I dont know where rattlesnake bar is. I went there by way of willow springs off of 49/20
The national park entrance is off of highway 20, the private side is in cascade shores on the opposite side of the lake accessed thru nevada City
It is off of highway 20.five miles from nevada city heading east
Check Google, it has all the info you need, sorry I wasn't the driver so I'm not sure but its 20 and 49.....
