Are trails to the Berry Creek Falls in Big Basin open now?
Have you seen the cataracts at "Little Yosemite" in Sunol? That is spectacular when Alameda Creek is full. The last time I hiked there when the water was raging I got clobbered by a hail storm at the falls. That was the year the young woman lost her life when her care was swept into the creek.
Alum Rock Park has a lot of waterfalls, too. Alum Rock Park waterfalls
No, I have no idea when that will be open. I think the only part of Big Basin that's open is the Waddell Creek parking lot and part of the trail around the marsh there. Maybe a mile or so at most, I'm guessing.
