Itineraries

Across the Gulf of Bothnia in four stops: the High Coast’s raised beaches, Skuleskogen’s crevices, the suspension bridge gateway and Kvarken’s multiplying skerries.

Around Monte Perdido: the Ordesa canyon, Gavarnie’s 1,500-metre amphitheatre and great waterfall, and the Brèche de Roland — the border gap you cross on foot.

Around Lake Fertő/Neusiedl in six stops: Rust’s storks, Purbach’s walls, the Fertőrákos quarry, Eszterháza’s Haydn rooms and Nagycenk — 120 flat km, ideally by bicycle.

Six stops in the Aggtelek and Slovak Karst: the border-crossing Baradla–Domica cave, karst trails above, and Slovakia’s aragonite and ice caves below.

Sigeric’s road from Canterbury to the Alps: Laon, Reims and Châlons, the Langres plateau, Besançon’s citadel loop, Lausanne and the Great St Bernard Pass.

The Limes left to right: Tyneside forts, Hadrian’s and Antonine Walls, Xanten’s re-raised town, the Saalburg reconstruction and the Danube capitals of the frontier.

The heritage spine of the Camino Francés: Pyrenean passes, pilgrim bridges, the cathedrals of Burgos and León, Gaudí at Astorga, and the granite finale at Santiago.

The Guaraní mission circuit across three borders: San Ignacio Miní, São Miguel das Missões, Trinidad and Jesús de Tavarangue — Guaraní Baroque in red sandstone.

North to south along the Wadden Sea: Denmark’s marsh park, Germany’s Halligen and Frisian flats, and the Dutch islands — one tidal landscape, three countries, six stops.

Two mercury towns, one World Heritage listing: underground at Almadén’s mining park, into Idrija’s 500-year-old galleries, and up to Gewerkenegg Castle’s museum.
