In reply to Jack the gripper: Hi Jack
Bishop is situated on the inland side of the sierra mountains that run up the west coast of the US. If you find Yosemite on a map and follow the road over the range you get to mammoth lakes, it is about 50 miles south of there. I got there by hiring a car from LA and driving there, fairly easy drive.
I have also hired a car in merced, the main town near Yosemite and driven the car over toulome meadows. It is a great venue. Boulder all day then drive to a hot spring at night, before retreating to the free campsite (This was a few years ago now but I am sure someone here knows if it is still free). The campsite is like the moon - cold, barren and featureless!
Only spoent a few days there we went to the happy boulders, and the peabody boulders. One was sharp granite the other basalt? Lots of highball problems, like grit routes. See/Ask Mick Ryan's profile pic of the highball bouldering.
There is a great coffee shop and a very relaxed vibe when we were there off season. Just book your tickets and go!
