The Grand Ditch is an amazing feat of engineering built in the 1890s to move water from the Never Summer Mountains and the Grand Valley to Poudre Canyon and the Eastern Plains. It normally takes a hike of several miles to reach the Grand Ditch, but not at La Poudre Pass. Here is just takes a long drive and a short hike.
From the La Poudre Pass trailhead (directions below), follow the small, dirt trail pass the trailhead sign across the meadow. A tenth of a mile from the parking lot, the trail ends at a wide, dirt road. This is the Grand Ditch Road and our “trail.”
Turn right and head toward Rocky Mountain National Park. Along the road you may notice very tall posts. That’s to tell the plow operators where the road is, if they need to plow into this area before the snow melts completely.
About a quarter mile from the parking lot, you’ll pass through a gate and pass the sign that says you’re entering Rocky Mountain National Park. It’s another .2 mile to the La Poudre Pass Ranger Station. The ranger station has a cabin, barn and corral.
Here you’ll getyour first look at the Grand Ditch. It’s that simple ditch with water in it by the ranger station.
Cross a small bridge here and continue walking on the road. The ditch builders not only had to build a way for the water to be moved, they built a road along the ditch so maintenance crews could access the ditch.
It’s fascinating to walk along the ditch and imagine being in this remote area in the 1890s. The workers built nearly 15 miles of ditch. As you walk, look at the rock walls that had to be blasted in places to make room for the ditch.
At 1.45 miles from the parking lot, there’s a trail split. This is a great turnaround spot, or you can continue on the road for several miles.
On the way back, when you reach the small bridge at the ranger station, I recommend staying on the Grand Ditch Road and not crossing the bridge. Follow the overgrown road, along the ditch, to a gauging station. Here there’s another small bridge to cross over the ditch and return to the main road back to your car.
Details: The hike from La Poudre Pass to the Grand Ditch is about one mile roundtrip, but you can hike as far as you’d like, turning around when you’re ready.

Directions: From Fort Collins, take Highway 14 through town. When Highway 14 makes a left turn at a gas station (Ted’s Place), zero your odometer. Drive about 53 miles and turn left on Long Draw Road. From here, it’s about 12.9 miles to the trailhead at the end of this (at times, bumpy) dirt road.
