Easiest and cheapest way to St Omer

Hi,

Just need a bit of help. In July I will be travelling to St Omer for a course but need to find the easiest and cheapest way to get there. A flight to Paris is an option but does anyone know how I would get from Charles De Gaulle Airport to St. Omer?

Thanks

Hannah

You may be est to Eurostar to Lille %26amp; get a train to St Omer?

This is likely to be the quickest %26amp; cheapest.
