The main concern is ensuring you do not discover a tick attached to you,!! Most are not infected- but some are! Ticks of course are not just in Scotland . If you do have a tick , I suggest you visit a GP , with luck you will be prescribed antibiotics as a precaution. Believe me Lyme Disease is a serious matter . Take care cover up well when walking in long grass . Don't wish to appear alarmist but my son had Lyme Disease , not diognosed - he was on antibiotics for 3 months , prescribed too late. He was poorly but fortunately escaped reasonably unscathed. An infected person needs antibiotics immediately. Sorry to rant , but this post is purely to warn and protect people. We love. Scotland , both the highlands and the South West - Dumfries and Galloway . Go regularly but also take care and cover up on walks . Enjoy your holiday.
