The route: Starting at Blairpark Courtyard follow the road uphill towards Howcraig. As the track bears left continue north on the grassy path. Head north east across the col to Feuside Hill (431m) then south east to Irish Law (484m).From the summit of Irish Law take an eastward line off the hill and make for the gap in the fence. Continue over the heather moorland in order to reach the summits of Knockside Hill (446m). As there is no obvious route off the hill we advise you walk down to the river, crossing at the safest and narrowest point. If the river is in spate, cross higher up the valley.

Airplane wreckage is still present on the northern slopes of Irish Law. In 1948 a Vickers Viking aircraft bound for Renfrew airport struck the hill late one evening. Miraculously, all 20 passengers and crew on board escaped before the aircraft was consumed by flames.

The views from the hill top summits are fantastic. On a clear day, you can spot the iconic features of Ailsa Craig, Goatfell on the Isle of Arran and the most southerly munro, Ben Lomond.

Birds: Look out for hen harriers, raven, golden plover, grey wagtail and willow warbler as they fly across the moorland.

Vegetation: Sphagnum moss, cotton grass, purple moor-grass, common and bell heather all thrive in the exposed upland landscape.

NB map and compass skills are essential as most of the walk is not on tracks.
