STRATHPEFFER, a village and spa of the county of Ross and Cromarty, Scotland, 5 m. W. of Dingwall by a branch of the Highland railway. Pop. (1901), 354. It lies in a valley of varying elevation (200 to 400 ft. above the sea), but is sheltered on the west and north and has a comparatively dry and warm climate. There are several sulfurous springs—one saline, another strongly impregnated with sulphuretted hydrogen—in great repute for gout, rheumatism, skin diseases and affections of the liver and kidneys. The well of effervescent chalybeate water is largely resorted to for anaemia and as a tonic. A peat bath, similar to those at Franzensbad in Bohemia, has also been established. The season runs from May to October, and during the past few years Strathpeffer has become a very popular resort. The pump-room (1829) and pavilion (1881) are situated in the middle of the village. Castle Leod (pron. Loud), a seat of the countess of Cromartie, upon whose property Strathpeffer is built, lies a mile to the north and is an example of the Scots Baronial style dating from 1660. The village was the scene of the fight between the Mackenzies and Macdonalds in 1478, and later between the Mackenzies and the Munros. The Mackenzies prevailed in both encounters. The ascent of Ben Wyvis (3429 ft.) is commonly made from Strathpeffer.
