This one is only for experienced walkers and, indeed, experienced and careful swimmers. If you do manage to get there, though, it is well worth the effort.
Firrib is located in the heart of the Wicklow Mountains and you access it from the Wicklow Gap, which is one of the most scenic locations in the county. Not only do you need to be an experienced walker, you also need to be able to use a map and compass as Firrib can be tricky to find.
If you get there you will find a lovely tranquil lake set in spectacular surroundings. The water is cool and refreshing, just what you need after a hike across the bog.
Don’t be put off by the photos here – it doesn’t always snow at Firrib. They just show an old, grey haired fellow trying to be macho (God help him).
Remember lakes can be dangerous, so swim carefully.
From Dublin you take the N 11 to Kilmacanogue and branch off here onto the R755 which will take you through Roundwood to Laragh. At Laragh you go onto the R 756 and follow this road up hill to the Wicklow Gap. From the Gap you follow the tarred road up hill toward the Turlough Hill reservoir, about a 30 minute walk. When the road runs out you then need your map to guide you across boggy terrain to the lake. It takes a further 40 minutes.
