Yesterday, Pam and I waited by the roundabout hoping to see the horses and carriages coming from Jacarilla to Bigastro and then on to Orihuela.
They were expected at about 12:00am but of course that was an approximate time so we waited until 12:45 at which time we gave up.
So, were the carriages early or much later? It did occur to me that they may have taken a different route to the main road but that was not clear in the poster. In any case, I don't know of a different route from Jacarilla to Bigastro.
Whatever the reason, we missed them and so will have to wait until next year when hopefully they will process again around the Vega Baja.
