What is Biofluorescence?

Biofluorescence is the absorption of light at one wavelength followed by its reemission at a lower energy and longer wavelength by a living organism. It is usually a response to Ultraviolet (UV) light and comes in an assortment of bright and wonderful colours. 

Biofluorescence occurs in a variety of organisms including insects, plants, lichen, mushrooms, fish, coral, amphibians, and some species of birds and mammals. 

It is one of Nature’s greatest hidden secrets and an area that we have only just begun to explore, with countless discoveries yet to be made.

Guided biofluorescent walks

Join us for an unforgettable guided biofluorescent night walk in a diverse range of different habitats. Discover a secret world of communication, taking place right under our noses.

During the walk, you will have the opportunity to see a variety of biofluorescent organisms. Depending on the season and location we can expect to find biofluorescent fungi, flowers, insects, lichen, seaweeds and more.

Who is it suitable for?

Our guided biofluorescent walks are suitable for children over 8 years old, individuals, couples, families, and groups. We offer a variety of options to suit your needs and preferences, and can deliver a unique biofluorescent walk in almost any location. 

Unlike a lot of other outdoor activities, it is well-suited for those who are less active and may not normally take long walks outdoors.

What to bring?

Biofluorescent walks move at a slow pace so please make sure to wrap up nice and warm. More clothes are needed than for a normal walk outdoors. We recommend layering up so you can always remove or add a layer as required. We will provide you with a special UV torch and safety glasses to be worn at all times during the walk. 

  • Plenty of warm layers of clothing
  • Good sturdy footwear such as walking shoes, boots or wellies
  • A hat, gloves, scarf and double socks in the cold weather
  • Waterproofs
  • Medication 
  • A drink and a snack

Come and join us for a guided biofluorescent night walk at a wide range of locations in Norfolk, Suffolk and beyond. 

Private biofluorescent walks for groups of 1 – 15 people. Contact us today to make a booking.
