Propantes is a pothole on the mountain of Parnon within the borders of the Paliochori community of the Municipality of Leonidio in Greece.
All subsequent visits for many years halted at the deepest point leading off the main shaft at -310m.
Between 1998 and 2001, the depth of the pothole was surveyed to -316m following exploration carried out by SELAS caving club of Greece.
This exploration followed leads in the form of windows coming off the main shaft.
The pothole appears on many on-line deep cave lists (usually something reserved for caves deeper than -400m) as it had originally been erroneously reported as being deeper than the 400m required to be published in these lists.
