Sheilin’ o’ Mark Bothy
Sheilin’ o’ Mark lies in the furthest reaches of Glen Mark at NO 337 827 and is seldom frequented save by coast to coast walkers and seekers after a quiet weekend.
Access
The easiest access to this bothy is from Glen Muick. Start as if heading for Lochnagar but, where you would turn right to reach Lochnagar or keep straight on to walk along the SE shore of Loch Muick, take an insignificant path to the left (that’s almost exactly SE for the navigators amongst us) and head up a small glen. Follow the path until it peters out and head over the hill (no path) to find the bothy. The hills in this area are relatively featureless and it is recommended that care is taken in navigation. (Which translates as: The author got lost here one dark Hogmanay night)
Accommodation
Sheilin’ o’ Mark is a single room stone-built bothy with a concrete floor. There is some basic furniture, including benches and a table, and a good fireplace, but the building is not insulated at all.
Fuel
There is no wood in the area, so it is a good idea to carry in some coal. The fireplace is a good one, recently installed after a stove proved impractical.
Water
There is a good stream just yards from the front door with clear water.
Toilet
There is no toilet here. Take the bothy spade for a walk well away from the bothy and any running water.

Visited it on a coast to coast once. None TGOC one mind you.
Aye, it does seem to get a lot of its visits from TGOC folk. Lovely spot whenever you go there.
Planning a stay there in May on my first TGO- Kenny very kindly says he’ll be there in advance wi coal! A true gentleman!
Hope you enjoy, Stuart. Getting a coal delivery is the icing on the cake!
Just needs updating to mention the stove has been taken out and its just the open fire now.
Good point! Forgot about that.
Hi … a friend gave me this link as I have a photo and couldn’t figure out where it was taken. It turns out it is Sheilin O’ Mark Bothy. Taken on a group outing in winter. Would you like me to send it to you?
Always good to see a bothy picture. The Scottish Bothies Facebook group might be interested too.
Had an overnighter here on a dreich weekend. First time for both of us. Braw wee bothy. We carried in 10k of coal so had a roasty toasty night. Definately no fuel in the area though. Got in without a problem but wouldn’t like to try it in the dark or in low mist. As it was we took bearings from the path end (y junction of streams) right to the bothy, just in case. You also need to trust your compass bearing as the bothy doesn’t appear until the very last minute!
I had that very problem the first time I went there – https://cairngormwanderer.wordpress.com/2011/03/03/63/
