While not awe-inspiring, The Sacred Cliffs comprise numerous sandstone blocks and buttresses that form the North-South ridge line of Green Mountain. The rock climbs a lot like Eldorado or Mickey Mouse. Over the last decade close to 50 routes have been installed, without coming close to tapping the full potential of the area. These span the gamut from full trad to fully bolt protected.
Most routes are short, with the longer ones running 100 feet and many topping out after 40 to 50 feet, however, at least one two pitch route was established, and it is 140 feet overall. Difficulty largely runs into double digits, although some fine routes can be found at 5.9 or easier. Nearly all of the routes face due West and get great sun from noon until sunset. First ascent data is difficult to come by. I was introduced to the area by Joe Desimone more than ten years ago, and he has established many of the better lines on The Sacred Cliffs. Greg Hand and Ray Snead put up some of routes about the time Joe was doing so. Other contributors will be identified as is possible.
Numbering of rocks and routes begins from the North end of the hill with Name Game Rock and route #1, Close to The Edge. The approach via the Green Mountain West Ridge Trail is moderate, gaining only 200 to 300 vertical feet, and takes not longer than 20 minutes from the car.
The best approach to The Sacred Cliffs is from the West. Take Base Line road out of Boulder for several miles until just before the West plateau, approximately one mile West of the Green Mountain summit ridge. Parking can be had on the roadside near a rough four-wheel road that runs into the housing. Follow this road East, passing several houses, until a poorly marked trail departs due East. Take the trail, The Green Mountain West Ridge Trail, for 3/4 mile. This will deposit you at the North end of the mountain near the true summit (8144ft). Climbing begins several yards South of the summit.

This is a pleasant climb on the upper half and potentially pleasant on the lower half, depending on the route taken. Choose wisely for the best rock. The second pitch is a mellow romp with a spectacular position.P1: start at the base, just North of the obvious summit block of the South Peak of Green Mt. (AKA: Main Crag of the Sacred Cliffs). Climb up perhaps 25 meters, picking a line with the easiest moves and best stone. It is perhaps 5.4. Arrive at a good ledge near a notch to the East Fa...[more] Browse More Classics in CO

Is THAT why they called it the sacred cliffs?

This cliff band is out there, and I'm not sure if it's worth the hike. There is no real trail so be prepared to walk through downed branches, loose dirt, and lots of pine needles. That being said, if you are climbing in Boulder on a Saturday, this rock may be a good option to avoid the crowds. Though there will be a lot of people on the trail to the top of Green Mountain. Great views and worth exploring if you have climbed a lot in Boulder and are looking for something new. The book says about a 40 minute hike, but I would prepare for an hour, since you have to pick and choose your path.
