Directions to dive sites:

Website maintained by Anthony Patterson of Cork SAC: Here's his comments on the directions section:

I've added some basic maps support to the directions on the website,
so if you want a quick visual reference for one of our regular
divesites, go to http://www.corksac.com/local.html, scroll down to the
directions and click on one of the headers, e.g.
http://www.corksac.com/local.html#oysterhaven .

You should see a map showing you how to get there on Google maps. Some
of the roads we use aren't actually on the map, so I've shown
directions to the nearest point I could find.
