Peak Summary

As we many of the Sange de Cristo summits access can be an issue due to private property concerns, especially on the east side of the range. See Bushnell Peak for a summary of how to access Twin Sisters from the east or west. Our route description requires an access from the west side of the range, out of the San Luis valley. 4WD with good clearance is required and an overgrown road is utilized that may soon become too obscure to use - at least with a vehicle. Twin Sisters North is sequenced with Bushnell. The overall climb is rated Class 2+ and will involve some extensive boulder talus. Lidar measurements reduced elevation of this summit from 13,012 ft. to 13,009 ft.

      If coming from the south on US285, drive north from Villa Grove .8 mile to a turnoff on the right for County Road 57. Drive north on CR57 1.6 miles to an intersection with a road coming in on the left. This is County Road Nn56.

      If coming from the north over Poncha Pass, drive south from the pass and turn left onto County Road Nn56, which is signed. If you come to Villa Grove, you've missed the turn. Turn around, go back and use the south access. Assuming you find Nn56, drive east .8 mile to the intersection with CR57, then turn left (north).

      From the intersection of Nn56 and CR57, drive north 2.95 miles. The nicely graded gravel road will soon make a 90 degree turn east, then another back to the north. Continue north until you come to an intersection where you must go left or right. Turn right and immediately come to another intersection where you bear right. Shortly, the poorer quality road will come to another intersection where you should stay left. Proceed NE following alongside a small stream - Raspberry Creek, which is not very visible, and some obvious campsites in the cottonwoods on your right. At these coordinates, (N 38° 19' 26.67" W 105° 56' 48.76") turn right onto a single track road that will cross the creek and lead to a fence & gate. Go on through the gate & close behind you. If you miss this turn, you'll end up at a home with No Trespassing signs.

      Once through the gate, you'll intersect another road coming in from the right. You should arrive at these coordinates: N 38° 19' 23.52' W 105° 56' 44.72". If that checks out, you're on the right path which is FS985. It will now be another 1.7 miles to the trailhead on a very rocky, slow-going, barely visible at times track that passes through patches of scrub oak that will scratch up your vehicle. You may be better off walking considering how slowly you must take a vehicle through here. The USGS map indicates two roads heading to the same location. The northernmost of the two is in disuse and barely visible. Stay on the more southern track. Later on, the two come back together, but there's really only one track here that's usable. We drove this in 2005, then again in 2017. The Forest Service has not necessarily closed the road, but appears to be doing nothing to maintain it. The local resident with the property says the FS has closed it, so don't expect this access to become any easier over time.

      The road ends at these coordinates (N 38° 19' 40.15" W 105° 55' 48.04") which is marked on the USGS map as an elevation point of 9,143. If you don't have a vehicle capable of making these last 1.7 miles, then we would suggest trying to park and camp back along Raspberry Creek where there are some camp spots, and walking up what we hesitate to even call a road. We will warn you again - this road is very rough. If you don't have a 4WD with good to above average clearance, we would not suggest attempting to drive up. Also, your paint job will not be the same.


      There's a little bit of some level area where vehicles can be parked and a tent set up at the trailhead coordinates. Brook Creek can be easily reached for water supply by hiking south 100 yards through the trees.

      From the Brook Creek Trailhead, continue walking east up the old roadbed. The berm that use to be here in 2005 has degraded some and it's possible to drive on up a short distance to another campsite on the left in the trees, but you won't be driving much further. Fallen trees across the road will soon block vehicle progress. The road begins with just modest gain and passes an old log cabin. Once past the cabin, the road takes a steeper angle. The road crosses to the south side of a north fork of Brook Creek, then later on crosses back to the north side and about 100 yards later crosses back to the south side. Once you're done with all this stream crossing, the road begins a series of switchbacks (about 9 or 10) to gain altitude. Following the old road is never difficult, at least at this time, but limited access to this valley will eventually lead to overgrowth on the road. (Our last visit here was in 2017.) The higher you hike, the more the road shows signs of disuse. Watch for some nice displays of Columbine along the way.

      Above the switchbacks, the road begins to break out of the trees. At about 10,600 ft., choose a place to begin ascending right up along the edge of the trees to the WSW ridge of Bushnell. There will be a lot of old, cut trunks. 800 feet of relentless elevation gain should bring you to the ridge. Turn left (east) and hike along the mostly tundra/grass ridge crest and open forest to the last trees at 12,100 ft. From those last trees, it's another 1,000 feet of gain on a combination of embedded rock, rock & boulder talus, some areas of tundra, etc. As you near the summit, you may want to veer from the ridge a little to the right (south) because of the rock. In 2005, it took us about 4 hours from the trailhead to gain this summit. Enjoy the views of the east side of the range where the activity of ancient glaciers is quite obvious. Once you've concluded your summit visit, it makes good sense if weather permits to hike on north to Twin Sister, which we have sequenced with Bushnell.

    Route Description

    Year Climbed: 2005

    The route to Twin Sisters North begins at the summit of Bushnell Peak, so is sequenced with that summit. Refer to Bushnell for the approach.

    From the summit of Bushnell, begin the journey over to Twin Sisters. The route north follows along the spine of the range. It requires that you hike over the summit of 12,730 ft., (Twin Sisters South) while continuing north for more than a mile. The initial descent off Bushnell is a little tricky with large boulders to negotiate and some very interesting rocks to examine. Head on over the 12,730 point. Trying to contour on the west side will save little if any time because of the boulder talus. Once past the 12,730 summit, it's mostly a slow stroll along the ridge to the summit of Twin Sister North with mostly embedded rocks and some boulders. Northeast of the 13,012 summit and about ¾ mile away is a summit that appears to be equally high, but maps indicated it is only 12,984. You may want to consider going on to it if time allows because it is a high ranking twelver. The route over is no more than Class 2+.

    To descend, backtrack south along the main ridge and a little below 12,800 feet, drop west and head down the open slope. The descent is very steep and rocky being largely comprised of medium to large-sized, often teetering boulders. Every now and then, you may stumble across a brief area of tundra and dirt or smaller scree. If you look closely at the USGS map, it shows a small area of trees between 11,600 and 11,800 feet, and located between two minor drainages. Head toward them. They will be your first relief from the tedious descent, and even then, the terrain is still quite steep descending through the scattered trees. Among these trees we found an abundance of Jacob's Ladder, (Polemonium pulcherrimum delicatum). Work your way on down to the southernmost of the two drainages, cross over and you may pick up a trail of sorts. Keep heading down WSW and you should pickup the remains of the old road a little below 11,000 ft. Four switchbacks down the road and it will head SW for a longer stretch where you should intersect the place where you departed to head up for Bushnell. From that point, it's just a long hike out on the old roadbed back to the trailhead. This descent route may also be used as an ascent route if you choose to do Twin Sisters North alone or do this entire route in reverse.
