Saint-Cast-le-Guildo suits a Brittany beach stay, with a main beach about 2 km long and views to Cap Fréhel. Saint-Malo-Dinard-Pleurtuit airport is about 22 km away. It fills up in summer, so expect crowds in the peak weeks.
Saint-Cast-le-Guildo is a seaside resort on the Côte d'Émeraude, with a port and a nautical centre. The Grande Plage runs for about two kilometres from the Pointe de l'Isle to the Pointe de la Garde, and Pen Guen beach, about a kilometre long, follows on past it. The Pointe de Saint-Cast has views towards Cap Fréhel, Fort La Latte and Saint-Malo. The homes are scattered around the commune, and most are small, sleeping around four. Winter is very quiet: the population is about 3,500 then and rises above 35,000 in summer.
Cap Fréhel is one of the views from the Pointe de Saint-Cast, a classified site that also looks towards Fort La Latte and Saint-Malo.
Three small coves on the Fresnaye bay at Saint-Cast-le-Guildo look across the water to Fort La Latte.
