Adrian Chiles asked his blind guide if he was aware of any charity that paired blind people with those who would like to walk with them (How do you describe the view to someone who can’t see? I couldn’t even do justice to a canal towpath, 1 May). He says: “I hope no blind person is missing out on the simple joys of a good walk for the want of guides who may themselves be missing out on the chance to see the world better.” He may be interested to learn that the Winslow District Ramblers’ Group – which covers the area where Adrian was doing his walk and is affiliated to the national Ramblers charity – hosts an annual walk for the London Blind Walking Group. Clare Butler Steeple Claydon, Buckinghamshire Adrian Chiles should have asked Amar Latif, who he did a TV series with, about walks for blind people. He is the president of Ramblers – a charity dedicated to removing barriers so that everyone can enjoy walking in green spaces. Its website gives details of how to support those with visual impairments. In the capital, London Blind Ramblers aims to fill this need with local groups that host walks and provide guides.
