The British Caving Association

How big is very big? :wink: We have one daylight shaft 285m straight down - no rebelay, can see the sun from the bottom... this is in the Peloponnese. It is said to have a twin in Crete, but I have not seen it. There is Provatina of course, originally explored by a group from the UK if I am not mist...

Thanks. It helps to get things into perspective to have the numbers. Our longest in Greece is about 14km with not many (less than five if I am not mistaken) above the 8km mark.

go on - write some numbers too... how long are they, in meters or feet?
