Access to St Marys Island - Tide Times

Access to the Island is restricted due to the tide as the causeway is covered by the sea for aproximately 4 Hours at each high tide. (Aproximately 2 hours either side if the high tide time.)

The exact amount of time depends on the height of the tides and weather conditions.

A notice is posted beside the causeway which gives more exact times when the causeway will be covered

St. Mary\’s Lighthouse and Visitor Centre have a facebook page which gives the crossing times on their timeline. - For Link Click Here

Details are given below of the high and low tide times and are to be used as a guide only. Details posted locally should be checked. The table also give the height of each of the tides.
