Here you walk down and onto wooden boards around the edge of the rock, above the water, which at this time of year remains very low. Continue along the boards and you come to a suspension bridge, go over here and you will go into a small cave. It only goes dark for a moment, so enter, focus and the light will shine at the other end.
Once through the cave you have a couple choices.
The first and most popular is to continue down, over the bridge and around the edge of the old Mill.
There is a path that leads back up into the bottom of Castril (quite steep) where you can enjoy a drink at a local bar such as Emilios, the Zafra Bar or Romeros.
Alternatively, once you leave the cave you can continue into the valley walking as far as you wish, then cross the river and return.
For those who are less energetic, once through the cave, enjoy the waterfalls (dependant upon flow of water) then return the way you came…..
The walk that takes you around the old Mill (now coverted into rural accommodation) can be done in around 20 minutes, but if you have smaller children with you, can take up to an hour to complete…..be warned the children are most likely to moan in the heat and keep asking "are we there yet"!
Don't forget to take plenty of water with you!
