Well, both routes into Ronda are wonderful - you can't go wrong! If you stay on the Via Serrana, you have a
nice section in the Rio Guardiaro Valley going past Benaojan. (There is actually another option here if you have any particular interest in prehistoric cave paintings and that is crossing the river to the west bank so you can visit
Cueva de la Pileta on the way into Benaojan.)
If you take the two-day option, you first traverse
an arroyo that feels remote and beautiful and then from Atajate to Alpandeire you get to see the Genal Valley from the top. The next day you walk a higher level route into Ronda with some very nice geologic formations. Our journal shows
that stage in reverse.
