Just outside the town Pórtugos, next to the chapel is a beautifull "orange" waterfall located. The spring itself is located next to the chapel, but if you cross the street you will hear already the noise of the waterfall. Take the stairs down and you will enter a kind of open cave where the waterfall is coming down. The water is containing a lot of iron, which is resulting in the beautiful orange color of the waterfalls rocks and the river bed.
