Cairn Toul is often climbed in conjunction with other peaks. From the south, it may be combined with The Devil's Point, which lies about 2.5 kilometres south-southeast. Alternatively, it may be climbed from the north, including Braeriach and Sgor an Lochain Uaine. Both routes are long days by Scottish standards: around 15 km (plus return) regardless of whether one starts from Coire Cas above Speyside, or Linn of Dee to the south.
