A long and steady grind up Mt. Wilson.

Features -none-

Family Friendly Wide easy trail with minimal exposure. It is a bit steep so does require low gearing and/or strong legs.

Description

This is a long fire road climb up to the top of Mt. Wilson. It just keeps going and going. The grade is pretty consistently around 10%. From the bottom up to Henninger Flats is about 2.5 miles of wide open fire road with no shade. When you reach Henninger Flats, you'll find some large trees, picnic tables, a water fountain, and the Henninger Flats Museum.

As you continue up, you'll find a split in the fire road. Keep right and climb. Near the top, you'll find a bit more shade in spots. The view is fantastic on a clear day as you come around to the south side of the ridge and climb the final section to the top.

At about 7.5 miles, you'll intersect with the Mt. Wilson Trail. Keep left and rejoin onto the Mt. Wilson Toll Road in about 0.5 mile.

There is a great lookout at the top. Be sure to check out the Mt. Wilson Observatory if you have time.

This is a long brutal suffer-fest as the climb just doesn't let up. Leave early in the summer or you'll cook as there is a lot of exposure down low and higher. I made the mistake of riding my old hardtail with 1.75 street/hardpack tires and there is a moderate amount of loose rock and sand up higher. Use a good trail bike on this. There are some nice views along the way though. Jul 29, 2018
