Ha, we must have been typing those in parallel! I imagine lochnagar might be a bit quieter than LG options, though I’ve only approached it from the east before.
And yeah, loads of bikes shoved into the heather around derry lodge with a lock thrown on when I was there last year.
Or park at the Sugarbowl and get into the LG via the Chalamain Gap
