Will be up there floating and fishing from the 18-21st. This is the second year I've been on this stretch.
Here is a good site to view the camps on the river Snake River - Palisade Dam to Lorenzo (South Fork) - River Brain
You can definitely pull off and car camp
Last time we floated the canyon in 3 days 2 nights but we put on late the first day. It can definitely be done in 2 days but I guess it also depends on how many fish you catch and how much you row. Also floated the top section from the dam down. All sections fish great.
I believe fulmer is a place where you can camp with the car
