In reply to felt:
The big building and associated junk currently in there is a right mess. A mini Eden project style history/museum thing would probably be quite good.
parking / access would clearly be a problem, but maybe it could operate from a park & ride base in Ambleside or even out on the run into Windermere.
it may actually get some of the masses of folks who go on a ‘day out in the lakes’ (and never get more than 250yds from their car, see the house on the bridge and buy a Rab jacket), actually out into interesting bits.
a proper integrated public transport system using ferries, buses, narrow gauge railways, accessible footpaths & cycle ways would make lots of these type of things much more sensible.
the roads into grizedale for go ape etc are terrible. It would be far better for that area to be people & bikes only.
