Blue Tears Tour, Kuala Selangor

Step aboard a night‑time boat ride from the (Official Jetty) Sky Mirror Kuala Selangor and witness the Selangor River light up with bioluminescent plankton. These microscopic dinoflagellates emit an electric‑blue glow when disturbed, transforming the water into a shimmering carpet sometimes described as “blue tears”. Departures are typically at 8 PM, 9 PM and 10 PM, and the cruise lasts about 45 minutes with boat fees and insurance included. Tickets cost about RM 35 per person.

What you must bring

• Lightweight long sleeves and insect repellent: Protect yourself from mosquitoes and the evening chill. A light jacket is useful once the boat picks up speed.
• Camera or smartphone (no flash!) and a dry bag: The glowing plankton are faint; a camera with good low‑light settings helps capture the magic. Flash photography is prohibited, and a small waterproof bag keeps electronics safe.
• Water, snacks and optional change of clothes: There are no facilities on the boat; a spare outfit and snacks keep you comfortable.

Key things to know

‑ Duration, timing & price: The Blue Tears tour lasts roughly 45 minutes, departs at 8 PM, 9 PM or 10 PM and costs about RM 35 per person. Plan to arrive 30 minutes early for check‑in.

‑ Interactive experience: The crew sometimes provides long poles so visitors can gently swirl the water. Agitating the surface helps the dinoflagellates glow and creates swirling streaks of light. Patience is required because the plankton respond unpredictably.
