Practical tips

To reach these places, the STAR network (Rennes public transport) serves the city center and Les Gayeulles well. For Janzé and La Chapelle-des-Fougeretz, a car is often necessary, although shuttles may be available during school holidays. I recommend checking the specific opening hours on each venue's website, as they can vary during holiday periods. Remember to book ahead for swim schools like Keraqua or Aquaschool, as spots fill up quickly.
