Go to the place that Robert Burns went to in July 1796. This place was visited by people who wished to improve their health. Not much remains here to mark his visit other than a plaque to mark the occasion.
Follow the track south for a short distance until you find a large holly bush on the right. What you are looking for is on the north end of the holly bush on the stream side under a small pile of stones (access is easier if you go round the south end of the holly bush)
