On Saturday the 8th of September, i couldn't have asked for a better day to go up 3 rock mountain to spend the day on the bike. 3 rock has to be one of my favourite places to go mountain biking in Ireland. Its perfect for everyone. The mountain biking tracks are all purpose built, man made trails and are kept in perfect condition. There are many trails on the mountain, these go from road trails, cross country to the toughest downhill trails. the cross country trails are top notch tracks that can be used and engoyed by first timers and even the best out there!! 3 rock is in the dublin mountains and is open to the public. if you decide to use this mounain dont forget protective gear, its essential !!!
