Frequently asked questions

How long is the Grand Ditch Trail and how much climbing does the Grand Ditch Trail have?

The Grand Ditch Trail is 24.0 kilometers long, or about 15 miles, with roughly 213 meters of elevation gain, about 699 feet. That combination makes it a long but relatively gentle hike, with far less climbing than many Rocky Mountain National Park routes.

Is the Grand Ditch Trail in Rocky Mountain National Park easy or hard?

The Grand Ditch Trail is generally an easy hike by mountain-trail standards. Its 24.0-kilometer length makes it a substantial day or overnight outing, but the elevation gain is only 213 meters, so the challenge comes more from distance and exposure than from steep climbing.

Are dogs allowed on the Grand Ditch Trail in Rocky Mountain National Park?

Dogs are not allowed on the Grand Ditch Trail because it is inside Rocky Mountain National Park, where pets are prohibited on trails, tundra, and meadows. That means this route is not dog-friendly even though it follows a relatively gentle grade. ([alltrails.com](https://www.alltrails.com/trail/us/colorado/grand-ditch-trail?utm_source=openai))

Where do you start the Grand Ditch Trail and where can you park for the Grand Ditch Trail?

The Grand Ditch Trail is commonly accessed from the northwest side of Rocky Mountain National Park near the Colorado River Trailhead, west of Trail Ridge Road and not far from Grand Lake. The National Park Service identifies the Colorado River Trailhead as an access point for the Grand Ditch, so that is the key parking area to check when planning this hike. ([nps.gov](https://www.nps.gov/places/romo_corivertrailhead.htm?utm_source=openai))

Can you backpack the Grand Ditch Trail or is the Grand Ditch Trail only a day hike?

The Grand Ditch Trail works as either a long day hike or a backpacking trip. The route is listed as multi-day, and overnight travel in Rocky Mountain National Park is allowed only with a wilderness camping permit and reserved campsite, so any backpacking plan needs to follow park backcountry rules.

What is the best time of year to hike the Grand Ditch Trail in Colorado?

The usual hiking season for the Grand Ditch Trail is summer into early fall, with June through September being the most reliable window for dry trail conditions. Access can be more limited outside that period because Trail Ridge Road on the west side of the park is typically closed from mid-October until around Memorial Day.

What is the Grand Ditch on the Grand Ditch Trail and why is it historic?

The trail follows the Grand Ditch, a historic water-diversion canal first built in the 1890s to move water from the headwaters of the Colorado River across the Continental Divide toward the Cache la Poudre drainage. It is both a functioning ditch and a notable engineering feature, and the area is also tied to the well-known May 30, 2003 Grand Ditch breach in Rocky Mountain National Park.
