At its highest point, Piedra de Penol is just over 7,000 feet above sea level and was first climbed in the 1950's. Today there's a resting place and even a little gift shop at the top. Whoever runs it must be in incredible shape!
It's said that this was formed by a cave collapse in 263 A.D. Today it's used frequently by stunt fliers trying to get through the narrow opening. Amazingly, there are 999 stairs leading up to the top. I feel bad for the guy who had to count them; must have needed to start over many, many times!
I have to admit I'm not 100% sure what this place actually is, but I want to see it. Basically I think it's a museum/resource center for architecture and architects. They have a lot of interesting programs and exhibits.
We know what you're thinking and yes, this is a drain pipe, and yes, this is a hotel. While the room is private the "facilities" are in a public part of the park. Interestingly, guests pay whatever they want--there is no set fee so the rates are up to you!
In addition to the novelty of having a giraffe occasionally peek through the windows, this hotel is an absolute stunner. It was built in the 1930s and has a wonderfully cozy charm about it. This is definitely on my bucket list.
