I would be backpacking 30 miles in the Sierra in Yosemite National Park. If you're wanting to backpack in the Sierra, depending on the trailhead you wish to depart from, there can be restrictions. National Parks like Yosemite don't make it that easy to obtain permits. You must reserve them online and pick them up in person. The lines to enter the park can be very long, and it's not as straightforward as one would think. I will explain how I obtained my permit, and some tricks for getting a permit for Half Dome when you're planning on backpacking in Yosemite.
