The 150k loop is shaped like the figure 8, you get two chances to pass through Westport.
The first loop is the same as the 80k route but the second section passes through the Historical town of Newport, the Furnace lakes and stunning views of the Nephin mountain range. The further into Wild Nephin you go, the more remote the landscape becomes. Nephin mountain takes centre stage for the middle third of the route.
Once you turn for home, Croagh Patrick and Clare Island fill the horizon.
