Trailhead

From the junction of U.S. 285 and U.S. 24, south of Buena Vista, drive 5.5 miles south on U.S. 285 and turn right (west) on Chaffee County Road 162 - towards Mt. Princeton. Drive almost 12.5 miles on this road (dirt after 10 miles) to reach the signed Baldwin Gulch Jeep Road on the left (also listed as the 277 Road). If you plan on parking here, there are plenty of pull-offs along the road. This is the lower trailhead. Short, high-clearance 4WD vehicles can drive up the 277 road. Above the river crossing (10,850'), there are dispersed camping spots along the side of the road.

Route Description

Start up the #277 jeep road -  1. Snow often covers sections of this road until early July. It's steep and rough but can be navigated slowly with a high-clearance, short wheelbase, 4WD vehicle. Hike or drive approximately 3 miles to reach a road junction at 10,850' -  2. Turn left onto the #278 road and cross the stream in Baldwin Creek -  3. Continue for nearly 1.5 miles until you reach tree line, then stay on the road as it begins to switchback up Antero's west slopes -  4 and  5.

Follow the road as it zigzags up the west side of Point 13,800' -  6 and  7. Around 12,800', there's a long section ( 8) that ascends southward, leading to the ridge crest near 13,100' -  9. After gaining the ridge, your next objective is to reach the top of Point 13,800'. Continue east along the 278A road -  10. Shortly after departing the ridge crest, keep left at a junction -  11. Proceed another 0.4 miles and stay left at another junction , near 13,200'. Follow the road up the south side of Point 13,800' to arrive at a small saddle on the eastern side of Point 13,800' -  13 and  14.

Pass through an ugly mining area to reach Antero's south ridge -  15. Follow the ridge crest and trail segments along its right side -  16. This stretch offers the most engaging terrain of the route. After the ridge traverse, you'll arrive at a small saddle at 13,850', at the base of the final pitch -  17. Here, you have two options: 1) Follow a braided and eroded trail that traverses to the right and crosses the upper south slope. 2) Hike directly toward the summit by staying near the ridge crest. Most hikers take the 2nd, direct line, given the deterioration of the original traverse trail. Gain the summit and enjoy the views -  19 and  20.
