Buy Fort Lucan vouchers for deals on Fort Lucan Day Tickets. Dublin’s biggest outdoor adventure centre, Fort Lucan, boasts an abundance of rides and games for action-loving children. Kids can splash into a pool of water from the 40-foot slide, speed down ziplines, traverse on aerial walkways, run amok in the army-style assault course and tear around on pedal go karts. Under fives can blast around in baby go karts, have shenanigans in the sand pit or behave like little monkeys on the mini climbing frame. Meanwhile, adults can take advantage of the blue Waterslide or Crazy Golf. Since all of this can be hungry work, the on-site cafe helps fuel the day's activities.
