At the same end I'd like to encourage everyone to visit this place. It's really worth to be seen. I think there are no many places like that in the whole world. Everything you see when you travel across the world it's beautiful - and this is quite different. I can't say it's beautiful, but it's fascinating. And those trees! They just have to be seen.
And of course those trees are not the only one interesting place on the island. About more great and emblematic areas you can read on this site: http://myelhierro.com.
