We're well served by flights from the UK and and if you want to drive - it's a pleasant trip down!
We'd be delighted to receive visitors, bring a trowel!
A meander off the major autoroute from Boulogne-Bellebouche can be done in six hours. Same if you're coming from Calais and take the autoroute. I'd recommend the excellent viamichelin.com website for route planning - it gets things mostly right. Driving down does present the opportunity for some stops though and you may wish to take a more leisurely meander through the countryside - it's quite a nice drive.
This is a very easy way to get here, we're just four hours from St. Malo. The road network in Western France is superb, very lightly used and you have the choice of zipping along on deserted autoroutes or meandering down through the west and the Loire valley.
