In centuries past, wells were commonly believed to cure afflictions. Judging by the shimmering rosaries, multicoloured rags and trinkets bejewelling nearby bushes, many still believe this to be true of the cupboard-like Doon Well.
A sign points to the overgrown Rock of Doon, which has some far-reaching views. This is where the O'Donnell kings were crowned – presumably so they could get a squiz at what they were inheriting.
Take the signposted turn-off from the N56 just north of Kilmacrennan. The well and rock are about 1.5km north of the village.
