Hiking the Colorado Trail from Waterton Canyon
The Colorado Trail stretches nearly 500 miles from the Denver area to Durango, weaving through six national forests, six wilderness areas and the headwaters of five major river systems. While some hikers (and mountain bikers) tackle the entire route over several weeks, most people experience it one section at a time — the trail is divided into 28 manageable segments. Mountain bikers are required to take detours around a handful of federal wilderness areas.
Waterton Canyon marks the official starting point. The first 6.5 miles follow a wide, hard-packed dirt road that traces the South Platte River through a dramatic rock canyon. Closed to cars and nearly flat, this stretch is especially accessible, making it ideal for families, casual hikers, cyclists and anyone looking for a scenic introduction to the Colorado Trail. With steep canyon walls rising on either side and the river flowing beside you, it offers a peaceful, traffic-free gateway into one of Colorado’s most iconic long-distance hikes.
What to Expect Hiking Waterton Canyon
Hiking Waterton Canyon is less about steep climbs and more about wide-open views, lush river scenery and the chance to spot wildlife. The first 6.5 miles follow a broad, hard-packed dirt road alongside the South Platte River, making it an approachable outing for hikers of all levels. Expect gentle terrain, dramatic rock formations and a steady soundtrack of rushing water.
Wildlife sightings are common here. Bighorn sheep often roam the canyon — sometimes grazing near the road or climbing sheer cliffs with impressive agility. Also, keep your eyes peeled for elk, deer, eagles and hawks. Black bears are rarer sights, but do pass through occasionally. Keep a respectful distance, even if they seem unfazed by people. The South Platte River is also popular with anglers (a valid Colorado fishing license is required). Some stretches are calm and dammed, forming quiet pools, while others run fast and free.
Strontia Springs Dam sits at the end of the route. From there, the Colorado Trail continues as more rugged singletrack for hikers and experienced mountain bikers. Ambitious cyclists can even ride from downtown Denver via the South Platte River Trail — a scenic, nearly 28-mile off-road journey to the canyon entrance.
