@longleat diego You can see more on my review of the place: Rio Safari Elche - A MagpieGoose in Elche
Valencia is quite far from Alicante, as I would have done but it would be 3 hours on a train. Elche is hard to get to on foot, I went on bus then by taxi. Benidorm is very accessible by tram, so Mudomar and Terra Natura are probably doable.
