If you need a reminder that nature is awesome, here are some beaches around the world that naturally glow (发光). Time to add these to your travel list!

Gippsland Lakes, Australia

During the day, the Gippsland Lakes are like any other: you can swim, water ski, or sail. But at night, the landscape begins to glow due to bioluminescent algae (生物发光的藻类). In 2006, massive rainstorms caused large amounts of algae to enter into the lakes. It glows whenever the water is disturbed, but it has slowly faded with time, which is welcome news for the lakes’ ecosystem.

The Maldives

This glowing beach in the Maldives is just one of the attractive features of the nation. The sand on this beach glows in the dark because of sea shrimp (海虾). These tiny organisms give out blue light for up to a minute, lighting up your path as you walk across the beach.

Halong Bay, Vietnam

Halong Bay is one of Vietnam’s most popular tourist destinations, but it’s not just because of its famous islands covered in green rainforests. At night, boat tours take people out on the water to see the blue-green light from the algae.

Dongying, China

The dreamlike sea in Dongying gives us a strong desire to travel unlike any other travel destination. The glow-in-the-dark algae is found mostly on the rock formations along the shoreline, which gives them a blue-green glow. Plus, it acts as a natural warning light if you’re swimming at night.
