Alagalla trek (Potato Range) is one of the intermediate level hiking destinations in Sri Lanka. The mountain has two main entry points, one from Ihala Kotte railway station and other one is from Pilimathalawa via Poththapitiya. Either way is reachable within around 2 hours drive from Colombo. The Ihala Kotte route might be bit difficult for a beginner since the trek itself is a steep climb from the beginning. But from this year onward (2016), you will get a better aid since the local people put concrete steps in steep areas and made a path since there is a Stupa (Pagoda) built and open for devotees on top of the west ridge of the peak. This is much more similar to the upper part of Adams peak, Haramitipana.
