lashburn1, yes, it is actually San Bernadino Regional Park - Park Moabi. They have had a difficult time running it profitably over the years from what I've been told and the partnership with the commercial enterprise that is Pirates Cove has turned out to be pretty successful. There used to be an extensive ATV trail system (160 acres) that was taken out of service or was perpetually in repair, not sure which. And since you said you had your Ranger there with no issues, I'm considering bringing our RZR4.
Those shots are great! Was it hard getting a reservation? It doesn't look too good for us getting an entire peninsula since we waited so long.
I think we are leaning towards August for the big RV expedition to the river. We usually stay up the road in Needles at the Marina, they have hook-ups and slips, but the facility is old and the ramp is in disrepair because they would have to shell out some big bucks and get Coastal commission permits to repair it.
One way or another, we'll make it out there this summer....I hope!
