The area is of particular interest to geologists, with some of the oldest rock formations on earth. The area was studied and mapped by the eminent geologists Peach and Horne some 86 years ago, they even stayed at this hotel. Traces of early man, wolves and bears have been found in the local caves (there are 48 caves between Inchnadamph and Knockan - however most are "wet" caves). A trip to the famous Smoo Cave at Durness is well worth a visit (a huge limestone cavern with three compartments).
