Muirahara Woods is a forest found outside of San Fransokyo.
According to Baymax's data, the place is a nice place to learn about nature first-hand, and is the home to many plants and animals. It is also the home of Ned Ludd, who ended up living in it after an incident that almost took his life.
The Woods' history goes as back as the early 1900's, when artist/scientist Lenore Shimamoto studied the plants in the forest and wrote about it on her scientific journal.
More than a century later, the woods were planned to be destroyed by real estate developer Ned Ludd, but one night while driving around it his car's brakes stopped working and almost fell down a cliff, until a meteorite emiting an electromagnetic pulse completely stopped the car, saving him. Ludd believed it was nature that saved him and completely retreated from the city and technology, deciding to stay and live in Muirahara Woods.
He however also became paranoid and began attacking its visitants, who he believed would try to harm the forest. Ludd's attacks eventually turned into an urban legend of a mysterious creature called "The Hibagon", with some people even taking pictures of the "creature".
Go Go Tomago also enjoys visiting the forest from time to time, but only by herself, as being there is relaxing and she enjoys watching and drawing birds.
In the self-titled episode of Big Hero 6: The Series, the forest becomes the main setting, when Fred and Hiro become curious about where Go Go decides to go when she doesn't want to be with her friends.
Hiro, Fred and Baymax are taken by Heathcliff in Fred's limo to follow her, and seeing her destination, they wonder what she could be doing in Muirahara Woods. The trio spy on her, but accidentally get lost while trying to hide.
Fred and Hiro are found by Ned Ludd, taken to his treehouse for safety after almost being attacked by a bear, where Ned explains his story. Hiro asks Ned to help them find Baymax, but upon finding him, Ned becomes angry to see he is a robot as he hates technology, then threatens to get rid of Baymax.
Go Go, Wasabi and Honey find their friends and plot to save Baymax, then eventually incapacitate Ned by ambushing him and throwing him down a hole, injuring his arm. The team promise to help him if he allows them to leave with Baymax, so Ludd agrees and upon being healed by Baymax, he immediately tells them to get out of the forest.
- Following the hybrid theme of San Fransokyo and its landmarks, Muirahara Woods is a cross between San Francisco's Muir Woods and Tokyo's Aokigahara Forest.
