Just east of Elgol is the Spar Cave, famously visited by Sir Walter Scott in 1814 and mentioned in his poem 'Lord of the Isles'. The 80m-deep cave is wild, remote and filled with beautiful flowstone formations. It is a short walk from the village of Glasnakille, but the approach is over seaweed-covered boulders and is only accessible for one hour either side of low water. Check tide times and route information at the tearoom in Elgol.
