North Pentland Hills, Edinburgh
The rocks of the Pentland Hills were formed during volcanic eruptions around 400 million years ago. We meet several different varieties of lava on this traverse across the northern slopes, with good views over Edinburgh and the Firth of Forth. Day walk, 5 hours, £14.
We will explore a variety of igneous rocks, formed by volcanic activity during the early Devonian period, around 400 million years ago. The rocks include basalt and andesite, and they have been affected by a long history of deformation and uplift since they formed. The views to the north, east and west give a good opportunity to appreciate the rocks and landforms of the Midland Valley.
We start near Bonaly Tower, with a gentle climb and walk around Torduff Reservoir then cross up and over to Bonaly Reservoir. Then the slope steepens as we start to work our way along the northern slopes of the Pentlands, with ever-improving views (weather permitting!), onwards to the high point at Allermuir Hill (493m). The route then takes us along the crest to Caerketton before descending to Hillend. Total walking distance is 8 km, duration 5 hours. This is classified as a Moderate Walk: not always on paths, may be rough or slippery underfoot at times. We will climb and descend moderately steep slopes, with the potential to slip or fall on wet grass and loose gravel. It may be wet, windy and cold especially at higher levels. Come equipped with strong footwear, good waterproof clothing, lunch and a drink.
The walk can be accessed by public transport from central Edinburgh – catch the Lothian service 10 to Bonaly, walk south up Bonaly Road, cross the City Bypass and take the first turn on the right. Carry on a short distance to the laybys on the left of the road. We will meet here at around 10:20am. Grid reference NT 212 679. At the end of the walk there are frequent services from Hillend back to the city centre.
Alternatively if you are travelling by car, meet at the end point of the walk, at Lothianburn, the lower car park at Hillend Ski Slope, on the A702 just south of the Edinburgh City Bypass. Grid reference NT 250 669. We will leave some cars here and drive to the start point at Bonaly.
