As a part of my Manipur trip on 03rd June 2015, I was at Siroi Hills, Ukhrul, Manipur. Siroi Hills is located at Ukhrul, the highest hill station of the state is located at a distance of 83 kms. to the east of Imphal. Ukhrul is well developed and is a centre of a colourful warrior tribe, the Tangkhul Nagas. Siroi Hills and Khangkhui Lime Caves are interesting places for excursions. Siroi Hills: Ukhrul is also known for a peculiar type of land-lily, the Siroi Lily, grows on the Siroi hills at a height of 8,500 ft. This beautiful lily growing only in this part of world blooms during May-June. Tangkhul is one of the oldest and major tribes of Manipur.
