The Environment

A Coastline Shaped by Tides

The Intertidal route follows Jersey's eastern coastline. This dynamic, living environment is shaped by one of the largest tidal ranges in Europe.

Twice each day, vast areas of reef and shoreline are exposed and submerged, creating rich habitats that support marine life, coastal birds and fragile ecosystems.

Why This Coast Matters

This stretch of coast is ecologically important not just for Jersey but for the wider Channel Islands.

Along the route you'll find:

• Intertidal reefs and rock pools
• Shallow bays and sandy flats
• Seagrass and seaweed habitats
• Feeding and nursery areas for fish and birds

These environments are productive, beautiful — and easily damaged if not treated with care.

Water Quality & Coastal Health

Bathing water quality around Jersey is closely monitored, particularly in popular coastal areas.

Conditions can vary depending on tides, rainfall and seasonal factors. We encourage everyone using the coast for running, swimming or recreation to stay informed.

Responsible Use of the Coast

For runners, swimmers and coastal users

The Intertidal route is designed to celebrate movement through nature – not over it.

Please help protect the coastline by:

• Staying on established paths where possible
• Avoiding disturbance to rock pools and marine life
• Respecting wildlife, especially nesting birds
• Taking litter home (including biodegradable waste)
• Being mindful of tides, reefs and rapidly changing conditions
• Giving swimmers, walkers and wildlife space

• Share responsible coastal use with others

Protecting this coastline ensures it remains open, wild and alive for generations to come.
