In reply to Enty:
I've traversed the Bernia many times and always done the 'obligatory' abseil as it's made most sense to do so. I have looked at the alternative - which would be to stay on the crest - but looks pretty sketchy, so never done it.
With care, a 35m rope is just enough and will bring you onto the upper part of the ledge system below the ab station.
As a route it makes a very good solo day out for anyone happy and confident on exposed terrain with some technical sections. Route finding is relatively straightforward too.
There are plenty of other ridges in the region, some don't require abseils. The Toix ridge, which is part of the same rock system as Bernia, can be done without abseils. Or for a much bigger day out, check out the Benicadell ridge, no abseils required on that one either.
For more ideas have a look at: https://www.cicerone.co.uk/costa-blanca-mountain-adventures - which is on a sale price at the moment.
Hope that's helpful
