In reply to Dafer4:
Hi,
The climbing's not particularly special nearby to Edinburgh, but there is some single-pitch fun to be had at trad venues like:
The Souter - a sea cliff, with a good stack, an hour's drive to the south
Limekilns - short, polished, but good quality (anciently) quarried limestone
Aberdour/Hawkcraig - a very accessible semi-tidal sea cliff, with good routes in the lower grades
Traprain Law - very polished, but with good easy routes in a nice setting
Northumberland crags - lots of very short, but good quality sandstone trad routes, two hours drive south
Dunkeld - An excellent roadside schist crag, about two hours'drive north.
If it's fairly dry, all the above should be fine to climb in March. There's more info on them in the database on here.
Enjoy,
D.
