The journey then crosses the vast Landes forest – Europe's largest maritime pine forest – before reaching the limestone plateaus of the Loire Valley and the chalky cliffs of Picardy. Crossing the English Channel, the landscape changes to the rolling Cotswolds and finally the limestone gorge of Bath.
