I've thrown this page together just to give you some background on the site.
This is a link to a road map of the site St Mary's Island. there is a large pay & display car park, with a burger bar. Air is available from Deep Blue dive centre which is only a short drive away in Tynemouth (along the A1058 and right at the sea front if you need air on your way to the site).
