In the morning we woke up, ate breakfast, then drove up to the tower to see it more closely.
It certainly is impressive! I think it looks like a big tree stump. There are several hikes around the tower. We took the closest one to the base. It is paved the whole way around, so is accessible to just about everybody.
We spent several hours admiring and gawking before heading along to other sites.
Additional Info: Admission is $10/vehicle. Camping is $12/night.
