, Towy's zigzags are many and eccentric. After Dynevor another castle, that of Dryslwyn, is soon passed. It is a mere ruin on a green hill. The Nelson Monument, high in the distance, on the south side of the river, is a more assertive feature in the landscape, though less welcome. Midway towards Carmarthen, we cross the Cothi, the longest of all Towy's affluents, and here, near its mouth, as great a stream as the Towy at Llandovery. Looking up it, there is even here some suggestion of its fine upper gorges. At Abergorlech, some ten miles nearer its sources, either artist or angler would find reason to rejoice in it, while higher still it absorbs streamlets right and left as greedily as the Towy itself.
One must, however, resist the temptation to loiter on Cothi's bridge by Llanegwad. There is nothing of especial mark to see by the way, save Merlin's grotto, where the Arthurian wizard fell a victim to the wiles of the fairy Viviana, and where he is still imprisoned, and will be for all time. But you must carry a fine faith with you to be fitly moved by the legend, and it will not be inexcusable if you fail to find it.
