Hi there

If you just read back through some of these forums you will find loads of info about sites and good times to visit (Gerald Ponting's webiste has all the info with relation to the moon skim at Callanish) but I would also recommend getting hold of a book called "Lewis & Harris; History & Prehistory" by Francis Thomposn, which is a gazetter of sites on the islands. They were selling it on the Cal-Mac ferry from Stornoway but I also picked up a copy from a bookshop in Ullapool.

You're in for the trip of a lifetime, I envy you!!!
