Located at the Ebro Canyon, the walls of the High Ebro and Rudron gorges build a shocking scenery that must be seen and walked. If you have binoculars with you, you will probably be able to witness the griffon vulture nests, the colours of the rocks and many other birds. If you sleep there and you have enough patience to wait at night, you may find wild pigs and foxes among other animals.
The most interesting thing to see in Orbaneja del Castillo is its waterfall (more than 100 meter high) and walk along its urban center that preserves its mountain architecture as we can see in the casa de los marqueses de Aguilar, the casa de los canes and the casa de los probres (old hospital from the XVI century). In some parts of the town you can also find some circular stone tents and the church.
The must see from Orbaneja del Castillo is the Cueva del Agua: you need to pay a bit and during the weekends you may have to wait some minutes in the queue but it is worthy. The view from the top is really interesting as you can see a panoramic of the gorges. We find them similar to a castle which could justify the reason why a town without a castle (Castillo) is called Castillo. It is also nice to visit the Cueva de los jabalíes and the Cueva del Azar to see the cave paintings.
