Amazing views across the lake to the castle and the Vallymount Road bridge. Blessington Lakes is officially known as Poulaphouca Reservoir, and it's only one lake. Construction of the dam began in 1937 and by the time it was completed, and the valley flooded, it became the largest man-made lake in Ireland. It supplies water to Dublin and the water is used to power a hydroelectric power plant.

The Annacarney Brook is a beautiful stream that flows near the ancient Annacarney Sweathouse ruins. The brook's clear, cold water was historically essential, as it was the final stage in the traditional healing ritual: after heating up in the sweat-house, the patient would plunge into the stream's icy waters for a curative shock.

We did the walk clockwise. The first bit was not the best, but later when we reached the lake it started to be interesting. It could get muddy, so good shoes or change of shoes later is a good idea. It was a bit windy too, so good jacket is a plus. It's quite flat, nothing strenuous. We loved the part along the lake and river. Beautiful and quiet countryside. Nice trees and meadows. The village has a couple of pubs, a shop and friendly cafe (Cartwheel Cycle Cafe). We had a cuppa, pint, ice-cream and biscuits.
