This is an easy route to start with but it gets harder on the way up.
Big Falls is a tall waterfall seen across the community of Forest Falls, California, in the Mill Creek Canyon of the San Bernardino Mountains. It is well known as the tallest waterfall in Southern California, rising more than 6,000 feet above sea level. There is well known hiking trails up the Big Falls, though most trails require lots of difficult scrambling. Though it is a pain to hike up the steep sides, once you get at the top, there is a spectacular view of the mountains of Yucaipa Ridge. It's about an hour in a half hike to the top and to the bottom.
To get there, take the I-10 east until you reach State Hwy 38. Just follow this highway until you junction with Valley of the Falls Drive. Then, take the drive to its end at the Forest Falls community.
I believe there is no Red Tape, but I suggest an Adventure Pass just in case.
Yes camping is allowed, ask the officials just in case.
