Suardalan is without a doubt a beautiful (located) bothy. Easy ish accessible, which is an advantage and a disadvantage at the same time. Lots of people visiting this bothy end up going there by car, hiking the last bit. Once there however you are faced with a beautiful old building with some ruins next to it. There's sheep roaming about in the fields next to the bothy and the mountains (including some Monroes) surrounding the building are beautiful to look at.
Inside the bothy there are multiple rooms and stoves. The basic bothy stuff. Wood to burn can be found within a 20 minute walk.
