The summit is part of an east west ridge more than 3k long. At the east end is the rough tumult of ground dotted with lakes, ponds, cliffs etc between Coomcathcun and Cnoc Breasil. Walking away from this to the west you find yourself on a grassy ridge. It feels higher and airier than it is because of the lakes on either side (Cloonaghlin Lough to the south and Derriana Lough to the north)
The rising ground on the left is part of An Bheann Mhór (The Big Peak) a summit just a little higher than Coomcallee which is better known.
Access to An Bhinn Láir is no doubt possible from the roads to either of the loughs beneath it, however I got to it via some rough ground from Coomcathcun. Most probably also you could construct some interesting walks around the loughs, using An Bhinn Láir to gain height.
From most ways up you this summit will be able to savour the walk its long grassy ridge for its views and unusual lake surrounds. Linkback: https://mountainviews.ie/summit/424/comment/2486/
