Well, I live in Plymouth, so Brittany Ferries is the best option for me. Just a ten minute cab ride to the ferry terminal, get on board and I'm in Roscoff in a few hours.
I go on foot as well, so that saves a few quid for beer and food etc.
I can get a ferry ticket (return) for about £100 and a train from Morlaix to Le Mans is only a couple of hours.
The handy part is coming home. I get back, hot tired, dirty and hungry and I've only got a ten minute cab ride before I'm in a hot bath with some food in the oven.
Works very nicely for me.
Location is everything, Pilgrim. Get up, get in car, at campsite 40 minutes later. Perfect.

And talking of location, I have never figured out how this thread has ended up in "It happened to me."
