Roque Cinchado is a cool rock formation in Tenerife that's like the island's mascot. It's the most popular place for photos, views, and hikes with some lava sills thrown in that got serious staying power against erosion. This rock was featured on the old Spanish banknotes together with Teide in the background, so it is an interesting and epic place to see!

But besides the rock, the nearby valley looks like a vast territory on the moon as you can see on my first photo.
