The Onion Creek Road also branches east from Highway 128 just west of the Fisher Towers Road and beween mile markers 20 and 21. The Onion Creek Road is one of the most facinating drives in the world and can be rough in places. The road crosses he creek many times, but in good weather, most cars can be driven to the trailhead if you drive slow. Drive up Onion Creek through the narrow canyon section with many towers. Park at the first major canyon coming in from the north. The trailhead is not marked in any way, nor is there a real trail here.
These are the "C" ascent and descent approach routes to the Fisher Towers.
The C-1 approach is a really fun approach to the towers. The route is mostly class two to four, but has a few 5th class pitches throw in for excitement. The most difficult move is a 5.8 chockstone move. No bolts are in place and none are required by competent climbers as the 5th-class pitches are all short. Those who don't want to climb the towers will find any of the C approaches to be exciting enough!
From the Onion Creek Trailhead, scramble down into the drainage. Follow the canyon north for .75 miles to a junction. The left canyon is C-1. Follow the drainage up C-1. The first right-hand canyon is C-2. Continue left along C-1. Stay in the main drainage. There are two more side drainages, one to the left and one to the right. After passing all the fun obstacles, you will reach the Fisher Towers bench which you can follow west to the Titan, Ancient Art, and Echo Tower, or east to Oracle, Hydra, Pillars of Hercules, Doric Column, Citadel, Mystery Towers, Doric Nightmare, and Atlas. Sometimes the bench is narrow, but it is passible all the way to the Fisher Towers Trail on the west to Atlas on the east. The section of the bench near Doric Tower and at the head of C-4 is very slow going. C-2, 3, and 4 can be used as descent routes if following the bench east.
A 100 foot (30 meters) climbing rope, harness, and a full rack will be more than enough.
If you have information about this route that doesn't pertain to any of the other sections, please add it here.
