"Southern Isles" - well Calmac group Islay, Jura, Colonsay, Gigha and Kintyre as the "Southern Hebrides", with Mull, Col, Tiree, Iona and Lismore as the Inner Hebrides. Various people then use Hebrides and Isles almost interchangeably and so I went for Southern Isles, sorry if that has confused! I would understand "The Western Isles" as a reference to the Outer Hebrides.
Walking on Arran - as we had heard lots of people talk fondly of Goat Fell we carried light weight walking boots all the way round with us, and were very pleased we did. The ridge between Goat Fell and North Goat Fell and then the drop down to the Glen Rosa col is lovely, and we only wished we had another day to do the other half of the horseshoe.
