How nice that you are planning a cycling trip to Ireland!
First of all, we got a few handy resources to plan cycling trips
while on the island (clickable link). A great place to look for specific itineraries is the Sport Ireland website
. You can search by region and difficulty (since you are looking for short trails) and then download the .GPX file to use with an app that supports this type of file (GPX Viewer, Open GPX etc). There may be others apps like All Trails
which I really like (and it doesn't require to manually add your itineraries). Do you already know where you would like to go approximately?
In addition those cycling itineraries, you can also cycle one of our greenways
if you happen to be near one (such as the Kingfisher Trail or the Great Western Greenway for instance). Some tour-operators
even offers organized cycling trips.
I hope that gives you leads to start with, please get back to us as you are planning your trip :)
