I'm flying from Ireland to San Francisco and then renting a car to get to Yosemite on September 24th for four nights hiking and camping. I've been dreaming about it all year and it's a pretty expensive trip for me. My prep so far this year has been gear and fitness but I messed up as I didn't fully appreciate the permit system until a few days ago and I've been panicking ever since. Studying the maps and information is mind-boggling with one-way systems and other rules.
Originally I had a rough idea of what I wanted to do - see the busy areas such as the valley and the falls before heading into the wilderness for a couple of days to get away from the crowds. I had even thought about a thru-hike of sorts, exiting at, say, Tioga Pass, and then getting public transport back to the car but I've no idea if that's even feasible.
My buddy and I have done plenty of camping and hiking but the permit thing is new to us and it's too late to cancel flights etc.
Can someone help me salvage this trip?
Can anyone recommend a route that will allow us to see a little of the best of Yosemite over the course of a few days, preferably with some wilderness?
Should we start in Yosemite Valley with the crowds, see some great sights on a day hike and then start the wilderness leg of our hike from somewhere less busy, to get permits?
Am I being over-concerned?
I will be eternally grateful to anyone who can offer some assistance.
