At the Sam Mun Tsai beach in Hong Kong, bioluminescent phytoplankton are found in the water.
The Manly Beach in Sydney is also known for showing bioluminescent activity.
A vacationer paddles through bioluminescent phytoplankton on Florida's Indian River Lagoon by Cocoa Beach.

Here, La Jolla beach is lit up in neon blue. Some say this spectacle is the "ocean's version of the Northern Lights."
Red tides, an abnormal accumulation of algae, can make bioluminescence occur at additional sites too. A 2011 red tide in California caused this bioluminescent activity close to the beach.
