In reply to Edvenables:
> I know that rock climbing is new in Iceland and is being developed, and would really like to put up some new trad routes.
As with anywhere, those with local knowledge have a head start. And going on the info available on the internet, there is precious little rock climbing of any kind in Iceland, though new areas are being found and developed. The rock is either too young, or of the wrong kind. There is some gabbro however...
> Does anyone have any maps or information about cliffs and climbing there? I know there is some near reykjavik.
There's a reasonable amount of info available via Google, much of which has been linked to on threads on UKC, so it'd be worth searching this website.
> Also advice on the climate in Iceland in August would be useful, are there midgies/mosquitoes/ticks?
Last August, in the interior, the temperature rarely got above about 12. On the east coast, Egilsstaðir had a record breaking 26, iirc. Plan for Scottish spring, including the possibility of snow in the Highlands, and you should be OK.
Iceland is mercifully free of nasty bugs and insects. Small black flies can be a bit of a pest but they don't bite.
