Shooting up from a creek, the canyon walls are 50 feet high in places and completely covered in ferns and mosses, some of which are species that have been on Earth for hundreds of millions of years.

was shot here. Fern Canyon has also been home to a number of other dinosaur specials made for the BBC and IMAX. Compounding the whole otherworldly vibe, you might even spot a giant salamander!

. It can only be this green with lots of water, so expect to get wet, though there are footbridges in the summer. You can hike in-and-back, or do a full loop up and out of the canyon.
