Is there good climbing in Iceland?

There seems to be limited info on this site and in general on the web.

I was there years ago, and I saw a lot of columnar basalt, but I didn't see any climbers. I know there is some good ice, but am interested in rock.

I'm wondering if anyone can give me specifics.

Is there any good climbing? sport? Trad?

Where is the best climbing?

Is it worth lugging gear for a week long trip there in late June?

Thanks!

Yes there is some pretty good climbing, and a ridiculous amount of potential. You can read about my experience here, here, and here.
