There's a dirt road on the right, immediately
before the parking lot, it follows a wire
fence.
Follow it upriver (I think it's cool to do so
as
there are no signs stating otherwise) to a good
parking spot for the wave.  It saves alot of
walking from the asphalt parking lot.
   Dave how the heck are you and where have you
been??? you better take a second look becouse
there is a sign at the start of the road.. it
reads no trespassing Inland Empire paper. but be
carefull of the parking, my van was broke into on 
wednesday and another kayakers rig on monday at
sullivan hole, put all valuables out of site!!!!
