Main Entrance to Vaynol Park, including flanking approach walls,

Of rock-faced snecked rubble with freestone dressings. The tripartite main entrance is in a free Indian style, with tapered pilasters and flat pyramidal finials, and bracketed cornice, repeated on piers on the flanking walls. Segmental arch to the main carriageway, and flanking semi-circular headed pedestrian arches, all with voussoirs. Iron gates with scrollwork below the lock rail. Further 'bays' to either side, each with a semi-circular headed and iron barred aperture.

The boundary walls that adjoin at right angles, gently stepped downwards, are in a similar manner to the main entrance and form a pair of deep quadrants, each of 8 bays and more finely detailed than the main wall. Battered walls and plinth and channelled freestone pilasters, coping and finials; distinctive voussoired straight-sided oval apertures, similarly iron-barred, to each bay. On the SW side, close to the main entrance, one bay is opened between piers leading to the drive to Wern-y-Gogas.
