The tallest tree is actually not easily accessible and not marked, due to those who discovered it but want to protect its health. When you stand and look up, you are looking so far into the sky that you really have a hard time fathoming how tall a tree can grow. you'll be moved with waves of emotion. As you stand there and look up at the massive fortresses that measure their lives in the thousands of years it puts everything in perspective.
Seeing the biggest, tallest and oldest trees in the world!
When you enter the silent forests, you gain a quiet moment free from noise.
