It is just two hours: from 10.30am to 12.30pm.
It will start with an indoor introduction to Lichens, before we go out to see which ones we can find in Wenvoe.
No experience necessary - this is ideal for anyone wanting to find out about these fascinating life forms.
It will be led by Barbara Brown of the Natural History Museum's OPAL project.
Anyone can come and the course is free, but places must be booked.
