I just wanted to throw out this data call to what is out there. I know of Pendle Hill near Blcakburn and a few places in Scotland on some ski slopes. Are there any descent places in the Peak District? On the southern coast? Wales? Any information would be great.
Peak District - I was there for a great weeks holiday [Sept 2010] and checked out a few sites which on further investigation look like they are mostly regular PG sites and http://derbyshiresoaringclub.org.uk/ 'Members Only' but visitors can buy day/week passes (see their website).
More trips are needed when the weather is more flyable.
Not checked any sites on the South Coast.
