There's a brilliant picture of Tilly Parkins climbing on Moon Hill Crag, Yangshuo, China, in today's Guardian. The 2009 Yangshuo climbing festival takes place from November 13-15 to promote 'sustainable sport climbing'. Apparently this means that all money raised via festival entry fees will be donated to 'crag preservation and development projects plus those that encourage a long-term collaborative partnership between climbers and the local community.'
For a more detailed explanation of what exactly sustainability and climbing means, take a look at Dave Pickford's piece that appeared on the British Mountaieering Council (BMC) site, last year.
