Three Forks can be reached by taking the Three Forks road south from Highway 95.  The turn off onto this road from 95 is 17 miles to the east of where 95 crosses the Owyhee.  The Three Forks road is mellow except for the last mile or so where it drops from the canyon rim to the river.  This is a steep switch-backed area that requires 4-wheel drive and high clearance.  Pulling a trailer could be tricky on this last section of road.
