There are pitch and put courses everywhere in Ireland. Practically every town will have one. There's a links one beside Lahinch.
There are also longer courses called par 3 courses.
If you like to play a bit of pitch and put and then go for a pint, you could go to Glencullen, beside Johnny Fox's Pub.
There's also a fun one called The Creek near where I lived in Rathfranham. Anyway, some are just fields with flags in them, while others are much better.
