Hi Chris
We share your love of remote spots
A spot which we loved staying at is Gruinnard Bay, Laide. It is right on the beach with views out over Gruinnard island and the sea and mountains all around. The sites for tourers are right at the edge of the beach. The owners are very helpful. There is a picturesque ruined church and river adjacent to the site. Lots of lovely low-level walks in the area.
There are, also, some lovely sites off the road to Arisaig. Another favourite area of mine is Dumfries and Galloway not so remote as the North of Scotland but still beautiful. Some of my favourite sites there are
Castle Point, Rockcliffe, By Dalbeattie
Mossyard, Gatehouse of Fleet
New England Bay, Port Logan
As you like these type of sites I would highly recommend Brian Leahy's new book "Great Sea View Camping and Caravan Sites in Britain". This is a full colour revision of his earlier book "Sea View Camping and Caravan Sites in Britain" which had 400 site. The new book is very well laid out and with a colour photo of each site. The book has 150 of his favourite sites from his earlier book. It costs
