A BBC TV documentary may interest those who like to go walking in the Lake District, as it tackles the recent controversy over a proposed zip wire.

Tales from the National Parks is a three-part series on these designated areas and some of the battles that have been fought over issues of conservation and economic development - ones users such as walkers, climbers and mountain bikers may have strong views on.

The first programme looks at the attempts of the late Honister Slate Mine owner Mark Weir to establish a zip wire running down from Fleetwith Pike, a plan that divided opinion.

It will be shown on BBC Four at 21:00 BST on Sunday October 21st.

Further programmes will feature issues in the Peak District - the first national park in Britain - and Loch Lomond and the Trossachs - the first in Scotland.

The Honister zip wire plan was voted down by national park planners, but since then a new controversy over the national park has emerged after Natural England backed a blueprint to extend its boundaries and that of the neighbouring Yorkshire Dales.

Cumbria County Council opposes these developments and has vowed to fight against them.
