  • Take Me There

An exciting and endlessly interesting mountain to walk, hiking up An Caisteal provides a very real chance to bag two, if not three Munros in one expedition. This hulking, ridged peak lies in the beautiful Loch Lomond and the Trossachs National Park and you’ll find the summit at 3,264 feet (995 m) with jaw-dropping views of the behemoths surrounding it. 

With a name translating as ‘the castle’, this peak has an intriguingly craggy appearance from a distance and wonderful rocky outcrops near the summit, including the turret-like rocks. Most of the mountain is grass-covered, with no particularly technical nor overly-challenging sections. 

Fantastic views of the surroundings and the mountain itself

There are multiple choices for hiking trails up An Caisteal with many walkers taking the north ridge approach from Glen Falloch, via Sron Gharbh and Twistin Hill, the knobbly ridge to the castle. Should you be feeling exuberant, a classic addition is the neighbouring summit of Beinn a’Chroin, another Munro. The peaks are linked by a rocky col and you don’t lose too much ground in the descent. 

From Sron Gharbh, the views become magnificent but it’s only when you reach An Caisteal’s summit cairn that you can rest and truly admire the scrape-your-jaw-off-the-ground views. Peaks like Ben Lomond, Ben Vorlich and a lot of other Bens light up the landscape with Loch Long winding into the distance. On a clear day, you couldn’t count the mountains you can spot if you had an hour and a notepad. 

Late spring to autumn can bring exceptional hiking weather but conditions can be changeable throughout and snow can linger long into the year. Only experienced winter mountaineers should attempt the hike when snow and ice are around.

    An Caisteal is one of seven Munros in the Crianlarich range and a journey to its summit often involves bagging neighbouring Beinn a' Chròin too. The Munro is named for a conspicuous outcrop that is said to look like a castle. Hikers approaching from Crianlarich usually take the broad Twistin Hill ridge, which features a few rock steps but nothing too taxing.

  • Stay close to the path. Very boggy in areas. Would suggest Yeti Gaiters

  • Approaching An Caisteal from the north via Sron Gharbh and Twistin Hill. The ridge is beautiful, without giving the hiker any technical difficulty.

  • I don't know what possessed me to walk seven Munros that day but I did! Pushing 30km and with 2,500m of ascent, I started with An Caisteal (a Munro mountain standing at 995m) and finished with Ben More. As painful as it was, I have really fond memories of this area.

  • From the road this Munro is fairly straight forward to reach. Some airy sections of the path, but nothing to put off those who don't like exposure.
