How can I get to the Scilly Isles from anywhere in the North of France in Summer 2012?

I am planning an amazing summer where I plan to backpack from the south of France all the way up to South West England. I really want to spend dome time on the Scilly Isles before hitting mainland UK, but I can not seem to find anyway of getting from France to scilly isles. I would feel silly getting to the south... show more I am planning an amazing summer where I plan to backpack from the south of France all the way up to South West England. I really want to spend dome time on the Scilly Isles before hitting mainland UK, but I can not seem to find anyway of getting from France to scilly isles. I would feel silly getting to the south coast of England and then going back down to Scilly.

Any ideas????
