This is a Letterbox Hybrid there is minimal GPS usage, and there is a stamp in the box.
History:
From the given co-ords, the bridge/ viaduct should be visible. You probably drove under it on the way here. This interesting structure was once part of the Harcourt Street railway line, which ran from Bray to Harcourt Street. The trains ran for about 100 years between the 1850s and 1950s, but increased private car ownership eventually lead to the closure of the line. Recently, parts of the line have been re-used for the Luas Green Line.
Directions:
Your task is to find a way to the top of the bridge. From the co-ords you should see the rough track up. There is no need to trespass in order to do this! Unfortunately the interesting part of the bridge is no longer accessible (it was open for many years). Instead, the cache is located at the SE end of the bridge.
Once on top you can have a quick look at the fenced off area before heading the opposite way (roughly SE). Walk to the very end where you will be met by a red/ rusty fence, and you'll notice an ivy-covered tree to your left. The cache is at the bottom of this tree.
I wouldn't advise doing this cache at night, and doing it in wet weather could make it trickier. Also, the approach to the cache will change depending on the time of year the cache is done. While this cache isn't physically as difficult as its nearby brother it still shouldn't be underestimated. The final approach to the cache will most likely be very overgrown in the summer, and the descent from the bridge is surprisingly tricky.
