Kuala Selangor is a small coastal village northwest of Kuala lumpur. The village is renowned for the great attraction alongside the Selangor River that runs through the village. On this river you can spot the famous fireflies (Kelip-Kelip in Bahasa Melayu) during evenings/nights. The fireflies all are found on the mangrove tree species called berembang. It is said that this is one of the biggest firefly colonies in the world. If you want to check out the fireflies yourself, you should head out to Kampung Kuantan (9km from Kuala Selangor) in the beginning of the evening. There you can arrange an eco-friendly rowing boat; a local boatman (guide) will escort you. There are opening hours to take into account; you can visit the attraction between 8.00pm and 10.30pm daily (except for rainy days).
