Hidden Spring Canyon

For what it's worth, the drive to Twin Point took just under 4 hours from Smith's supermarket/gas station at the I-15/Southern Parkway junction. The car computer (Grand Cherokee 4WD) said we used 4.54 gallons of fuel to get there i.e. 9.1 gallons return, BUT, please have a full tank of gas just in case. The distance to Twin Point was 89.5 miles from the Utah/Arizona border where the dirt road begins.
