The most noted peaks of this mountain are distinguished by the names Moel-y-Wydva, y-Glyder, Karmedh Dhavidh, and Karmedh Llewelyn.—These hills are, in a manner, heaped on one another, near the summit; and we only climbed one rock, to see three or four more; between each is a _cwm_, or valley, generally with a lake. We made particular enquiries concerning y-Glyder-Bach, and found that the description of it is by no means exaggerated. Several columnar stones, of enormous size, formed into the most fantastical shapes, and lying in several directions, with many of their tops crowned with stones, placed horizontally on them. One we observed rocked with the slightest touch. In the fissures of the rock, _cubic pyritæ_, are not uncommonly found; the _saxifraga nivalis_, and the species called by Linnæus _æthereal_, in great abundance. The first two miles of our descent, we by no means found difficult, but wishing to take a minute survey of the picturesque pass of Llanberris, we changed the route generally prescribed to strangers, and descended a rugged and almost perpendicular path, in opposition to the proposals of our guide, who strenuously endeavoured to dissuade us from the attempt, alleging the difficulty of the steep, and relating a melancholy story of a gentleman, who many years back had broken his leg. This had no effect. We determined to proceed; and the vale of Llanberris amply rewarded us for the trouble. It is bounded by the steep precipices of Snowdon, and two large lakes, communicating by a river. It was formerly a large forest, but the woods are now entirely cut down. We here dismissed our Cambrian mountaineer, and easily found our way to Dolbadern (pronounced _Dolbathern_) Castle, situated between the two lakes, and now reduced to one circular tower, thirty feet in diameter, with the foundations of the exterior buildings completely in ruins; in this, Owen Gough, brother to Llewellin, last prince, was confined in prison. From hence a rugged horse-path brought us to the Caernarvon turnpike-road, about six miles distant; the high towers of the castle, the very crown and paragon of the landscape, at last pointed out the situation of CAERNARVON; and having crossed a handsome modern stone-bridge, thrown over the river Rhydol, and built by “Harry Parry, the modern Inigo, _Anno Domini_ 1791,” we soon entered this ancient town, very much fatigued with our long excursion. The Hotel, newly built by Lord Uxbridge, for the convenience of strangers, at the end of the town, commands a fine prospect of the Strait of Menai. The view was bounded by the flat Isle of Anglesea; while the light vessels, skimming before the wind, gave the whole a lively and pleasing variety. The city of Caernarvon, beautifully situated, and regularly built, is in the form of a square, enclosed on three sides, with thick stone walls; and on the south side, defended by the castle;—the old town-hall is now falling to ruin.
