Strong walking boots a necessity to do the 7km walk from Cadaques to the lighthouse at Cap Creus but the effort is well rewarded. Underfoot conditions vary from concrete footpaths in the built up areas around Port Lligat to loose shale where the narrow track loops up and down as you pass the various coves along the way. Encouragingly, the lighthouse appears in the distance from time to time to reassure you that you are on the right track; the red/green markers are very well appointed along the route for added confidence.
Allow about two hours but there are a number of sidetracks to be explored if one wanted to take a swim in one of the small bays en route.
The piece de resistance however has to be the bowl of fish soup and a beer, taken on the restaurant balcony on arrival, with the view of land and sea laid out before you. The restaurant does offer a reasonably full menu, including a selection of curries interestingly enough.
To return to Cadaques, a taxi is a possible option; the two hour trek back requires a certain level of fitness and stamina.
