Kuala Selangor Firefly en-route Malawati Hill Day Tour is an exciting excursion to one of the biggest firefly colonies in the world. Fireflies locally-known as ‘kelip kelip’, perhaps Kuala Selangor’s biggest attraction. Admire the beautiful display of nature in awed silence, with the swishing sound of the water gently lapping against the sides of the boat breaking the silence. The experience is surreal to say the least; it simply has to be seen to be believed. As an added value, Kuala Selangor Firefly Tour includes en-route stop at Malawati Hill.
