Really a nice way to ascend to half-way point up Mt Diablo but be prepared to sweat:-) There are some very nice views down through Blackhawk/San Ramon. The trail-side scenery is great too, some really interesting rock formations. This is a pretty tough trail in terms of steep inclines, but it's a fire road not single track so it's all relative, ie-if you have to stop and walk the bike up a particularly tough grade you're not going to fall off your bike and tumble down the mountain doing so. I rank it advanced for the hills.
Briones to Mt Diablo trail becomes Wall Point so you can access this trail via Shell Ridge or from Castle Rock via Portugee Gap. I've not come up the half-mile link to Wall Point from Pine Canyon (Castle Rock) only gone down it a number of times. Given that experience I wouldn't recommend riding up Wall Point from Pine Canyon it appears just too steep and rocky for most mortals. Also, everytime I ride Pine Canyon it's three or more lectures from the horse people and I'm a pretty darn considerate rider re: horses...it's just not worth it to ride that trail for me anymore, too many horses and their owners. When I ride, I'm trying to forget traffic and people not find a whole new breed of self-important Californians...
Summary: This is the grind climb in Mt Diablo and makes a good loop when joining in from Shell Ridge and Diablo Foothills regional trails.
It's open and exposed to wind and the sun....so plan accordingly. None of the trail is impassable and there are some level portions for limited reprieve and flushing the lactic pain in the legs with a spin off. Great views from both sides of the trail. This will plug you into pther trails to summit Mt Diablo.
As usual, small amounts of precip can impact the conditions, and the clay powder turns to flinging cake mix without much moisture.
Recommended Route: If coming from Shell Ridge, you can meander and get along the Briones-Mt Diablo trail and it will butt into Wall Point. Almost at the top of Wall Pt there is a single track (marked no bikes)which is usually in very good condition, which will traverse the slope and connect with BBQ Terrace, for a descent into Pine Canyon and the numerous stream crossings. There's nothing too technical on teh up or down, but keep your speed controlled and pick the right lines coming down. I've seen plenty of people that have let the descent get away from them and pay some consequences.
Other recommended trails in the same area: There is a trail that runs atop the Castle Rock Ridge line (there's caves to explore, great views, Raptors doing their thing and hoots and hollering from the rock climbers)...can be accessed from trails off of Burma Trail up from Pine Pond and past the connect with Sunset Trail. It's technical, tight and fun, but will warrant a couple of fence crossings, true x country w/o trail on private land and riding in and along a stream to connect back to shell ridge loop trail near the large concrete wash out.
Bring your camera, cliff shots and water.

Summary: I'm living down off stewart right now and I couldn't be happier. Park at the base of rudgear/stewart then flow up the singletrack to sugarloaf tr. Make a left at the 4 way and cruise down to twin lake. Now its time to get to work. Briones-mt d fire trail through a few gates until you reach a rutted out hill. Test your balance or go a little further down the trail, theres an easier assent that isn't so rutted. Now your on Wall, which will eventually lead you to Rock city. Ride the paved for a little bit until you pass the first camp area then jump on the trail again. You'll cross the road at one point by the dirt piles. You can make the choice of climbing the small bit of trail in front of you, or just taking the road as Pine canyon is just to your left up the hill a bit. Choice: hit Pine canyon, which will loop you back home, or continue up Summit trail enroute to juniper and burma. For the topic of this conversation, we'll go down pine and come down to Castle rock. Forge the crossings if they are flowing then make your way up to broges, back to twin ponds and your car. I recommend going during a week day to avoid any crowds and when it's not to hot helps too. The breeze on the mountain is great but the valleys swelter during the summer, and there isn't a lot of shade on pine, so i'd recommend riding up Wall and going down pine. Try this loop, plus summit tr. to the top, then do costanoan out of broges. If your legs aren't jello after that then you can pretty much go anywhere. For the ultimate ride, include mitchell canyon to burma, then side track to mothers (legal baby) back onto burma then to pine. At this point you can pat yourself on the back for riding just about every trail on the west side of the park. Get a map at any bike store before you go. 3 rubbers for variety, view, and overall ass punishing ability.
Recommended Route: any way's a good way

Summary: The only possible slam on Wall Pt. is the fact that it is a fire road. Other than that, it is steep (in places)and challenging, beautiful views and territory, full of wildlife (deer, bobcat, coyote mostly)and gets you to mid Mt. Diablo, where a number of other options open up. Wall Pt. is also a really fun descent off of Diablo, with speed limited only by your skill. As the first post mentioned, while the climbs may be a little better for fit riders, anyone can take advantage of this trail. I'm giving it 5 fatties, just because I've had so many good rides which have included Wall Pt.
Recommended Route: Wall Pt. can be accessed as previously described (and the ride up from Pine Canyon is not really too tough) or from the Macedo Ranch staging area at the end of Green Valley Rd. Wall Pt. can be part of various loops, or done as an out and back. One of our common loops is to ride up Wall Pt., take Summit Trail (immediate left at end of Wall Pt.) to BBQ Terrace, drop down BBQ to Pine Canyon, ride the canyon down to Borges ranch, cut down to Twin Ponds loop then back to Briones-Mt. Diablo. I'm not sure of the distance, but it is about a 2 hour ride. Another alternative is to poach the single track 3/4 of the way up Wall Pt., which drops you to mid-BBQ Terrace. There are a number of other possibilities, including doing a full, summit loop with some single track thrown in...be prepared to ride most of the day.
Other recommended trails in the same area: There's a bunch, get a map and have fun.
