Stay on the stream bed cobblestone... stay off the sandstone. Not much fun..... extra slick. PT. Dune in Malibu, at the beach works.... or better yet.... grab some Granite, but that’s a bigger drive.
Just so you know, it’s bern raining here in Ojai all night and morning. It wasn’t a light rain. Rock will still be wet on Saturday. The water collects in all the earth above the climbs and seeps through the cobblestone cracks for quite awhile after rain. Sandstone wall will be wet still also.
