This trail is moderate/difficult aerobic and intermediate with some advanced technical riding. Gridley starts climbing right away and is fairly steep. It briefly intersects a road and continues up through Avacado orchards, please resist the temptation to steal any. It then returns to singletrack goodness and continues to grind up to the Ridge at about 5 miles. When you reach the road at the Ridge turn left and head up to Nordoff Peak for views of the Pacific and Channel Islands. This trail has a couple of forks that are well marked, please stay on the trail and away from the private property. If you are really masochistic you can connect this over to Sisar Canyon for a 30+ mile day. I lost 10 pounds on one ride doing this. Bring lots of water if it is hot out you are exposed and will need it.
From 101 Head North on the 33 towards Ojai. In Ojai the 33 comes to a Y go right onto Hwy 150 and cruise slowly through downtown. Gridley Road will be on the left in a couple of minutes after leaving downtown. Follow Gridley for about 3 miles until it dead ends the TrailHead is here on the left.
