Warning after walkers become sick from drinking river water

Some walkers tackling the West Highland Way have become unwell after drinking water from rivers, according to National Trust for Scotland (NTS) rangers.

They said at least nine hikers had suffered vomiting and diarrhoea while walking the popular long-distance route over the past month.

The rangers said the people had drunk water from rivers near Balmaha, a village on the shores of Loch Lomond.

Three of them had taken water from The Burn of Mar, and rangers warned that there were farm animals upstream in the area.
