Where can I park to access the CMC South Trail and Little Raven Trail?

For the Little Raven Trail, a common starting point is the Red Rock Trailhead, which leads to Brainard Lake. Remember that timed-entry reservations might be required for vehicle access to the Brainard Lake Recreation Area.

What is the terrain like on these trails?

The Little Raven Trail offers varied scenery, often following old logging roads with a surface of grass and dirt, winding through dense pine forests and around lakes. The CMC South Trail also guides you through beautiful pine forests, but can be more rugged and muddy in certain sections, offering spectacular views of Brainard Lake and the Continental Divide.

Is the combined route suitable for beginners?

The overall route, combining sections of both trails, is considered moderate in difficulty. While some segments of the Little Raven Trail are described as easy to moderate, the full combination involves nearly 10 km (6 miles) and some elevation gain, making it a good option for hikers with some experience or beginners looking for a bit more of a challenge.

What notable features or viewpoints can I expect along the way?

You'll traverse dense pine forests where moose sightings are possible, especially on the Little Raven Trail. The CMC South Trail provides spectacular views of Brainard Lake, the surrounding forest, and the high peaks of the Continental Divide.

Yes, the Little Raven Trail is suitable for mountain biking during the hiking season (May 1 to November 14). The CMC South Trail is also suitable for hiking, Nordic skiing, and snowshoeing, but specific mountain biking suitability should be confirmed with local regulations.

What should I wear or bring for a hike on this route?

Given the varied terrain and potential for changing weather in the Rocky Mountains, it's wise to wear layered clothing, sturdy hiking boots, and bring plenty of water. Sun protection (hat, sunscreen) is also recommended due to the high elevation. Depending on the season, be prepared for muddy sections, especially on the CMC South Trail.
