After Tregastel look out for signs for Landrellec (about 3 km after Tregastel). The beach and parking are at the end of the road. This is a protected area with several unspoilt beaches and a pretty coastal walk in both directions. You can also cycle along this coastal path when it is quiet. There is a café/restaurant next to the car park which does good food (Le Macareux). Having said that this is a great place to pack up loads of stuff for the day and take a picnic. Children will enjoy the rock pools. This is much quieter than other beaches in the area although it is probably best to avoid the first beach.
