As an occasional backpacker, I've really gotten into car camping in remote locations. Its a whole different logistical challenge; fuel, water, gear, tools, etc. And from there you can day trip or overnight out as far as you want to go. Of course in the west/southwest its a bit different than the northeast.

I find its easier than planning a strickly backpacking trip because you can have pre-packed storage bins ready to go. Throw them in the car/truck and you're off.
