Night firefly watching cruise in Kuala Selangor

Admire the world's largest firefly colony in Kuala Selangor, where thousands of these insects light up the trees at nightfall. The tour begins with a visit to Fort Altingsburg, an 18th century hilltop fortress formerly used for the defense of the city. Tour its ruins, learn about its history and enjoy the panoramic views from the top. In the evening, take a boat ride through the mangroves to watch the fireflies glow in unison in the trees lining the river. Later, continue with another boat ride to see the well-known "Blue Tears", a natural phenomenon in which luminescent plankton dyes the water an intense blue color. The experience ends with a seafood dinner at a local restaurant in a fishing village, where you can taste the typical gastronomy and learn about the daily life of the area.
