how to go: best to take the night train to paris having breakfast at gare du nord and with the next train to rennes. nice trip but takes a while. quicker by plane but mind the climate.what to do: beginning of december (3. – 6.12.) a must – the festival transmusicales de rennes. this year featuring miss platnum, white rabbits, yann thiersen, monosylabikk, chris de luca, the residents and many more.
