A dam near the original Hork-Bajir Valley.

"The colony of free Hork-Bajir live in a hidden valley created for them by a being called the Ellimist. Even if you know exactly where it is, it's hard to find. Your eyes just seem to slide away from it. Your mind just seems to want to forget it. It's the only place that the Hork-Bajir are at all safe from the Yeerks. Or from humans for that matter."

The Hork-Bajir Valley, also known as the Free Hork-Bajir Valley or the Free Hork-Bajir Colony, was the home to a number of free Hork-Bajir. The original valley was enchanted by the Ellimist to ensure their protection.[1][2]; however, the Hork-Bajir, along with Peter and Eva were forced to flee the valley in The Resistance after the Yeerks managed to locate it. By The Diversion, they managed to move into a secondary valley, although this one most likely lacked the protective charms placed on the original by the Ellimist. The Animorphs and their families, including Ax, moved to the valley after the Animorphs' identities became known to the Yeerks. After the end of the Andalite-Yeerk War, the Hork-Bajir were relocated to Yellowstone National Forest, where they received protected status.


Original Valley

"But even now, even knowing precisely where it was, even with all my hawk vision focused, all my innate direction-finding ability carefully attuned, I had a hard time finding it. Call it a spell. That's what the Ellimist had done: He had cast a fairy-tale spell over this place, making it almost impossible for any mere mortal to find it. The eyes slid away. The feathers did not feel a breeze that blew from it. The ears heard no sound that came from it. It was the valley of the Hork-Bajir. The free Hork-Bajir."

To protect the valley and its inhabitants, the Ellimist "enchanted" the valley to make it difficult to find. Even those who have visited the valley numerous times have difficulty not overlooking the valley.

Jara Hamee and Ket Halpak continued to bring more free Hork-Bajirs to their colony. Many Hork-Bajirs began families and for the first time in decades, Hork-Bajir born out of captivity. One of these children was Toby Hamee, a seer.

After Marco and his father had to fake their own deaths, they along with Marco's recently freed mother took up residence in the valley for protection.[3]

New Valley

"We get them out. All of them."
"Okay. Decision made. They'll be safest in the new Hork-Bajir valley. Marco's parents are already there. And the Yeerks think they destroyed it. We'll take my family last."
Tobias and Jake[src]

Not long afterward the Yeerks discovered the identities of the Animorphs, and they were forced to all relocate to the new Hork-Bajir valley, where Eva and Peter resided. Cassie's parents, Tobias' mother, Rachel's mother and sisters were all brought to the valley. However, Jake's parents and brother were apprehended by the Yeerks before the Animorphs could extract them.[4] Ax relocated his scoop and moved to the new valley as well.[5]

After the end of the war, the Hork-Bajirs were given Yellowstone National Park as a new home.[6]
