Kampung Kuantan in Kuala Selangor is home to one of the world's largest firefly colonies. This tour takes you to see the fireflies light up the night sky on a cruise down the Selangor River. Along the way, visit Kota Melawati, an ancient fort built by the Malacca Sultanate, featuring historical cannons, the legendary 100-step stairway, the Royal Mausoleum, and the famous execution slab. Head next to the Kuala Selangor Nature Park, situated at the foot of Bukit Melawati, for some bird watching.
