I liked the concept of the park which is kind of historic. There were a few surprises there. however you need to do the looking around since there are no guides and you may loose up on enjoying some of the park's features. More

A gentle breeze, tropical birds singing and mist in the hills. The drive here was almost as fun as seeing this wonderful scientific landmark.

We saw one elderly gentleman get back in his car because his knees could not handle the... More
