Despite its small size relative to other Disney parks, Disneyland boats tons of shortcuts, back walkways, and hidden paths. The smallest of these trails leads guests right to a land entrance, without the hub traffic. To find this hidden path, start in the Disney Princess Fantasy Faire. If you’re facing the central square, turn to the left and head past the stage. Once you reach the other side, you’ll arrive on the Hidden Path to Frontierland.
The path to Frontierland leads directly to the main entrance, next to the pin trading store.
While this small path isn’t necessarily more efficient than just taking the main hub into Frontierland, it’s a quiet spot and a good place to take photos of the hub and the end of Main Street USA. And if you want to really impress your friends with your park knowledge, start on the Frontierland path, cut through the Fantasy Faire, and take the Fantasyland path all the way to the castle!
this is not a hidden path it’s literally at the front
I don’t mean hidden as in “hard to find”, so much as “something most people don’t notice”. You’re absolutely right; the path is completely visible from Main Street. But most guests walk right past it without ever paying much attention to it!
