Quickie Report...
Anza-Borrego Desert State Park is located an hour and half east of Escondido CA, northeast of San Diego CA. This is primarily desert environment, though the drive in on 78 is rural coastal California traveling through the communities of Romana and Julian. Great Apple Pie seems to be the popular food item in the area and thats where we met our trail guides for the day - at Dudley's Bakery in San Ysabel.
Touareg participants included Arkarch (myself) and VegasMatt. Another of our radio group MattM came out with his Jeep Rubicon 2003. I followed up on an offer with FJ'er Ollie from OutdoorAdventureUSA who led the group. His tailgunner was FJ'er Frogeye. Both are veterans of the Ouray FJ Summit and Moab events, and run the San Diego trail network most every weekend.
Once in the park area, we took Oriflame Canyon to get on the dirt fast and bypass a section of Highway 78. This trail is mostly hilly dirt road on the front end, winding into a shelf road with a couple switchbacks and rock holes to navigate through. Its a good trail, kinda like Colorado's Corkscrew through a rural Southern California setting.
We then traveled past a few other communities to make our way to Arroyo Seco Del Diablo, a canyon gated by a very sandy Diablo Drop-off.
The approach was mostly driving through wide (100') canyons, breaking into a wide bowl. Then dropped into Vallecito Canyon before heading into Arroyo Seca Del Diablo proper.
We made a pass through a slightly challenging notch, then back into the flat before reaching the vista of Diablo Drop-off. The drop-off is pretty much one way - its a very sandy stepped descent down a steep slope. Once down, it is unlikely without a very custom rig to climb up out of this sand trap; our Rubicon friend was barely able to make progress on the way back up and eventually needed to be winched out by our FJ lead. Most of us waited until VegasMatt and Ollie confirmed their was a viable way out with the Touaregs.
With the green flag, we took the Diablo Drop-off, which includes several tiers down into a lower canyon. Then we reached a 200' section of rock garden to bring the Touaregs through. With the steel and 32" tires, we still could have used a bit more clearance - our break-overs required rock stacking in places. An Air Suspension'd Touareg with 32" tires should be able to work this with reasonable spotting. We made it too!
The major obastacle in Diablo was as intense as one can get running a Tourareg over a boulder trail. Yes we were bumping out bottom, draggin over the rockers and pivoting on mounts. In short, we exercised every spec on the vehicle - approach, departure, breakover - dealing with both rock gardens and fine sand throughout. While we dont have Jeeps, Touaregs can make these big trails - so long as you are patient and have fine spotters and guides to keep you out of trouble.
Right behind us, a driver of a stock 4Runner pretty much destroyed is running rails working through the rock garden, then fully high centered on the final boulder. The sound of rock and metal by this guy... ouch!
Once out of Diablo, we travelled through flat Fish Creek Canyon, then to Split Mountain for the group shot, and then emptied out back to the highway for a bit of air-up.
We'll be out there again.... Fonts Point awaits, as well as Sandstone and Coyote Creek.
