9/1/2019: Bautista road is fully closed between the conservation camp and the Anza area. Talking to a couple rangers, they have not been able to repair flood damage because they have been concentrating efforts and budgets on the main highways through the mountain after the recent fires and floods. A section of the 243 is totally closed at the moment between Pine Cove and Banning, and the 74 coming in from Hemet is only available by escort to Mountain Center. It's still a big mess up there! They mentioned there are some rugged hiking trails that may get you to the claim from the north, but it was 105F outside and a hike like that was not going to happen. I did a little more research upon return and found the Riverside County sites do show it (as well as other roads in the area) as closed.
