What is the navigation like on the way - is it fairly easy or do I need detailed ordnance survey maps.
Any thoughts anyone?
I always feel uneasy without OS maps, and the only time I didn't use them I had to change my route because I tweaked my leg. That proved a bit awkward.
When I walked SUW I made my own strip maps (wide ones) out of 1:50000 OS maps. It cut down the bulk and the weight a bit, and I can stick the pieces back together with sellotape if I want to. I know that, 50 years ago, such vandalism would have got me drummed out of the Scouts, the church youth club, the RA and just about any grim-faced conservative institution you could imagine, but I did it, so there!
Generally, signposting is exceptionally good in the Borders Region, which is east of the main watershed, so you'll be fine as far as St Mary's Loch. It's less good in Dumfries and Galloway, but the only place I had any doubts about where to go was in the fields between Beehive Bothy and New Luce. There was no trace of a path on the ground, but visibility was OK and I figured it out from my broad strip map. Let me know if you want to use mine - save you some money!
