The most common ascent of Beinn Achaladair starts from Achallader farm at grid reference from where it is usually climbed with the adjacent Munro of Beinn a' Chreachain which stands three kilometres to the north east. The farmer at Achallader kindly allows walkers to park in a field next to farm and they can show their appreciation by leaving money in an honesty box. From the farm Coire Achaladair is ascended to the col with Beinn an Dotaidh passing several impressive waterfalls on the way. From the col it is a three kilometre walk north to the summit with a vertical ascent of over 300 metres passing over the South Top on the way. The view from the summit gives fine views of Rannoch Moor, with the near at hand flatness of the moor emphasising the feeling of height.
