Atlantic Coast Route
The wildest and hilliest UK ride — a discontinuous Atlantic arc in three legs, riding several signed NCN routes. In Scotland it runs NCN 1 from Aberdeen to Inverness, the Lochs & Glens Way (NCN 7) past Loch Lomond to Glasgow, then the Ayrshire coast to Cairnryan. A ferry crosses to Belfast for a Northern Ireland leg to the Donegal border at Strabane, and after the Irish section the Rosslare–Fishguard ferry lands you in Wales. From Fishguard the Celtic Trail (NCN 4 & 47) crosses Pembrokeshire and South Wales to Newport, then Bristol, Somerset and the steep Devon Coast-to-Coast (NCN 27) to Plymouth, where the Roscoff ferry carries on to France. Hard: the Cairngorms and Highlands, then the notoriously steep Pembrokeshire and Devon hills. The ~1,700 km covers all three UK legs — about 790 km in Scotland, 180 km in Northern Ireland and 730 km across Wales and England.
