I have a permit for the Whitney Portal area from July 8 - 11th. What I would like to know is whether or not that permit allows me trail access and overnight camping access to other parts of the JMT? I'm driving south from Sacramento in early July and would like to do some out and back hiking/tent camping near Bishop, Big Pine, Bubs Creek Trail, Shepherd Pass Trail, etc. Any information regarding whether or not I need a DIFFERENT permit and access points to the JMT from these areas would be very helpful. I've gone through three different books and can't seem to make heads or tails about all the different permits I might need! Thank you!
