Causeway Times for St Michael's Mount Open Days - Summer and Autumn 2020

The causeway provides access to and from St Michael’s Mount on foot.  It is covered by the sea at certain times of the day. 

St Michael’s Mount will only be open on the days and times listed here. There will be no public boats running.

On the days that we are open, visitors can stay for the duration that the causeway is uncovered, which is usually around 4 hours.
