Mount Antero and Little Browns Creek Loop

This loop is consistently rated as difficult to very difficult. It involves a significant climb of around 4,000 feet, often requiring riders to hike-a-bike through dense pine forests and over rugged terrain above the tree line. The descent is also steep and technical, featuring loose rocks, large boulders, and high-speed turns, making it unsuitable for beginners. Very good fitness and advanced riding skills are essential.

The terrain is highly varied. You'll start with a steep, rocky climb through dense pine forests. As you gain elevation, the trees thin, revealing spectacular chalk cliffs. Above the tree line, expect rugged terrain with many granite boulders and some of the highest OHV trails in the country. The descent features medium loose rocks, large boulders, and sections with good grip, transitioning to wider trails with fewer obstacles at lower elevations.

The full loop, with its significant elevation gain and technical sections, can take approximately 7 hours and 45 minutes to complete for a variant gaining over 5,000 vertical feet. Given the '50/50 ride/hike-a-bike' nature, plan for a full day on the trail.

The loop offers diverse and breathtaking scenery. You'll pass through dense pine forests, encounter a waterfall, and reach a swim-able mountain lake. Higher up, enjoy spectacular chalk cliffs and expansive alpine wilderness. From the saddle between Mount Antero and Mount White, panoramic views of the surrounding mountains and the Arkansas Valley are available. Abundant wildflowers can also be seen, especially above the tree line in July.

Yes, the route includes notable sections such as the challenging Little Browns Creek Trail and the technical Switchbacks on the Colorado Trail. You'll also encounter a mountain lake with a sandy beach and ride on some of the highest OHV trails in the contiguous USA, offering above-treeline views of Mount Antero.

Specific parking information for the trailhead is best found by checking local Forest Service resources or detailed trail maps. Given the trail's location, parking is typically at designated trailhead lots within the San Isabel National Forest. Some riders opt to start from areas like Mount Princeton Hot Springs.

Generally, there are no specific permits or entrance fees required for day use on most trails within the San Isabel National Forest, including this loop. However, it's always a good idea to check the official USDA Forest Service website for the Salida Ranger District or local signage for any current regulations or fee requirements, especially if camping or using specific facilities.

Dogs are generally allowed on trails within the San Isabel National Forest. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all trail users. Be prepared to pack out all pet waste. Given the trail's difficulty and length, ensure your dog is fit enough for the strenuous conditions and high altitude.

The best time to ride this loop is typically from late June or early July through September, after the snow has melted from the higher elevations and before new snow arrives. July is particularly good for seeing abundant wildflowers above the tree line. Always check current weather conditions and trail status before heading out, as high-altitude weather can change rapidly.

Yes, for those looking to mitigate the strenuous climb, parts of the ascent, particularly up to 13,100 feet on Mount Antero, can be accessed via a shuttle in a high-clearance 4x4 vehicle. This allows riders to experience the high-altitude sections and the epic descent with less of the initial climbing effort.

Yes, the route incorporates sections of several other trails. You will ride on parts of the Collegiate East, the Colorado Trail (specifically Segment 14 Chalk Creek Trailhead to US-50 and Segment 13 North Cottonwood Creek Road to Chalk Creek Trailhead), Browns Creek Falls Trail, Wagon Loop Trail, and the Little Browns Creek Trail itself. It also utilizes sections of Baldwin Creek 4Wd Road and Upper Browns Creek 4Wd Road.

Given the trail's difficulty, high altitude, and remote sections, you should bring plenty of water (there is no reliable water source on the trail), high-energy snacks, a repair kit for your bike, a first-aid kit, and layers of clothing suitable for rapidly changing mountain weather. A GPS device or detailed map is also highly recommended for navigation.
