Grand Ditch Trail

The Grand Ditch Trail is generally considered suitable for trail running, with a relatively level path and gradual incline. The full length spans about 15 miles with approximately 656 feet (200 meters) of elevation gain. However, it's important to consider the high altitude of the region, which can make it feel more challenging for some. Sections connecting to the ditch trail, such as Red Mountain Trail or Thunder Pass, are considerably more difficult.

The trail primarily consists of an old, flat dirt road, often described as a 'doubletrack.' It is largely unpaved and packed down. While less technical than typical singletrack trails, the packed dirt can be harder on the feet and hips. Joggers should anticipate some unevenness.

You'll experience diverse and picturesque scenery, including subalpine and alpine forests with pine, fir, and spruce trees. During warmer months, open meadows burst with wildflowers. The area is home to various wildlife, such as elk, mule deer, moose, bald eagles, and mountain bluebirds. The trail also offers breathtaking views of the surrounding Never Summer Mountain Range.

The Grand Ditch itself is a notable engineering marvel. Constructed between the late 1800s and 1936, this nearly 15-mile long canal was built to divert water from the Never Summer Mountains to the east side of the Continental Divide for agricultural purposes. Jogging alongside it offers a tangible connection to Colorado's water management history.

The full route, which is approximately 39 kilometers (24 miles) out-and-back, typically takes around 5 hours to jog. This duration can vary based on your pace, fitness level, and how often you stop to enjoy the scenery.

Access to the Grand Ditch Trail is typically via trailheads within Rocky Mountain National Park. Specific parking areas will depend on your chosen starting point. It's advisable to check the Rocky Mountain National Park website for current parking information and any timed entry requirements, especially during peak seasons.

Yes, as the Grand Ditch Trail is located within Rocky Mountain National Park, you will need to pay the park's entrance fee. Additionally, during peak season (typically late May through mid-October), a timed entry permit may be required to access certain areas of the park, including the one leading to this trail. Always check the official Rocky Mountain National Park website for the most current regulations and reservation requirements before your visit.

The best time to jog the Grand Ditch Trail is typically from late spring through early fall (June to September). During these months, the weather is generally milder, wildflowers are in bloom, and the trail is free of snow. High altitude conditions mean that even in summer, mornings can be cool, and afternoon thunderstorms are common.
