A fine walk leads west from Adisham along the ridgetop towards the village of Idalgashina through the Tangamalai (or Tangmale) nature reserve (open access; free), home to plentiful birdlife and wildlife including lots of monkeys. The path starts just to the left of the Adisham gates and runs for 3km through patches of dense subtropical jungle full of grey-barked, moss-covered weera trees alternating with airy stands of eucalyptus. The track is reasonably easy to follow at first, though it becomes indistinct in places further on (the directions below should suffice, though). After about 1km, the path comes out to the edge of the ridge with panoramic hill views stretching from Pidurutalagala and Hakgala near Nuwara Eliya to the left, Bandarawela below, and right towards the distinctive triangular-shaped peak of Namunakula, south of Badulla. Below you can see Glenanore Tea Factory and (a little later) the rail tracks far below (they will gradually rise to meet you).
From here on, the path sometimes sticks to the edge of the ridge, sometimes turns away from it, undulating slightly but always keeping roughly to the same height. After a further 1.5km you’ll see the rail tracks again, now much closer. Over the next 500m the path winds down the edge of the ridge to meet the ascending rail line, at which point there’s a wonderful view south, with impressive sheer cliffs to the left framing views of the lines of hills descending to the south, and the flat, hot plains beyond. From here you can either continue along the tracks to Idalgashina (about 6km) and catch a train back, or return to Haputale along the tracks (about 4km).
