Practical tips for Jersey
- Jersey issues its own Jersey Pound (JEP) at parity with British Pound Sterling (GBP); while British cash is accepted everywhere, spend your Jersey notes before leaving as they are rarely accepted in the UK.
- Getting around is easy with the LibertyBus network connecting St Helier to all key parishes, or you can rent an electric bike to cruise the designated 15-mph Green Lanes.
- Always consult local tide tables before exploring tidal causeways or beaches, as the ferocious outgoing and incoming tides move faster than a person can run.
Fun fact about Jersey
Jersey experiences one of the highest tidal ranges in the world, with tides rising and falling by up to 12 meters (40 feet), which nearly doubles the island's landmass at low tide!
