The Cap de Creus is the easternmost point of mainland Spain — a windswept, treeless headland of folded schist and granite that ends in a lighthouse perched above the sea. The 14,000-hectare natural park covers both the cape and the marine zone around it, with footpaths through scrub and along the clifftops to a string of empty coves.
Drive or take the bus from Roses to the lighthouse car park, then walk. The Pla de Tudela trail, an hour's loop from the lighthouse, is the classic introduction to the geology — fields of contorted rock that look like a frozen sea. The restaurant at the lighthouse is a reasonable place for a lunch with one of the best views in Catalonia.
