In reply to Gav_92:
I think it does depend a bit how things look with access, but I'm imagining Wales might stay closed for a bit longer than England and overnight stays might still be frowned upon for a while. With that in mind and trying to avoid the more popular locations I've been wondering about a walk round Gragareth / Great Coum in the Eastern Yorkshire Dales.
Then once the Lakes are a goer and more popular places acceptable it'll be Scafell from Langdale. When Snowdonia opens maybe around Carnedd Llewellyn (from the North East).
Then when overnights are OK a week in Scotland somewhere remote like around Glen Shiel or Assynt, which I've never been to.
Can't wait.
