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. Fireflies are also known 'Lightning Bugs' and they shine brightly at the night to attract a suitable partner. Apparently, they are able to shine during the day too but humans then cannot see it. They are only seen at night in and along the 'Berembang' trees along the Selangor River. We could not spot any in the palm trees or any other trees for that matter. Often their flashing becomes sychronised, the overall effect is just like the twinkling lights of a Christmas tree. A trip along the river banks at the Selangor River at night is truly magnificient, and definitely a great attraction that should not be missed. There are a couple of nice restaurants where they mainly serve fresh seafood. Restoran Kuala Selangor is where we enjoyed a very nice local meal at Pasir Penambang (1A, Jalan Bagan Sungei Yu). You can stay overnight in the village of Kuala Selangor or at the chalets at Kuala Selangor Firefly Park.
