"This hike follows the Cache La Poudre River upstream from Poudre Canyon south to Grass Creek, at mile 3, and then on to a washed-out bridge at about mile 7. Parts of the trail are lovely flat strolls on pine needles at river level; other sections climb high on the wall of the magnificent gorge formed by the river. Some spectacular sections of the trail cross large talus slopes below the gorge walls.You will enjoy the big, open rock traverses, river views,wildflowers, and luxurious forest scenery."

"The Big South Trail continues over 10 miles along the banks of the Cache Le Poudre River and ends in Rocky Mountain National Park at Poudre Lake near Milner Pass. This described trek extends only 2.5 miles to the bridge over May Creek. The flowing waters of the Poudre are the feature of this outing. Snowshoers should have little trouble on this trail, but it is not recommended for cross-country skiers due to its steep curving sections along the narrow trail."

"The Big South is the sparkling south fork of the Cache la Poudre River that winds through a beautiful canyon as it rolls, tumbles, twists, and turns its way down from its origin in Rocky Mountain National Park. The trailhead is where CO 14 and the river part company, so you can hike along the wild and scenic river in the Comanche Peak Wilderness in peace away from the highway. This is a rolling, gradually climbing trail offering the cascading river, a mixed conifer and aspen forest, and the experience of trekking up the ever-changing canyon until it vanishes into deep forest green. Sections of the trail are very rocky because it skirts the edge of the compact arroyo, surrounded by richly stained colorful rock cliffs and rock falls. Three backcountry campsites a little more than 1 mile from the trailhead are nice for first-time backpacking experiences."
