Hiking

Embark on a moderate hike along the Colorado Trail and Interlaken Trail, a route that spans 8.9 miles (14.4 km) and features 329 feet (100 metres) of elevation gain. This journey, estimated to take around 4 hours and 27 minutes, offers continuous views of Twin Lakes as you traverse through peaceful pine forests and vibrant aspen groves. You will experience diverse natural features, from rugged sections of the Colorado Trail to the gentle paths of the Interlaken Trail, providing a varied and engaging outdoor experience.

To make the most of your visit, plan your hike between late May and early October, avoiding the colder months. Starting your adventure in the morning is highly recommended to steer clear of afternoon thunderstorms, which are a common occurrence in the mountains. While you can generally find dispersed camping along parts of the Colorado Trail, formal campgrounds are scarce, so prepare your provisions carefully before heading out.

This route uniquely blends the renowned Colorado Trail with the historic Interlaken Trail, offering more than just scenic beauty. Keep an eye out for the majestic Sawatch Mountain range, including Mount Elbert, dominating the skyline. A notable highlight is the Interlaken Historic Resort, a fascinating ghost resort from the turn of the 20th century, providing a glimpse into the region's past as you explore the area.

Hiking southbound, this is the junction where you decide to hike the Collegiate West alternate (which follows the Continental Divide Trail) or the Collegiate East (which is the original Colorado Trail route). The CW West is more challenging, roughly ten miles longer and takes you into higher elevation, but offers breathtaking scenery, while the CW East stays lower and offers better accessibility to trail towns and hot springs.
