Enjoy an afternoon and evening tour to the dramatic 400-million-year-old Batu Caves and see hundreds of thousands of twinkling fireflies on a boat tour of the Selangor River. Continue to Batu Caves to roam in the prehistoric caves, after a climb of 272 steps. See some Hindu temples established here since the early 1900s, such as the temples of Lord Murugan, Siva, and Ganesh.

Before dinner, visit the Silver Monkey in Kuala Selangor Nature Park. The area is home to some cheeky Silver Leaf Monkeys, which are more friendly and tame than the monkeys at Batu Caves. Head next to Kuala Selangor, one of the most historic and conflicted areas during the early stages of the Malay Sultanate Selangor. It is also famous for its local Chinese food Restaurant, where you will enjoy dinner. A simple set dinner will be served in the restaurant situated on the Selangor riverbank. Finally, drive to Kampung Belimbing Fireflies Park. Quietly float out to see the incredible twinkles of the largest fireflies colony in the world. Marvel at the ability of these amazing lightning bugs to synchronize their light patterns before your return to Kuala Lumpur..
