Glen Lyon & Schiehallion Munros

6-7th April 2022


The Glen Lyon Four and Schiehallion


The circuit of the four Glen Lyon Munros is a very satisfying day out - Carn Gorm, Meall Garbh, Carn Mairg and Creag Mhor. There is a good track to begin with and a mountain path around aided by old fence posts that are useful in poor visibility.
These four Munros on the north side of Glen Lyon lie on a mostly broad and undulating ridge.
I've been around this circuit a few times and backed off in high winds once. However, for a great and long day out on a good day this place is amazing. In my opinion, a finer day out than the classic Lawers ridge. Here, you get more of the remote feeling. It's a circular horseshoe with easier escape routes should you want to shorten the day and you don't need a two car faff as you end where you began.
The one tricky part is a descent off Carn Mairg as It's a bit bouldery requiring balance and good footwork. In winter, the rime ice makes some wonderful sculptured coats on the fence posts.
But on the whole, It's a day for just being out there enjoying fresh mountain air and having a great long walk.
With excellent views over the glen to the Lawers range, and over Loch Rannoch, it's basically a really nice and mentally untaxing day when the weather is good. And you still feel you've earnt a nice meal out in Aberfeldy.

Schiehallion is set apart from the rest in the central Highlands and is visible for absolutely miles around. On the flip side this also means the views are absolutely extensive on a clear day.
This isolated location but relatively easy access meant Schiehallion was chosen by Charles Mason in 1774 for a planned experiment to estimate the mass of the Earth. However, Mason turned down a commission to carry out the work and it fell to Nevil Maskelyne and Charles Hutton to undertake it. The result was surprisingly close as confirmed by later experiments.
During the surveying of Schiehallion, Charles Hutton, devised a graphical system to represent surveyed heights which later became known as contour lines.
There is a good car park though it can get busy. This is a popular hill. The path underwent extensive repairs a decade ago but there are still rocky sections. My first visit to Schiehallion was at night and in the pouring rain. The sort of rain that seems to generate a mist of smaller rain as its falling so hard. Head torches simply reflected light almost like full beam headlamps in dense fog. But we made it and back again.
