The tides

The tides in Finistère

The tide is the rise and the fall of sea level caused by the gravitational forces of both the moon and the sun.

In Finistère this phenomenon is particularly interesting because of the coastline's shape and the possibilityit gives to access rocky islands when the tide is low or to practise shellfish gathering.


The flows can be strong (especially during spring tides) and the sea level rises fast.

If you decide to go shellfish gathering
  • gather information about the time of the high / low tide
  • check the weather forecast
  • don't go too far, especially regarding your own physical abilities and the ones of the people with you (children, elderly people)
  • begin your way back to the coast a minimum of 30 minutes before the rising of sea level.
