In reply to JJSegarty:
I know it won't help much, but I'd suggest that you don't concentrate too hard on doing the walks everyone else does. Theres no harm in doing them, but its good to get in some walks that fewer people do, if nothing else this will give you a good subject for the chat!
So:
-Scotland
Kintail: 5 Sisters, 3 Brothers, and also Forcan Ridge, you can do them all on separate days, or combine the sisters and brothers into one hell of a monster day).
Aonach Eagach in Glen Coe
Blabheinn on Skye (may be more of a mountaineering route rather than ML, but still shows good experience)
An Teallach in Fisherfields (North Scotland)
-Wales:
Rhynogs (just south of Snowdonia)
Snowdonia: Snowdon Horseshoe, the Glyders (include Tryfan and Y Garn if you have the energy), the Carneddau,
-England:
DARTMOOR!!! Most people ignore it ("not high enough blah blah blah, but one of the hardest place in the UK to navigate especially in the fog)
Peak District: park in Edale, up Grinsbrooke Clough, onto Kinder plateau, down Jacobs ladder.
Everyone will suggest something different. Choose an area, look at the maps, find something that looks interesting, do the walk, let us know!
