The Old Military Road through the Wicklow mountains of Ireland

Hit the Old Military Road (R115) for a ridiculously scenic drive right through the heart of the Wicklow Mountains! This beauty straddles Dublin and Wicklow, and get this – it's one of the first purpose-built roads *ever* in Ireland.

Built way back between 1800 and 1809, mainly by soldiers (cool, right?), you'll even spot four old barracks from the road's construction crew along the way. Locals also call it An Bóthar Míleata. It’s paved the whole way, stretching nearly 40 km (almost 24 miles) from Rathfarnham, a Dublin suburb, down to the cute village of Laragh in Wicklow.

Now, fair warning: this route is narrow, winding, and can get a bit bumpy. Think permanent roller coaster! The bogs sometimes make the road sag, which is part of the fun, honestly. There are a couple of cliff edges, but nothing too crazy, so just drive smart. Visibility can be tricky on those curves. Oh, and it's been used in the Circuit of Ireland car rally, so that should tell you something!

Located inside Wicklow Mountains National Park, plan for at least an hour to an hour and a half if you’re driving straight through. Trust me, you'll want to stop. The views are incredible, no matter the weather. The landscape is rugged, and even in summer, be prepared for some serious crosswinds.

The road climbs up to Sally Gap, a mountain pass sitting pretty at 500m (1,640ft). In winter, be aware of potential road closures due to snow and ice. You might also find flooding or fallen trees sometimes. When it rains, the area turns into bogs and marshes, and yep, sometimes the road sinks a little! Adventure awaits.
