In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Capel Curig like this:
CAPEL-CURIG, a hamlet and a chapelry in Llandegai parish, Carnarvon. The hamlet lies on the river Llugwy, at the foot of Moel-Siabod and Snowdon, 5½ miles WSW of Llanrwst r. station. It has a post office under Conway, and a hotel; and is a polling place, and a resort for tourists and anglers. Public coaches daily pass through it. The surrounding scenery is most romantic; and the route hither to the top of Snowdon, though the most toilsome, is the best. The chapelry includes the hamlet; and is a vicarage in the diocese of Bangor. Value, £89. Patron, the Bishop of Bangor. The church is very old but good.
