Just some quick notes on bagging all tops on An Teallach in a day as I couldn't find much when researching it myself. When drawing this route up, it only came in at about 22km, but quite a lot of ascent. In the end, it clocked up 24km, 1800m of ascent and an elapsed time of 8 hours 30 - I took two substantial breaks. The following was my route:
The first sight of Corrag Bhuidhe was very reassuring. I swear, reading peoples reports has made me way more nervous than I should be about some hills. It looked exciting, but nowhere near as sharp of a ridge as I'd had in mind after a couple of days in the Cuillins.
From the sub top of Stob Cadha Gobhlach, and looking back at Sail Liath, I spotted a couple I'd overtaken in the boulderfield on its South Eastern flank. They made for a beautiful silhouette on the dark mountain against the hazy blues of the horizon. I continued along the ridge and decided against a direct climb of Corrag Bhuide as two gents were directly ahead of me with helmets on. Lacking a helmet, I decided I didn't want them kicking a rock down on me, so skirted round on the Southern bypass path. After a few minutes, I took the first gully up, and stopped for a chat with a gent who had camped out over night and caught the Northern Lights. I kicked myself for not asking if he'd post them anywhere. The gully popped me out immediately after the first pinnacle of Corrag Bhuidhe. I climbed up this from the other side, then followed the ridge directly along to the true sub top of Corrag Bhuidhe. Here, I met two lads who had come the other way and were stopping to get their drone out for a bit of footage. I'm not on any social media, so not sure if what they captured. I continued down from Corrag Bhuidhe, which was an easy scramble - personally finding it easier than the direct line of Liathach, and then walked up to Lord Berkeleys Seat. Having read how 'terrifying' this was I decided to dangle my legs over. I had zero fear until...
...a mountain rescue helicopter popped over the bealach between Sgurr Fiona and Bidean a' Ghlas Thuill. I took that as a warning from the mountain Gods to reign in my hubris and I pulled the legs back up, just after a peek down between my feet. What a view down!
I continued up over Sgurr Fiona, and immediately over to Sgurr Creag an Eich. Given how busy the main ridge was, this sub top was a wonderfully quiet spot to stop for a sandwich. I sat here for a good while watching tiny specks traversing Lord Berkeleys Seat and Corrag Bhuidhe. From here, the overhang looked spectacular. On the way back, I took a bypass path which saved me reascending Sgurr Fiona.
From the bealach where the helicopter had been I caught some more silhouettes up on Sgurr Fiona.
It was then a wee out and back trek to Ghlas Meall Liath, which was a fascinating hill given it was split into red and blue stone.
I continued back from Ghlas Meall Liath up to Bidean a' Ghlas Thuill, stopping for a sandwich and an extended lie down in the sun. The ridge looks spectacular from here.
From here, I headed straight North to pick up the last top of the day Glas Mheall Mor, ditching my bag briefly with the intent of returning to descend via Glas Tholl. This turned out to be a poor choice as from the summit of Glas Mheall Mor a direct descent South East would be quite easy - albeit bouldery - going. Retracing my steps, I returned to the bealach and dropped into Glas Tholl. The first part was really steep going but it was on a nice path. This was a nice route to descend but it felt like it would never end. I'd ran out of water at this point so plunged my head into the Allt a Ghlas Thuill on numerous occasions to cool down. Within about 50 metres of the roads were the thickest rhododendron bushes I'd ever seen. I took numerous wrong routes here, including looking for a foot bridge that Ordnance Survey thinks still exists.
How many times have I looked at a map and picked a route only to find out Ordance Survey is wildly out of date. If you find yourself here, retrace your steps to the open meadow and head North, from there you'll pick up a path to the road.
Once on the road, it's a short walk up the road back to Corrie Hallie. Overall, a very achievable route to pick up all tops and sub tops in a day.
