We are pretty well off in Northern Ireland for MTB trails, from short blasts to all-day epics, if you are willing to look around.
We are all experts in our own back yard, but the tendency is to just ride the same old trails over and over again.
So get your info here for something new, and hit the trails!
NOTE: The trails on this site have been ridden before, but you should not interpret their inclusion as an indication that mountain-biking is officially sanctioned on them. Seeking permission from landowners is your own responsibility, as is conducting yourself in a manner that is courteous, respectful to the environment, and conscious of the safety of others.
