Cliffs of Moher is about 3.5 hours drive from Lough Rynn and is a stunning place to visit if you have a chance to do so!!
This is another nice town to visit on the river Shannon. About 30 mins away from Lough Rynn
Galway is one of my personal favorite city, it has a bohemian flavour that is typical of the west of Ireland psyche: laid back, relaxed and ready for a party!
