Waterfall Safety and Common Sense

Glenmacnass Waterfall is a large cascade seen right off the Old Military Road in the heart of the Wicklow Mountains just south of the city of Dublin.

The waterfall certainly looked impressive with its combination of slope, width, and cumulative height as the River Glenmacnass dropped some 80m according to Gaia GPS.

Unlike many of the waterfalls that we visited throughout Ireland as well as the UK, the thing about witnessing this waterfall is that it’s free.

However, getting close to this waterfall involves hopping the stone fences and trespassing since it resides in a private farm.

That’s why we were relegated to seeing the Glenmacnass Waterfall from the Old Military Road though I did see some people scramble around the waterfall at their own risk.

Indeed, this is not a formal hike though there is a more famous one to the Lough Ouler (i.e. the Heart-Shaped Lake; taking typically over 3 hours).

Speaking of hiking, from the free car park upstream from the top of the Glenmacnass Waterfall (see directions below), we pretty much went about 800m downhill before turning around.

Along the way, the views varied from looking straight over the top of the waterfall to more angled profile views before finally getting a direct (albeit distant) view of the same waterfall.

The walk downhill (and uphill on the return) along the Old Military Road was typically met by a handful of vehicles going in either direction with little to no shoulder to get out of the way.

So we definitely had to make sure we stayed off to the side of the road before continuing to explore what views we could attain.

In any case, we wound up taking our time checking out the falls, and ultimately we had spent about 50 minutes away from the car (though it could have been less than that).
