Now there is a $80 America the Beautiful Federal Lands Recreation Pass good for entrance to all National Parks, National Forests, BLM, US Fish & Wildlife, and Bureau of Reclamation sites for one year from date of purchase. If you're disabled, you may want to get an Access Pass which are free and good for a lifetime. If you're 62 years of age or older, a Senior Pass can be purchased for $10 and they're also good for a lifetime. Click here for more info on fees and passes.
Existing National Park Passes and Golden Age/Access/and Eagle Passes will be honored until they expire.
Thanks - I updated the "Red Tape" section.
If your mentioning only the Sequoia NP boundries and leading particular for the area, I should mention that Courtright is not within it's boundries but rather Sierra National Forest boundries.
