Tiff, a good friend of mine and his missus went there a few years ago. Its a very very cold place (not weather wise i mean), but it was something she'd meant to do for years. Very quiet and reflective atmosphere wise, with some very knowledgable guides.
Although she's read up on it for years, she said she wouldnt go again. Once was enough.
Very moving visit from start to finish.
Look forward to the pics when you return
