EuroVelo 1
From Aberdeen, the English section of EuroVelo 1 takes you along the north Scottish coast to Inverness. You will pass through Cairngorms National Park and Loch Lomond National Park and reach the Scottish coasts by following the Lochs and Glens Route. After going across the Irish Sea, the route visits the island of Ireland and then returns to the Welsh Coast at Fishguard, Pembrokeshire. It joins the Celtic Trail and continues to Wales and Bristol and through Exmoor National Park. Largely tracing the course of former railway lines, the last part of this route takes you across the breathtaking viaducts and bridges bequeathed by Victorian railway engineers, passing through tunnels carved under the hills of Britannia.

Following Europe’s mighty western border, reaching from Scandinavia, to South and Western Portugal, the Atlantic Coast Route visits the majestic fjords of Norway, the wild Irish coastline, the rough cliffs of Brittany and the sun-kissed beaches of Portugal, totalling 11,000 km. Along the way you will not only be seduced by bustling port cities and cosy fishing villages, but you will be impressed by dramatic landscapes and have the chance to enjoy the best seafood each country has to offer.
