Jersey is the largest of the Channel Islands and a British Crown Dependency located near the coast of France. Crime rates are very low, and the island offers a safe and welcoming environment for visitors. Coastal hazards including strong tidal movements, particularly around the island's extensive reef systems, pose the main natural risk; Jersey has one of the largest tidal ranges in the world, and visitors should check tide tables before exploring the coastline. Jersey General Hospital provides a good standard of medical care. Travellers should note that Jersey is not part of the United Kingdom or the European Union and has its own border controls.
