Etel and Belz are typical Breton villages...
Fishing and walking around
Etel is at the entrance of the famous Etel ria. It's a nice harbour welcoming many fishing boats. The current is very strong at this point. Depending on local tide schedule, another site is worth seeing a bit further Pont Lorois. You can have a walk around there along the seashore and enjoy amazing landscapes in a very peaceful area. Belz is a typical Breton village with its granite built houses. If you're going to Lorient, you may cross this city to avoid the main road (N165). More information here
