Sobo is another rare "wilderness setting" within Eldorado canyon. There is a string of summits extending from Rincon to the north/north west, including Cadillac Crag, The Veil, Physical Crag (and Split Block), Diamond Head, and Sobo, which is the most remote and probably the least visited of these. My partner left a pair of sunglasses at the base of a route there in July of 1996. I picked them up in February of 2002. The most recent printed guide listed only 3 routes at Sobo, although there are now at least 6, with potential for a few more, particularly if someone want to do a few hair-raisers. Top-roping at Sobo would be difficult. 3 of the 6 known climbs are stellar crack single-pitches, and would have climbers cued up like Calypso if they were close to the road; they are worthy of a hike in for a day of climbing. Much like the other crags in this summit chain, it does not see much traffic, even on holiday weekends. The setting is a nice, and may be the best place to go if you fear crowds in Eldo.
From the Eldorado Canyon Train, starting as for Rincon or Cadilac crag, passing the Rincon cut-off. Continue on the trail until you are directly below Diamond Head, then scramble uphill over talus to reach the base of Diamond Head, then traverse West to Sobo. This should take about 60-90 minutes. There are some sections of marked trail (cairns) down from Diamond Head, but even from the top down, these can be difficult to follow, and you may end up just wandering down the hill. Although there is not much of a trail, the hike is much longer than it is difficult, if you make it a point to avoid any thickets.

Dreams Of Light 5.10a CO : Eldorado Canyon SP : Sobo
Once you reach Sobo, the Southwest facing prow is obvious. Dreams Of Light is a nice and [varied] crack and left-facing dihedral system that ascends from the left side of the prow. Climb up the broken dihedral past a few "trimmed" shrubs to a squeeze chimney. Go up a [squeeze] chimney for 10' to a seat on the arete to the left side. This is a great rest. From the seat, move up a few moves and look left. A hand-to fist crack diagonals up and left through the overhang/roof (3.5 camalot, then @...[more] Browse More Classics in CO
