On our second-to-last day, we went up to Bukit Malawati and Kuala Selangor to see the world’s largest firefly colony and the effervescent Blue Tears boat ride.

The town of Bukit Malawati was small and nondescript

It was an old fort that sat on the Selangor River and overlooked the Straight of Malacca

There were hundreds of monkeys begging for food.

As it got dark, we went to the jetty to board our boat to see the fireflies and “Blue Tears.” - "Blue Tears" water is a natural glowing phenomenon in the ocean caused by microscopic, light-producing organisms called bioluminescent plankton or dinoflagellates

The next morning, we had breakfast and flew home.

We went uphill from the town to the Altingsburg Lighthouse

After the monkey adventure, we went for dinner on the river.

Our boat trip was disappointing. We watched the fireflies from our boat for about 15 minutes, and the driver couldn’t find the “Blue Tears” that evening.
