Take Highway 101 to Santa Barbara and exit on 10th Street/Hwy 154. Drive East on Hwy 154 over the mountain. A few miles after crossing the San Marcos Pass you will come to Paradise Road. Turn onto it heading East, it's the only choice. Drive until you get to the end of Paradise Road. You will be able to see some jumps from the road but if you want to see the big jumps follow the Red Rock trailhead at the very last parking lot. There are many, many jumping holes around here so enjoy and don't make the rangers drag your corpse out of my jumping pool.
