Recommended sites in Brittany

Yes certainly, but what do you mean by "good" ?

 Do you want a big site with a water park and water slides for children  - Camping du Letty or Camping les Mouettes  - or a simpler site a short stroll from a rocky cove - Camping Pors Peron - or one close to Roscoff ferry port - Camping Trologot  or Camping Ar Kleguer - or a remote site in the dunes - Camping des Abers. . There are so many, and  some are more suitable for caravans rather than for motorhomes.

For a first visit you may like to tour and explore rather than just pick one. It's an easy area to travel around.
