We did the Coasts & Castles in May, Edinburgh to Newcastle. There was a prevailing south-westerly wind, gale force at times, that made parts of the Edinburgh-Innerleithen stretch uncycleable. From Innerleithen to Berwick it was almost a tail-wind, then travelling south to Newcastle it became a sidewind. Either direction it would have been difficult at times.
We took the sleeper to Edinburgh arriving at 7am, so spent the morning exploring the city. Our first night was at Tweedside Campsite, Innerleithen. After that we couldn't find any campsites along the Tweed so headed for Hume, hear Kelso, where we thought we'd find a wild camp spot. A nice lady let us camp in her garden. Also, we planned to stay at the Beachcomber House Campsite, Goswick, near Berwick, but changed our minds when we got there (nuff said). There is a campsite at Beal Barn just up the road from the Lindisfarne causeway. We didn't stay there but it looked very nice (we didn't see it until the next day and ended up staying in the picnic field of Beal service station on the A1!) Next stop was Springhill Farm near Seahouses - brilliant campsite where we also checked into their bunkhouse to sit out 125mph winds. Last camping night was among the dunes on Druridge Bay. Spent our last night at a
Travelodge in North Shields. I'm writing the trip up for CGOAB but haven't got very far yet.
It is a really good cycle route - the roads are empty, the scenery is beautiful and the beaches are spectacular. We can really recommend it as one of the most enjoyable rides we've done.
