I park beside the highway and leave a note stating I’m paddling the river. We leave a vehicle on highway 74 in cimmaron city. The road you turn in to park at the beginning will take you east all the way to 74 where you drop off vehicles and end up at after paddling. It’s a decent walk up to where you park and put in. Make sure there is water from good rains or you will walk here and there. Most of the time it is roughly 2.5’-4’ deep. We have done this trip in one day but I do not recommend it. Make it an over night even a three day camping adventure and you will really enjoy it. Plenty of beaches to camp on. Very rural and you will rarely see anyone else on the water.
