Popular around Doo Lough
This plateau is a good place to pause and take it all in before the real climbing begins. It's a bout to get quite steep as you ascend 'The Ramp' up Ben Lugmore. Make sure you're prepared.

An incredible picturesque freshwater lake in County Mayo. It is 4 km (2.5 mi) long and 1 km (0.6 mi) wide. But forget the numbers and just feast your eyes on the spectacle of nature here - this must be one of the best Ireland has to offer.

A stark reminder of the dark history of these lands. During the Famine Years, almost 400 starving adults and children walked 10 miles from Louisburgh to Doo Lough, seeking food or a ticket to the workhouse. Many have died - but not on the walk to Doo Lough, but on the way back, as they were refused food or food, and needed to get back. It was then that they met with terrible weather, and many perished, from the combination of the bad weather, fatigue and exhaustion.

Ben Bury, at 795 metres (2,608 ft), is an awesome mountain. Getting here is a challenging hike and requires some good hiking skills, and certainly stamina, but the views are simply phenomenal.
