"What is it like to go out into Scotland's hills with little or no sight? Lindsay Cannon spends the day with a group of visually impaired walkers who rely on their four other senses." Blind Summit will be broadcast on BBC Radio Scotland, on Monday, 13 December at 1530 hrs, that is, of course, 1630 hrs in Chamonix! Lindsay recently spent a day out with visually impaired hillwalkers in the Cairngorms and recorded their experience for radio.
