This cache is hidden in the wooded area that runs along the edge of the River Forest housing estate in Leixlip. The cache name was coined by my son when he was 5 years old. While exploring this area, he dubbed it the "Garbage Festival" due to the abundance of sweet wrappers and fizzy drink bottles scattered around.
To find this cache, enter the woods at the given Trailhead waypoint. Be cautious as the ground slopes downward quite steeply at the beginning, so please tread carefully and wear appropriate footwear for the ascent and descent.
Once inside the woods, make your way down to the clearing where some of the "festival" remains are still visible—including the remnants of a child's bicycle. From here, pick up the trail running off to the left along the side of the hill. Follow this path, and it will lead you to the cache.
