In some instances, after climbing up hundreds of feet of rock from the corrie below, one finds that the last twenty feet of the mountain is up a steep slope of peat, occasionally almost corniced by the overhanging fringe of heather. Then, too, the luxuriant growth of the trees in some of the valleys, especially those near Killarney and at the head of Caragh lake, is wonderful, and it is almost needless to say that the upper part of the Lake of Killarney itself, beneath the Macgillicuddy's Reeks, is unrivalled in the British Isles for rich beauty. There are larger lakes surrounded by far wilder scenery in Scotland, for instance in Glen Affric, or lakes like Loch Katrine that lie between wonderful forested shores and beneath shapely mountains, or Rydal Water or parts of Derwentwater in the Lake District; but the upper lake at Killarney, as an example of winding stretches of clear waters, with rocky shores clothed in oaks, firs, hollies, and other trees, the foliage stretching upwards to the heather-covered mountains behind, this particular part of the Kerry mountain land certainly in its own way stands alone; it has no competitor.
The warm moist Atlantic climate has had almost the effect of a hothouse on the flora of these sheltered valleys, whilst above, on the summits of the mountains the first snow and storms of the winter and early spring produce a rugged wildness that is only to be found in the British Islands on mountains over 3000 feet high.
Carran Tuohill, the highest of the Macgillicuddy's Reeks, also the highest mountain in Ireland, lies some distance away from Killarney. Its eastern and northern faces are especially grand. At its foot can be found more than one mountain tarn; Lough Gouragh, at the head of the Hag's Glen, being very fine, for the greatest mountain precipice in Ireland rises from its shores almost to the summit of Carran Tuohill, about 2300 feet above. On the other side of the mountain, another tarn, Coomloughra, is of a more ordinary type, even although it is encircled by the three highest peaks in Ireland. Notwithstanding that the face of Caher, which overlooks Coomloughra, is precipitous for more than 1000 feet, yet there is no very good climbing to be obtained on it, for the rocks are treacherous; also, they run diagonally up and across the face of the mountain.
The views from all these mountains that surround Coomloughra are very fine. That from Been Keragh perhaps is the best for the surrounding peaks; for, looking across the Hag's Glen at the black precipices of Carran Tuohill and at the savage ridge which connects it with Been Keragh, one wonders that such wild and desolate scenery can exist so near to the rich and luxuriant vegetation of the valleys only a few miles away.
From Carran Tuohill it is towards the west and south-west that the finest outlook is obtained. Across the valley in which Coomloughra lies are the cliffs of Caher; Dursey Island is seen in the distance at the mouth of the Kenmare river; the small but shapely Skellig rocks jut out of the open sea far away in the west; and Brandon, one of the most beautiful of mountains, stands alone and solitary on the shores of the wild Atlantic beyond the blue waters and the yellow sands of Dingle bay. Heather moorland, desolate loughs, and peat mosses extend for miles, and the great dome of the sky, perhaps flecked with soft clouds, bends down to the far off horizon of the outer ocean.
To the west of the Macgillicuddy's Reeks, in a part of the country but little visited, is Lough Coomacullen, one of the most wonderfully beautiful mountain tarns I have ever seen. Hidden away amongst the hills, and difficult of access, it has attracted but little attention, yet with its glacier-worn sides of bare rock that descend in many places sheer into the black waters below, and the circle of cliffs which surround the upper part of the lough, one might almost imagine one was in Norway, except that the deep velvet brown of the heather, the few well-grown hollies clinging to the broken rock walls, and the rich colours of the mosses, lichens, and ferns that find nourishment on the ledges and faces of the precipices, at once show that one is on the Atlantic coast and in a softer and warmer clime.
Five hundred feet below this small tarn lies the larger lake, Coomasaharn; it too has a shore line much wilder and more rugged than the majority of British lakes. Great boulders and masses of glacier-worn rocks surround it, whilst at its head the precipices extend almost to the summit of Coomacarrea (2542 feet). In some places these precipices give good rock scrambling, but it is rather surprising, after a couple of hours' climbing on good hard rock, to find that the top of the mountain is a flat peat moor which in some places almost overhangs the wild corrie below.
This capping of peat on several of even the wilder mountains seems to be characteristic of many of the summits on the west coast of Ireland. The highest summits of the Reeks, however, are quite free from peat.
There are, of course, many other mountainous districts besides those I have already mentioned. The Mourne mountains, where the mountaineer may, if he chooses, collect topaz and beryls of a most exquisite blue, the Wicklow, Tipperary, or Waterford groups, all possess wild mountain scenery, and many rare plants can be found there. But after all, undoubtedly it is the picturesque side of the mountain land that makes to the wanderer in Ireland the most forcible appeal of all. It is the atmospheric softness, and the rich vegetation, which, on the west of Ireland, covers the valleys, glens, and the mountain-sides, it is the colour of the deep and lovely tarns, of the expanses of heather, and of the distances, and lastly, it is the rugged, rock-bound coast, a coast of many bays, of desolate islands, of solitary sea stacks, of cliffs, of sandy beaches, and wonderful sea caves, a coast that has for ages withstood the attacks of the mighty waves of the storm-driven Atlantic; these are the beauties of which this Irish mountain land can boast, which after all are of more worth than the attractions of many inaccessible pinnacles and many ranges of ugly but excessively steep and high mountains.
