The majority of routes developed are on the east side, facing Hidden Cracks- getting early morning sun and breeze, and drying first, but the south end- great all day winter bouldering- and west side- shade in mid summer, and the highest lines on the Hilltop- have many awesome problems as well.

Rock quality can vary wildly at the Hilltop.... check your holds before cranking.

To reach Hidden Hilltop- Approach as for Hidden Cracks, but do not make the final hillclimb up out of the stream bed to the right bank. Continue upstream, passing trail to Upper Hidden (large boulder about 30 yds from stream, right side), and stay with the trail until well past Hidden Roofs and the Cave. Look for a scree field, descending from the left (about 50 yards past the stream crossing from right to left bank) and contour up the edge of this, heading slightly left. This will bring you out near the Flying Circus Boulder, with its distinct roof.

Left of this is the North End and the shorter approach to the Front Porch, Pinnacle, and Sphinx. Be aware that this is the sunny side so although this may be shorter, it can also be much, much more vegetated, as well. Greenbriar and assorted wild berries thrive here, as well as poison ivy.

The routes/problems below are listed from the Flying Circus boulder, proceding to the left, clockwise around the Hilltop. This list does not by any means comprise a complete record of established lines.
