Frequently Asked Questions

What is the terrain like on the South Colony Lakes Trail?

The trail begins on an old 4WD road, which can be steep and rocky but might be runnable in parts. As you ascend, it becomes more rugged, traversing through forests, around creeks, and through small boulder fields. Higher up, expect rock-hopping and light scrambling. Sturdy and comfortable shoes are highly recommended due to the rocky and uneven nature.

What can I see along the route to South Colony Lakes?

The route offers stunning alpine scenery. You'll pass through forested areas with views of iconic peaks like Crestone Needle, Crestone Peak, and Humboldt Peak. There are frequent stream crossings, and in July, wildflowers are abundant. The highlight is reaching South Colony Lake, which offers picturesque views and reflections of Crestone Needle, especially during morning alpenglow. The basin is surrounded by impressive 14ers and 13ers.

Is the South Colony Lakes Trail dog-friendly?

Yes, dogs are generally allowed on the trail within the Sangre de Cristo Wilderness. However, they must be kept on a leash to protect wildlife and ensure a pleasant experience for all visitors. Always practice Leave No Trace principles, including packing out all pet waste.

Do I need a permit or pay an entrance fee for the South Colony Lakes Trail?

As of current regulations, there are no specific permits required for day hiking or jogging the South Colony Lakes Trail, nor are there entrance fees for the Sangre de Cristo Wilderness Area. However, if you plan on backcountry camping, you may need to register or obtain a permit, so it's always best to check the latest regulations with the San Isabel National Forest before your trip.

What is the best time of year to visit the South Colony Lakes Trail?

The best time to visit is typically from late June through September. July is particularly beautiful with abundant wildflowers. During this period, snow has usually melted from the higher elevations, and the weather is generally more stable. Be prepared for rapidly changing weather conditions, even in summer, and always check the forecast before heading out.

How long does it take to jog the South Colony Lakes Trail?

While the trail is listed for jogging, continuous running is challenging due to its difficult terrain and significant elevation gain. The full round trip to the lakes is about 21.7 km. For strong trail runners prepared for power hiking sections, it could take anywhere from 4 to 7 hours, depending on your pace, stops for photos, and how far you explore beyond the main lake.

Where does the South Colony Lakes Trail start, and what are the parking options?

The trail officially starts at the end of the old 4WD road. Many visitors park at a lower 2WD trailhead and hike the initial, rougher section of the road. This adds significantly to the overall distance and elevation gain. Arriving early, especially on weekends, is crucial for securing a parking spot at either location.

Does the trail intersect other well-known paths?

Yes, the route primarily follows the South Colony Road for a significant portion. It also passes through sections of the South Colony Spur, the South Colony Trail, and briefly touches the Rainbow - 1336 trail. For those venturing higher, it can connect to the Broken Hand Pass trail, which leads towards the 14ers.

What wildlife might I encounter on the trail?

The Sangre de Cristo Wilderness is rich in wildlife. You might spot various bird species, squirrels, pikas, elk, deer, fox, coyote, and marmots. While less common, bears and bobcats also inhabit the area. Always maintain a safe distance and never feed wild animals.

Is the South Colony Lakes Trail suitable for beginners?

No, this trail is considered difficult and is not suitable for beginners, especially for jogging. It involves significant elevation gain, rocky and uneven terrain, and high altitude. It's best suited for experienced hikers or trail runners who are acclimated to high elevations and prepared for a challenging outing.

Are there any specific considerations for high altitude on this trail?

Yes, the trail reaches nearly 12,100 feet at the lakes, and even higher if you continue towards the peaks. High altitude can cause symptoms like headaches, nausea, and fatigue. It's crucial to acclimate if possible, stay hydrated, and be aware of the signs of altitude sickness. Turn back if symptoms worsen.
