Caves to explore in Highland
Highland is a council area in the Scottish Highlands and is the largest local government area in the United Kingdom. Though relatively populous for a Scottish council area, it is also sparsely populated. At 9.0 per km2 in 2012, the population density is less than one seventh of Scotland's as a whole.
Smoo Cave is a large combined sea cave and freshwater cave. The cave was formed along two geological lines of weakness by a combination of erosion from the sea and an inland underground stream which has formed the innermost chambers. The cave can be thought of as two caves formed by different mechanisms which have joined together over time.
