Warm Springs Creek descends southwest through Domenigoni Valley for 3 miles (4.8 km), past the site of the former mining settlement of Leon, and runs near the intersection of Leon Road and Scott Road. There, at 1,400 feet (430 m), it descends into a canyon running south-southwest, passing east of the Murrieta Hogbacks, where an unnamed arroyo that drains French Valley to the northeast joins Warm Springs Creek. It continues past the community of Murrieta Hot Springs (a former census-designated place that is now part of the city of Murrieta) on its east bank, running under Murrieta Hot Springs Road. After it passes under Interstate 15, it reaches its confluence with Murrieta Creek in southwestern Murrieta, within the Temecula Valley, at an elevation of 1,033 feet (315 m).[1][2]
