Had a couple of weeks up there last year... Gigha is great apart from only half the strip was mown and was a struggle to get out. I'd highly recommend Glenforsa - nice long mown strip (circa 800m) and the Glenforsa hotel is literally 30 paces from the a/c parking area. The hotel is run by Alison & Brendan Walsh (well known pilot bloke) who are great fun. Lots of flying stories as bar is usually full of people who've flown in. Good restaurant. Nice rooms. They'll even lend you a car to get round the island. Highly Recommended
and will be back this year!
