I would suggest checking with Algar Waterfalls that they’ve got some water, we last went in February and water was quite low, we have been twice previously over the years and they are spectacular so we’ll wortg checking as it’s quite a journey into the mountains. Guadalest is always spectacular as are Aqualandia water park, Mundomar great sea life centre and Terra Mitica not quite Alton Towers but still a good day out.
