Car parking is not too difficult on Sundays, but a problem during a working week-day.
Lothian Bus 24 stops at the door; a 2-minute walk away by the Cameo cinema there are 10, 11, 15 & 16 from Princes Street ; also 23 & 27 which come up the Mound; and 35 & 47 come up Lothian Road and stop in Lauriston Place (and there are others!)
The church is normally only open at service-times.
There is level (wheelchair) access from the street to all public parts of the building except for the Lady Chapel which is up a few steps (but is open to the nave). There is one wheelchair-accessible toilet.
If you cannot manage steps, communion will be brought to you. This is a regular routine, so please ask a steward.
