Had a bit of trouble finding Oak Grove Ranger Station; Google Maps has the address wrong by about a mile.
Once on the trail, it's a nice climb up to the fire road. From there a pretty boring but consistently uphill road walk. The views are superb though! Baldy, San Gorgonio, San Jacinto, Santa Rosa. From the summit could even make out the buildings in downtown San Diego and Point Loma through the haze. Tower was actively staffed with an observer.
This would be a fun mountain to do on a gravel bike.
