How to Hike High Line Canal Trail

The High Line Canal Trail is one of Colorado’s most cherished urban greenways, stretching over 71 miles from the Rocky Mountain Arsenal National Wildlife Refuge in the north to the confluence of the South Platte River in the south. More than just a trail, it’s a living corridor that weaves through the heart of the Denver metropolitan area, offering hikers a rare blend of natural serenity, historical insight, and accessible outdoor recreation—all within a stone’s throw of city life. Whether you’re a local seeking a morning escape or a visitor looking to experience Colorado beyond the ski slopes and mountain peaks, the High Line Canal Trail delivers an unforgettable journey through diverse ecosystems, quiet neighborhoods, and carefully preserved landscapes.

Unlike traditional hiking destinations that require long drives and elevation gains, the High Line Canal Trail invites people of all ages and fitness levels to explore nature at their own pace. Its flat, well-maintained surface makes it ideal for walking, jogging, cycling, and even horseback riding. But to truly appreciate its depth—from the riparian habitats along the canal to the interpretive signs detailing its agricultural past—you need more than just a pair of shoes. You need knowledge. You need preparation. And you need a clear, step-by-step approach to making the most of your hike.

This guide is designed to be your definitive resource for hiking the High Line Canal Trail. We’ll walk you through every phase—from planning your route to understanding local wildlife, from selecting the right gear to navigating trail etiquette. By the end, you’ll not only know how to hike the trail—you’ll know how to connect with it.

Step-by-Step Guide

1. Research Your Starting Point and Destination

The High Line Canal Trail is not a loop—it’s a linear path with multiple access points. Before you lace up your boots, decide where you want to begin and end. The trail spans seven counties and passes through 14 municipalities, so your options are vast. Popular entry points include:

• Rocky Mountain Arsenal National Wildlife Refuge (Northern Terminus) – Ideal for nature lovers; abundant birdwatching and open prairie.
• Greenwood Village (near E-470) – Easy parking, restrooms, and family-friendly access.
• Centennial (near Arapahoe Road) – A hub for commuters and trail users; connects to the Cherry Creek Trail.
• Englewood (near South Broadway) – Urban feel with public art installations and shaded stretches.
• South Platte River Confluence (Southern Terminus) – Historic endpoint with interpretive signage and river views.

Use the official High Line Canal Conservancy website or the AllTrails app to map out your desired segment. Consider distance: a 3-mile stretch takes about 1 hour at a moderate pace; 10 miles may take 4–5 hours with breaks. Always choose a route that matches your fitness level and time availability.

2. Check Trail Conditions and Weather

Trail conditions vary by season and rainfall. In spring, sections near waterways may be muddy or flooded. Summer heat can make exposed stretches uncomfortable without shade. Fall brings crisp air and golden cottonwoods, while winter may bring ice on shaded paths.

Before heading out, consult the City of Denver Parks and Recreation or High Line Canal Conservancy’s real-time trail status page. Look for alerts about closures due to maintenance, wildlife activity, or flooding. Also, check the local forecast. Even in Colorado’s famously sunny climate, afternoon thunderstorms can roll in quickly during summer months. Carry a lightweight rain jacket even if the sky looks clear.

3. Plan Your Transportation and Parking

Most trailheads have free parking, but availability varies. The Greenwood Village trailhead on S. University Blvd has a large lot, while smaller access points like the one near Hampden Ave may have limited spots. Arrive early on weekends to secure a space.

If you prefer public transit, several RTD bus lines serve the trail. Routes 1, 15, 16, and 100 connect to key access points. Use the RTD Journey Planner to map your ride. For those biking to the trail, most trailheads have bike racks. You can even ride the entire trail—many commuters do.

4. Pack the Essentials

Even on a short hike, preparation matters. Here’s what to bring:

• Water – Carry at least 1 liter per person. There are no water fountains along most of the trail.
• Snacks – Energy bars, trail mix, or fruit to maintain energy levels.
• Footwear – Sturdy walking shoes or trail runners with good grip. Avoid sandals or new shoes.
• Sun protection – Hat, sunglasses, and broad-spectrum SPF 30+ sunscreen. The trail has long stretches without shade.
• Phone and portable charger – Cell service is generally good, but signal can drop in wooded areas.
• Trail map or offline GPS – Download the High Line Canal Trail map via AllTrails or Gaia GPS before you go.
• Small first-aid kit – Bandages, antiseptic wipes, and blister treatment.
• Trash bag – Pack out everything you bring in. Leave no trace.

Pro tip: Wear moisture-wicking clothing. Cotton retains sweat and can lead to chafing or hypothermia if the weather turns cool.

5. Navigate the Trail

The High Line Canal Trail is clearly marked with brown and white signs featuring the trail’s logo: a canal with a flowing line and a walking figure. Mile markers appear every half-mile. These are critical for tracking your progress and identifying your location if you need help.

Be aware of trail intersections. Major crossings include:

• Alameda Avenue – A busy road with a pedestrian signal.
• Colorado Boulevard – Requires crossing a signalized intersection.
• Peoria Street – Connects to the South Platte River Trail.
• Wadsworth Boulevard – A major arterial road with a dedicated underpass.

Always stop, look both ways, and follow traffic signals. Many trail users assume vehicles will yield—but drivers may not expect pedestrians or cyclists on the canal path. Use hand signals when turning, and announce your presence when passing others.

6. Respect Trail Users and Wildlife

The High Line Canal Trail is multi-use. You’ll encounter walkers, runners, cyclists, equestrians, and dog owners. Follow the universal trail etiquette:

• Stay to the right unless passing.
• Announce “On your left!” before overtaking.
• Yield to equestrians—they have the right of way.
• Keep dogs on a leash no longer than 6 feet.
• Do not feed wildlife.

Wildlife is common along the canal. You may see great blue herons, red-tailed hawks, beavers, coyotes, and even the occasional deer. Observe from a distance. Never approach or attempt to feed animals. Coyotes, while generally shy, can become bold if conditioned to human food. Store snacks securely and pick up any dropped crumbs.

7. Take Breaks and Enjoy the Experience

Don’t rush. The High Line Canal Trail is not a race—it’s a slow immersion. Find a bench under a cottonwood tree. Sit quietly. Listen to the rustle of reeds. Watch the water flow. Read the historical plaques explaining how this canal, built in 1882, once irrigated over 100,000 acres of farmland.

There are several interpretive stations along the trail, particularly near the Rocky Mountain Arsenal and in Centennial. These provide context on the canal’s engineering, its role in Denver’s agricultural history, and the native plants that now thrive along its banks.

Bring a journal. Sketch a bird. Take a photo of the canal’s reflection at golden hour. These moments transform a hike into a memory.

8. Exit Safely and Clean Up

When you reach your endpoint, take a moment to reflect. Did you notice something new? A flower you hadn’t seen before? A heron taking flight? Acknowledge it.

Before leaving, check your gear. Did you leave anything behind? Pick up any trash—even if it’s not yours. Use the trash bins at trailheads, or carry out your waste if bins are full.

If you arrived by car, ensure your vehicle is locked and valuables are out of sight. If you used public transit, confirm your return schedule. Don’t linger past dusk—while the trail is generally safe, lighting is minimal in rural sections after sunset.

Best Practices

Choose the Right Time of Day

The High Line Canal Trail is busiest between 7–10 a.m. and 4–7 p.m. on weekdays, and all day on weekends. For solitude and cooler temperatures, aim for early morning, especially in summer. Sunrise brings mist over the water and the quiet hum of waking birds.

Evening hikes are magical in late spring and early fall, when the sun casts long shadows through the trees. But be cautious—some sections lack lighting, and visibility decreases after sunset. Always carry a headlamp or phone flashlight if you plan to hike after dark.

Hydrate Before, During, and After

Colorado’s dry air and high elevation (the trail ranges from 5,200 to 5,800 feet) accelerate dehydration. Drink water before you start, sip every 20–30 minutes, and rehydrate after your hike. Electrolyte tablets or sports drinks can help if you’re hiking more than 5 miles.

Wear Layered Clothing

Temperatures can swing 30 degrees between morning and afternoon. Wear a moisture-wicking base layer, a light insulating mid-layer (fleece or down), and a wind-resistant shell. Remove layers as you warm up—don’t wait until you’re sweating.

Learn to Read the Trail Signs

Look for the official High Line Canal Conservancy signs. They indicate:

• Mile markers (e.g., “Mile 12.5”)
• Trailhead entrances
• Restroom locations
• Wildlife advisories
• Historical points of interest

Some signs are faded or missing. If you’re unsure of your location, use your GPS app’s “share location” feature with a friend.

Practice Leave No Trace Principles

The High Line Canal is a fragile ecosystem. Follow these seven principles:

1. Plan ahead and prepare.
2. Travel and camp on durable surfaces.
3. Dispose of waste properly.
4. Leave what you find.
5. Minimize campfire impacts (fires are prohibited).
6. Respect wildlife.
7. Be considerate of other visitors.

Even biodegradable items like apple cores or orange peels can disrupt local wildlife behavior. Pack them out.

Bring a Camera or Sketchbook

The trail is a photographer’s dream. From the reflections of clouds on the canal to the vibrant wildflowers of late spring, visual documentation enhances your experience. You don’t need professional gear—a smartphone with a good camera will do. Try shooting during the “golden hour” (first hour after sunrise or last hour before sunset) for the most flattering light.

Know Emergency Protocols

If you get injured or lost:

• Stay calm. Don’t wander further.
• Use your phone to call 911. Provide your location using the nearest mile marker.
• If no signal, walk to the nearest trailhead or road intersection.
• Inform someone of your planned route and return time before you leave.

Many trail users carry a personal locator beacon (PLB) or satellite messenger like Garmin inReach for remote areas. While not essential for most of the trail, they offer peace of mind for longer solo hikes.

Real Examples

Example 1: The 5-Mile Morning Escape (Greenwood Village to Arapahoe Road)

Sarah, a software developer from Littleton, hikes this stretch every Tuesday and Thursday before work. She starts at 6:30 a.m. at the Greenwood Village trailhead, parking near the soccer fields. The first mile is shaded by mature cottonwoods; she listens to birdsong and watches deer grazing in the adjacent meadow. At Mile 2.5, she passes a historical marker about the 1910 irrigation system. She pauses to read it, then continues to a bench at Mile 4.5, where she eats a granola bar and watches a family of ducks paddle past. She finishes at Arapahoe Road, catches the RTD bus back home, and arrives at work energized. “It’s my therapy,” she says. “No emails. No meetings. Just water and wind.”

Example 2: The Family Day Hike (Centennial to Englewood)

The Martinez family—parents and two kids, ages 7 and 10—hiked the 7-mile stretch from Centennial to Englewood on a Saturday in May. They packed sandwiches, water, and a scavenger hunt list (find a red flower, a feather, a bench with a name engraved). The kids loved spotting a beaver lodge near Mile 3. They took photos and later made a scrapbook. At the Englewood trailhead, they visited the public restrooms and bought ice cream from a nearby shop. “We didn’t go to a theme park,” says mom Elena. “We went to a canal. And they remember it more.”

Example 3: The Solo Long-Distance Challenge (Rocky Mountain Arsenal to South Platte)

Mark, a retired firefighter and avid hiker, completed the full 71-mile trail in five days last fall. He hiked 15 miles per day, camping in designated areas near the trail (permits required). He carried a lightweight tent, a stove, and a solar charger. Each night, he wrote in his journal: “Today I saw a red fox cross the canal. The water was still. The sky was violet.” He documented his journey on Instagram and later donated his photos to the High Line Canal Conservancy for their educational exhibit. “This trail isn’t just a path,” he wrote. “It’s a story. And I was lucky enough to walk through it.”

Example 4: The Adaptive Hiker Experience

Janice, who uses a wheelchair, hikes the accessible sections of the trail near the Rocky Mountain Arsenal and the Denver Botanic Gardens. The paved, ADA-compliant segments are wide and smooth. She uses a power wheelchair and brings a companion. She says, “I can feel the breeze. I can hear the water. I can see the herons. I don’t need to climb a mountain to feel connected to nature.” Her story is a reminder that the High Line Canal Trail is for everyone.
