Overview
Danigala, known locally as "Alien Mountain," is a unique circular geological inselberg near Maduru Oya. Its flat summit provides an uninterrupted 360° sky dome — making it one of the best natural observation platforms in Sri Lanka. The surrounding dry zone forest ensures minimal light pollution, and the site is popular among local amateur astronomy clubs.
