Had an alfresco lunch today at Portmuck. Then went walking and learnt about the tombola. It was beautiful so peacful and the sun was out.Took a walk and got some lovely photos.Didn't want the bank holiday to end.Will definately go back my boyfriend was hoping to see puffins but only managed cormorants gannets and gulls.watched some guys fishing too and collected a few stones to take home as a reminder.

I walked Portmuck today and the weather was gorgeous, the sea was calm and the Ferries were coming and going, it was all too beautiful.

The only downside for me was that the walk didn't go on further, but after crossing the second field and reaching the boundary it looks like they are putting in another walk way. Has anybody else heard anything about this?
