A very nice coastal walk. Even the short detour through the interior of the country was sometimes quite nice.

Located on the banks of the Jaudy, the Kerdalo Gardens are an essential site in your discovery of the Jaudy estuary. Created in 1965 by Pierre Wolkonsky on the ruins of an old farm, this 18-hectare English-style estate is home to around 5,000 different plant species that live together around numerous ponds and basins. The highlight of this space, however, remains the superb garden of four squares, made up of interlocking checkerboards of Italian inspiration. Recognized as a remarkable garden and listed in the inventory of Historic Monuments since 2007, it has been owned by Christian Louboutin since 2021.

This rock, topped with a sentry box, was used in the past to monitor enemy incursions from the small islands in the bay of Port-Blanc. Having been destroyed, the gatehouse was rebuilt at the beginning of the 20th century on the initiative of Théodore Botrel. He added two statues: that of Saint-Tugdual and that of Our Lady of the Sea. Source: http://www.tregor.fr/index.php/sites-remarquables/240:rocher-de-la-sentinelle-a-penvenan-port-blanc
