Bioluminescence on the Beach

A guided night walk across the seabed at low tide to see glowing bioluminescent creatures, led by the guides who first discovered them.

As night falls and the sea recedes, star-like shapes of luminous green twinkle and sparkle in a few unusual spots at low tide. This "moonwalk" across the seabed introduces visitors to bioluminescent creatures and other marine life, led by the local guides who first discovered the phenomenon.

Within a few hours, the sea returns to cover the walkers' footprints by up to 40ft. Feet are likely to get wet, and Wellington boots can be hired. The walk crosses uneven terrain at night; walking poles and Wellington boots are available. Distance: 1 mile.

The guides walk in small groups, so booking is required. More dates and details of other seabed walks are on their website. Private walks can be arranged, depending on the tides and the moon.
