Jersey and Guernsey, along with some smaller islands, were part of the Duchy of Normandy at the time of the Norman invasion of England. In the 13th century, Normandy itself became part of France, but the islands remained attached to the British crown as crown dependencies. Elizabeth II is their monarch, but Jersey has its own legal, fiscal and administrative systems and is not part of the EU.
If I had remembered all of this beforehand, I might have taken my UK bank card and a few pounds sterling when we visited last weekend. Luckily I was smart enough to take my passport, and so was allowed on to the ferry that sails from St Malo at a fairly ungodly hour of the morning.
We stayed with a friend in her beautiful flat overlooking the sea and this, coupled with the beautiful weather and the lack of outside communication (we didn't remember adaptors for our phone chargers!) meant that Jersey was something of a real paradise for us as well as a paradis fiscal for millionaires. We spent most of the weekend hiking along coastal trails and even managed a paddle, although my plans for sea-swimming were scuppered when the sun disappeared behind the clouds and the wind picked up on the only day I had my swimming costume in my bag.
We travelled back on the early boat on Monday morning and spent a day enjoying the equally gorgeous St-Malo before driving back to Paris in the evening. With my appetite for summer holidays well and truly whetted, it's been hard to go back to work this week!
