INTRODUCTION
‘Morceaux de France tombés à la mer et ramassés par l’Angleterre.’
‘Pieces of France fallen into the sea and picked up by England.’
Victor Hugo
Small and often very busy, but also beautiful and abounding in interest, the Channel Islands are an intriguing walking destination. The self-governing ‘Bailiwicks’ of Jersey and Guernsey owe their allegiance to the Crown and seem outwardly British, but are in fact an ancient remnant of the Duchy of Normandy, with Norman–French place-names very much in evidence. For British visitors it is like being at home and abroad at the same time. French visitors, however, find it a quintessentially British experience!
Walkers will find magnificent cliff and coastal paths, golden sandy beaches, wooded valleys and quiet country lanes. Flowers will be noticed everywhere and there is a rich birdlife. There are castles, churches, ancient monuments and fortifications to visit, as well as a host of other attractions. There are efficient and frequent bus services, and easy onward links by air and sea between the islands. This guidebook describes 24 one-day walking routes on Jersey, covering a total distance around 225km (140 miles), plus a long-distance coastal walk around the island, measuring almost 80km (50 miles). There is also a note about the Channel Island Way, a long-distance island-hopping route embracing the entire archipelago, covering 178km (110 miles).
Location
The Channel Islands lie south of Britain, but not everyone immediately appreciates how close they are to France. The islands fit snugly into a box bounded by lines of longitude 2°W and 3°W, and lines of latitude 49°N and 50°N. This puts them well and truly in the Golfe de St Malo off the Normandy coast of France, The French refer to them as Les Îles Anglo-Normandes, and that is the clue to their curious place in geography and history. They are the only remnants of the Duchy of Normandy to remain loyal to the Crown.
Jersey is the largest and southernmost of the islands, yet has an area of only 116km2 (45 square miles). No point on the island is more than 3.5km (2 miles) from the sea, yet it can take weeks to explore the place thoroughly.
Geology
In Britain virtually every major geological period is represented. Channel Islands geology is more closely related to structures in France. Rocks are either very ancient or relatively recent, with hundreds of millions of years missing from the middle of the geological timescale. Fossils are virtually absent and the amount of sedimentary rock is quite limited. Most of the area is made up of ancient sediments and igneous rocks which have been heated, warped, crushed, deformed, melted and metamorphosed. Further intrusions of igneous rocks cause further confusion for the beginner, but there is a basic succession that can be presented in a simplified form.
The most ancient bedrocks in the Channel Islands are metamorphic and metasediment rocks known as ‘Pentevrian’ – a term used in neighbouring France. Ancient gneisses, often containing xenoliths of other long-lost strata, feature in this early series. Dating rocks of this type is possible only by measuring radioisotopes in their mineral structures, which suggest dates of formation ranging from 2500 to 1000 million years ago. The oldest rocks occur in southern Guernsey, western Alderney and possibly on Sark.
The ‘Brioverian’ sedimentary series dates from 900 to 700 million years ago. It is represented by a broad band of mudstones, siltstones and conglomerates through Jersey. In Guernsey only a small area in the west contains these rocks, though in an altered state. One of the problems of dealing with these sediments is that even while they were being formed, they were being deformed by earthquakes, heat and pressure. Fossil remains are few, and in fact are represented only by a few worm burrows.
Following on from the formation of the Brioverian sediments, a series of igneous intrusions were squeezed into the rocks around 650 to 500 million years ago. Interestingly, both granites and gabbros were intruded, along with intermediate rock types. A host of minor sills, dykes and pipes were injected to further complicate matters. These tough, speckled, igneous rocks have been quarried all over the Channel Islands for local building and for export.
