The road through Doo Lough Valley is a quiet, narrow route with little traffic, allowing you to fully enjoy the wide sightlines over the dark lake and surrounding mountain flanks. Along the shore are several photogenic spots where water, light, and landscape come together beautifully. This passage logically connects to Delphi Valley, the climb to Doolough Pass, and the understated 1849 memorial, making this stretch one of the most impressive links of the entire route.

Benmore at 332 m (1089 ft) offers phenomenal views of the Benmore Ridge stretching along the Atlantic Ocean to the west all the way to Achill Head. It is a place of unbelievable beauty.

The summit is relatively easy to climb, but don't be fooled into thinking you can find a way up from the valley floor. The path disappears as soon as you start the ascent. Good mobility is essential to get up there, as there are several small scree sections along the way. The descent, on the other hand, is disastrous. There's no path at all, and you have to traverse a very unpleasant, steep slope through moss and bushes. It's recommended to split the hike if you only want to reach the summit. Start from the car park at Lough Accorymore and don't attempt the circular route to the top. I really advise against doing the circular route; you won't enjoy the hike otherwise, but the view is still worth it. Just follow the route marked at the car park by the lake.

Aasleagh Falls is a pretty waterfall not far from Leenaun. It's set in a typically beautiful and mountainous Connemara landscape, where the Erriff River empties into the Killary Fjord. The intriguingly named Devilsmother rises to the east, while Ben Gorm rises to the west. This part of the Western Way can be prone to flooding. If the trail is impassable, the N59 can be used instead.

Céide Fields is the most extensive neolithic site in Ireland. The ancient structures were covered by bog over the centuries and discovered when cutting peat in the 1930s. The area is dominated by dramatic cliffs towering over the Atlantic Ocean. Just off the coast is the distinct cliff of Downpatrick Head.

Welcome to one of the best views in Ireland. The views of the cliffs going up to Croaghan are just stunning. In my mine they rival Slieve League and the Cliffs of Moher.
