Peak Summary

Note: At one time, some may have identified this as "North Carbonate." Cronin is named after Mary Cronin, who is reportedly the first woman to have climbed all of Colorado's 14ers, having completed that task in 1934. She was also only the 4th person known to have done so. The current name was approved by the USGS in 2005, so you will find very few maps that acknowledge it.

Cronin Peak is a nickname for UN 13,872, per LIDAR, (formerly UN 13,870/North Carbonate), a Class 2 summit which lies WSW of the 14er - Mt. Antero. This summit is easily accessible by way of its ESE ridge if you have a vehicle capable of making it up FR278 which is the road up Mt. Antero. That tedious road is best tackled with a shorter-bed, higher clearance 4WD vehicle. You can park around 12,700 feet to begin the hike. For those who either want to make the hike more sporting or who don't want to abuse their vehicle on FR278, another alternative is to drive the three miles from the lower, Baldwin Creek trailhead to the FR277/FR278 junction, park and hike the NNE ridge of Cronin, which still has a Class 2 rating, but is rockier. Either way requires a higher clearance vehicle at a minimum. It's also possible to walk from the Baldwin Creek lower TH, but this will add six miles round-trip to the day.

RT From Baldwin Creek: 6.6mi / 3,000'
  • Trailhead
    • Baldwin Creek TH

      From the center of town in Buena Vista at the US285 and CR306 intersection, drive south 8.1 miles south on US285 and turn right onto CR162. If coming from Johnson's Corner, drive south 5.7 miles to CR162. This is also known as "Chalk Creek Drive" and heads up towards the Mt. Princeton Hot Springs and takes you below the spectacular Mt. Princeton Chalk cliffs. Drive west on this road for 12.5 miles to the townsite of Alpine. Or measure from the end of the pavement 2.0 miles. Across from Alpine Reservoir is the turnoff for FR277 that heads up Baldwin Creek. There is very limited parking here. You may be able to find some parking around Alpine, but most everything is private property, so be careful where you park. Summer of 2019, we noticed a lot of vehicles parked along the road both before & after the trailhead.

      It is possible to drive up the Baldwin Creek road if you have 4WD or 2WD with very good clearance. Every time we've been on this road (and that's quite a few), we have found it tediously rocky and slow and with more and more 4WD's, ATV's, etc., it is not likely to improve. We were last here summer of 2019 and took a quick look at the road condition. Personally - we would not advise going up this road any longer unless you have 4WD with excellent clearance. That said, we did notice signs indicating that some actual work (road repair) was going on, so perhaps there will be some improvements. This trailhead will be somewhat unique in having an "Upper Trailhead" as well. This is where FR277 and FR278 split with FR278 heading off to the left (SE) and immediately crossing Baldwin Creek. FR278 heads up onto Mt. Antero and eventually crosses over into Browns Creek. FR277 continues SW up along Baldwin Creek to a switchback where a trail to Baldwin Lake heads off. Trails Illustrated shows the road ending there now as does the Forest Service map. The coordinates for the FR277/FR278 intersection are N 38° 40' 57.11 W 106° 16' 22.56". Elevation there is 10,870 ft. The distance from the lower TH is 3.0 miles.


      At-large camping opportunities along CR162 are very limited, mainly because of all the private property. There are National Forest, fee-based campgrounds along the way. They are: "Boot Leg" at 8,400ft. with 6 units & no water; Mt. Princeton at 8,000 ft. with 17 units; Chalk Lake at 8,700 ft. with 21 units and past the Baldwin Creek road and up toward St. Elmo, the Iron City CG at 9,900 ft. You can expect all of these to fill up on weekends. This road leading up to St. Elmo is a popular weekend destination for all types of recreationists.

      Near the FR277/FR278 intersection, there are some limited, primitive camping opportunities. Drive just a short distance farther on FR277 toward Baldwin Lake and there is a good area with multiple campsites at the coordinates provided below. There are also some good primitive sites on FR278 just after crossing Baldwin Creek.

      Elevation 9,900 ft. Turnoff is along the short stretch of road that leads down to St. Elmo. This campground has 15 sites, one vault toilet and an untreated water pump that we could not get to work.

    Route Info Cronin Peak North Ridge

    Route Description

    A popular route for Cronin has been to access the prominent north ridge of the peak. This is a route we have not done ourselves, but we are posting some material here that may be of some help to those trying to reach Cronin, but do not wish to push their vehicle beyond the intersection of FR277 and FR278. The following therefore, has not been field tested, but follows similar route descriptions including the old G&M. If walking this route all the way from the lower trailhead to Baldwin Gulch/Creek, add 6 more miles round trip and another 1,420 feet of elevation gain.

    From the previously mentioned intersection, drive across Baldwin Creek, locate a parking spot, then begin walking up FR278. Walk all the way to 12,000 ft. and the last trees. There's an open area here and some primitive campsites. Coordinates are: N 38° 40' 00.34" W 106° 15' 46.29". From here, cut almost due west through the forest, aiming for these coordinates: N 38° 40' 01.22" W 106° 16' 07.57". This should bring you out on the edge of a small clearing overlooking the east fork of Baldwin Creek. You will lose about 300 feet in elevation to reach this point, but you will have minimal conflict with the willows. Find the shortest route you ca across the creek and through the willows aiming for the edge of some trees. Once you reach the edge of the trees, hike just inside the forest, away from the willows and head SSW up the drainage a short distance. You will come to a minor tributary to Baldwin Creek. Head more westerly above this tributary on grassier, tundra slopes, gaining elevation west to the last trees. Once above the trees, turn and hike more to the south on a gently sloping tundra bench. Towards the end of the bench, turn more SW to intersect a minor ridge that runs from SW to NE off the main north ridge. This ridge begins still in tundra but changes over to talus/rubble. Follow it all the way to the north ridge of Cronin which you should intersect at 13,400 feet at these coordinates: N 38° 39' 34.10" W 106° 16' 53.71". Follow the remaining rocky north ridge south to the Cronin summit. Because of the rock conditions, this is more difficult Class 2 hiking.

    We hope this helps. If anyone utilizes this and finds significant problems with our description or coordinates, please notify us.
