Layby on the road up to Los Guajares
If you don't know this route it could be a little tricky. At some point you have to get onto the old pre motorway road to Granada (the N323) There are two roundabouts where you can swap from the GR14 to the N323 on the way up to Granada. You can also follow sign posts to Los Guajares. If you put los Guajares into a gps it should take you there as long as you come from the south. The meeting point is just over the river in a layby.
Get directions from where you are now.
