The term 'esgair' is very commonly applied to long straight projections from higher mountains. Instances of its use are E. Weddar, E. Yn-Eira, E. Geiliog, E. Hir, and E. Galed.
Tryfaen (3,010 ft.), not to be confounded with the hill of the same name on the Llanberis side of Snowdon, or the other near Bettws Garmon, is the most remarkable rock mountain in Wales; it has two pillar stones on its summit, from which it is often said that the name (= 'three rocks') is derived. In answer to this it is enough to point out that the assumed third stone is not there, and could not have disappeared without a trace, while the name would equally well mean 'three peaks,' which the mountain certainly has when viewed from either east or west. The Welsh dictionaries give a word 'tryfan' with the sense of 'anything spotted through,' and, whether or not this has anything to do with the origin of the name, the component rocks certainly are quartz-speckled in a most extraordinary manner. The mountain is practically a ridge of rock running in a southerly direction from the head of Llyn Ogwen towards Glyder Fach, from which it is separated by a sharp dip, Bwlch Tryfaen. This dip, which may be reached either from Cwm Bochllwyd on the west or from Cwm Tryfaen on the east, offers by far the easiest ascent of the mountain. The best starting-point for Tryfaen is Ogwen Cottage, at Benglog, from which Llynbochllwyd is reached in 25 and the said dip in 45 minutes; so that, if need were, the whole height (2,000 ft.) and distance (1½ mile) to the summit could be attained within the hour. From Capel Curig, on the other hand, there is a good hour's walking before the highroad is left, beyond Gallt y Gogof, which Borrow calls Allt y Gôg (Cuckoo Cliff), and even then the traveller has about as far to go as if he were starting from Benglog. Most of the Tryfaen climbs being on the east side they can be reached from Capel Curig with much less exertion than from Penygwrhyd, the route from which involves a long, rugged ascent, hot after the sun has risen and ankle-breaking after it has set.
Climbs.—These are extraordinarily abundant, and the hold is nearly everywhere gritty and good. The most popular climbs are:
1. The east side, including especially the two gullies on either side of the summit known as the North and South Gullies.
2. The north ridge up from the head of Llyn Ogwen.
3. The west side.
The South Gully, climbed by R. W. (1887). The first ascent noticed in the Book of Penygwrhyd being that of H. G. G. and W. in 1890. On September 5, 1891, H. G. G. and E. B. T. offered some clear notes on the subject, to the following effect: The first difficulty consists of three or four jammed stones, each slightly overhanging the one beneath, with a total height of about 10 ft. It can be passed by keeping to the right close to the obstacle, but would not be easy in wet weather for any climber single-handed. At the place where the gully divides the left-hand or nearer division is not difficult. The broad division was found impracticable by a party of four on September 4, 1891, the large smooth rocks at the top being very wet. This place was climbed in 1890 by Messrs. G. and W. by keeping to the extreme right close to the wall of the gully, and then returning along a narrow ledge. It was an awkward place. There is nothing above where the two gullies unite that offers any real difficulty.
The North Gully is the more difficult of the two if the immediate centre is to be followed; but it is always practicable to break out on the face to the right. The difficulties of the South Gully are not so severe, but such as they are they must be climbed, as there is no lateral escape.
