This route was planned by komoot.
The Mount Antero Trail is considered a demanding and strenuous hike, often rated as Class 2 due to scrambling sections. Hikers should be prepared for significant mileage and elevation gain, especially if starting from lower trailheads. The final push to the 14,269-foot summit involves a Class 2 scramble over dirt and rock, including talus fields and scree, which is the most difficult part.
The full hike from the lower Baldwin Gulch trailhead typically ranges from 14 to 16 miles round-trip, with total elevation gains of 5,200 to 5,416 feet. While komoot estimates a duration of approximately 5 hours for the featured route, a full ascent from the lower trailhead can take 8-12 hours or more, depending on your pace and starting point.
There are two main approaches: the West Slopes route from Baldwin Gulch and the Browns Creek Trail from the east. Parking is available at these trailheads. For those with a high-clearance 4WD vehicle, the initial segment of the hike can be shortened significantly, as the road extends to nearly 13,800 feet, leaving a shorter scramble to the summit.
The terrain varies considerably. It begins by winding through vibrant aspen groves and lodgepole pine forests before transitioning into lush alpine meadows. As you ascend, you'll encounter more exposed tundra and rocky, rugged sections. A significant portion follows an old mining road, shared with 4x4 vehicles, featuring steep switchbacks. The final ascent involves a Class 2 scramble over talus fields and scree.
Mount Antero is one of Colorado's 58 fourteeners, standing at 14,269 feet. It boasts one of the highest roads in the United States, allowing 4x4 access close to the summit. Perhaps its most unique feature is its rich geological makeup; it holds the highest gem field in the contiguous United States, with significant concentrations of aquamarine. Active mining claims are still present on the mountain.
Yes, the Mount Antero Trail is generally considered dog-friendly. However, given the strenuous nature, high altitude, and rocky terrain, ensure your dog is conditioned for such a hike. Always keep your dog on a leash and pack out all waste to protect the delicate alpine environment.
Mount Antero is located within the San Isabel National Forest. Generally, there are no permits required for day hiking or entrance fees for accessing the trail itself. However, always check the latest regulations from the US Forest Service for any updates, especially if planning overnight stays or specific activities.
The best time to hike is typically from late June through September, once most of the snow has melted and before winter conditions set in. Wildflowers are abundant, especially above the treeline in July. Be aware that snow can persist late into the year, and high winds are common above the treeline. Always check weather forecasts before heading out.
Yes, the route passes by the Mount Antero & Baldwin Lake intersection, offering a notable landmark. Beyond that, the trail itself is a highlight, leading to the summit of a fourteener known for its gem fields and stunning 360-degree panoramic views of the Sawatch Range and other prominent peaks.
Yes, the route also passes through sections of the Upper Browns Creek 4Wd Road, Baldwin Creek 4Wd Road, Antero 4Wd Road, and the Mountain White 4Wd Road. These roads are often used by 4x4 vehicles, so be mindful of shared access.
Given the trail's difficulty and high altitude, essential items include plenty of water, high-energy snacks, layers of clothing (even in summer), rain gear, sun protection (hat, sunscreen), a map and compass or GPS device, a first-aid kit, and sturdy hiking boots. For winter or early season hikes, crampons or microspikes may be necessary.
