oronsay
I walked over to Oronsay at low tide about 3 years ago ... I would say forget it, but that was thinking as a PA28 and R172 (on steriods) person .... Definitely fallen into disuse (possibly even planted with potatoes).
Next time I'm over I'll chat with Alex the Laird ... see if anything is recoverable .. but considering £xmillion of taxpayers money has just been spent on upgrading Colonsay ...
