In reply to liam:
About a week ago, I spoke briefly to a climber who had just been out to El Chorro.
Access to the walkway itself is still off limits and there is a hefty fine if you're caught. However, many climbers are still heading out on to it and a couple recently caught on it were escorted back to their nearby accommodation and given a telling off, but no fine.
I don't think access to the railway tunnels has changed. This is still illegal.
