Tub Springs Road is a rocky dirt road that offers amazing views of Lower Owyhee River Canyon. The spur towards the trail's southern end is the best part; it's a rocky road that'll take you to an epic view of a horseshoe-shaped bend in the Owyhee River.
This is mostly easy to navigate, but there are occasional steep rocky hills to climb, so 4WD is nice to have but not necessary. However, high clearance is a must for this trek.
Tub Springs Road intersects Kiger Road in the south, which will take you to the Pillars of Rome, a cool rock formation worth checking out. It intersects Rinehart Ranch Road in the north.
