Hikers have bushwhacked off-trail into dense vegetation to reach the tree, making many social trails. The tree has also been damaged by visitors who step on its base. The area around the tree no longer has ferns due to trampling, Arguello said.
"The social trails have grown in number, the amount of garbage has increased, there's human waste that has been seen and as more people go up to this tree, they create more social trails and all of that is having damage impacts to the vegetation, to the soils and, and all of the garbage just sits out there," he said.
The area has no cell phone reception and if someone were to get hurt, it would take a lot of time and resources to rescue that person.
That, paired with the trampling of the tree's base and the forest, led officials to declare the area closed — and impose a US$5,000 fine and up to six months in jail for those who hike there anyway, he said.
Arguello said that Hyperion visitors may be disappointed to realize the tree is not really that much to look at because, from its base, all they can see are branches.
"It's tall, but it's not really that impressive to look at from the base because you cannot see the top of the tree. All you can see are the branches of this tall, skinny tree," Arguello said.
Park officials are encouraging people to visit Tall Trees Grove, where there are plenty of established trails and visitors have access to many imposing redwood trees.
"You can walk the grove and then go picnic by the creek and splash and swim in the water. You don't have to scramble and bushwhack up to this tall, skinny tree that isn't that impressive," Arguello said.
