Trail shared by Matt Giaraffa

A big loop on Mt Antero, from Mt Princeton Hot Springs, with an epic descent down Little Browns Creek Trail #1430

Features -none-


The climb from Mt. Princeton Hot Springs all the way up to 13,100' on Mt. Antero is tough, but can be shuttled in a high clearance 4x4 vehicle. This gives options depending on your climbing strength. However you get to the top, the descent will be steep and not beginner friendly.

Need to Know

Start early, as you are above tree line for awhile. Storms can develop quickly in this area.


Start from the Mt. Princeton Hot Springs parking lot and pedal up County Road 162 (Chalk Creek Dr.) just past the entrance for the small town of Alpine. Look for small parking areas for OHV use, and Baldwin Creek Road #277 on the left.

Head up that 4x4 road and continue on until it forks with Mt. Antero-Browns Lake Road #278, cross the creek and continue up FS278. On the other side of the creek, it gets steeper and rougher until you get to the switchbacks going up to the peak of Mt. Antero. Then, it stays steep, but smooths out. Continue up to 13,100' and look for the saddle between the peaks of Mt. Antero and Mt. White. That's where Little Browns Creek Trail #1430 starts.

Descend Little Browns Creek Trail #1430, and when it merges with the CT - Segment 14: Highway 50 to Chalk Creek TH, you probably won't notice because the rate of butt-hauling is elevated at that point, but continue on the Colorado Trail. Eventually, there are two ridge climbs before dropping down a steep descent back to County Road 162 (Chalk Creek Dr.), where you turn right and cruise down the road back to Mt Princeton Hot Springs.

Make peace with your gods before the Baldwin Creek climb. The tech and continuous descent on Little Browns is worth it. 28mi — 4h 00m

Challenging climb with some grueling hike-a-bike. Awesome techy decent on Little Browns Creek Trail #1430

Finding the beginning of the Little Brown's Singletrack can be tough. This is what you're looking for.
