How to Hike Heartwell Golf Course Loop

The Heartwell Golf Course Loop is a hidden gem nestled in the heart of suburban greenery, offering hikers a serene, scenic, and surprisingly challenging trail experience—despite its origins as a private golf course. Once a well-maintained fairway and greenspace, parts of the Heartwell Golf Course have been repurposed into a public multi-use trail system, creating one of the most accessible yet under-the-radar hiking loops in the region. Unlike traditional wilderness trails, the Heartwell Loop blends manicured paths with natural woodland edges, providing a unique hybrid experience that’s ideal for beginners seeking a safe, well-marked route and seasoned hikers looking for a quiet, low-traffic alternative to crowded parks.

Understanding how to hike the Heartwell Golf Course Loop goes beyond simply following a path. It involves knowing the terrain, respecting the land’s dual history, preparing for variable weather conditions, and navigating subtle signage that may not always be obvious. This guide provides a comprehensive, step-by-step walkthrough of the entire loop, from entry points to trail etiquette, equipment recommendations, and real-world insights gathered from local hikers and park stewards. Whether you’re looking for a morning cardio session, a peaceful nature escape, or a photography-friendly route with seasonal blooms and wildlife sightings, mastering the Heartwell Loop will enhance your outdoor experience significantly.

Step-by-Step Guide

1. Locate and Access the Main Trailhead

The primary access point for the Heartwell Golf Course Loop is the North Gate Trailhead, located at the intersection of Maplewood Drive and Heritage Lane. This is the most commonly used entry point and is equipped with a small parking lot, a kiosk with a trail map, and a bench. If you’re arriving by car, GPS coordinates are approximately 34.0582° N, 118.2437° W. Public transit options include the Metro Line 18, which stops at the Heritage Lane Station—just a 7-minute walk from the trailhead.

Before stepping onto the trail, take a moment to review the printed map at the kiosk. While digital maps are helpful, physical signage is more reliable here due to intermittent cell service. Note the color-coded trail markers: blue for the main loop, yellow for side paths to restrooms and water fountains, and red for emergency exits.

2. Begin on the Blue Loop Trail (Clockwise Direction)

Start your hike by heading east along the wide, crushed-gravel path marked with blue diamonds. This section follows the former 1st fairway and is gently sloped, making it ideal for warming up. The trail is shaded by mature oaks and sycamores, and you’ll soon pass the remnants of the old clubhouse—now a community art pavilion. Look for interpretive signs along this stretch detailing the course’s history, including when it opened in 1957 and the native plant restoration project initiated in 2015.

For the first 0.6 miles, the path is flat and well-paved. Keep an eye out for wildlife: deer frequently graze near the eastern tree line at dawn and dusk. Avoid sudden movements or loud noises to prevent startling animals. This is also the best section for birdwatching—listen for the call of the western bluebird and watch for red-tailed hawks circling above.

3. Navigate the Transition to the Woodland Section

At approximately 0.7 miles, the trail begins to curve northward and enters the transition zone. Here, the gravel gives way to packed dirt, and the terrain becomes slightly uneven. This is where the former roughs and bunkers have been allowed to return to natural state. The path narrows, and you’ll encounter roots and small rocks. Wear sturdy footwear with good ankle support—flip-flops or lightweight sneakers are not recommended here.

At the 1.1-mile mark, you’ll reach the first trail junction. Do not take the yellow-marked path to the right—it leads to a maintenance shed and is closed to the public. Stay on the blue loop, which continues straight ahead and begins to climb gently. This incline, though modest (a 5% grade over 0.3 miles), is the most physically demanding part of the loop. Take your time, use the wooden handrails if needed, and hydrate.

4. Cross the Creek Bridge and Enter the Wetland Buffer

At 1.4 miles, the trail crosses a wooden footbridge over Heartwell Creek—a small, seasonal waterway that flows only after heavy rains. Even in dry months, the area around the bridge is lush with ferns, wild ginger, and poison oak (which you’ll want to avoid). Look for the warning signs painted on nearby trees: “Poison Oak—Do Not Touch.” If you’re unsure whether a plant is poison oak, remember the rhyme: “Leaves of three, let it be.”

After crossing the bridge, the trail enters a designated wetland buffer zone. This area is protected by local conservation ordinances, so stay strictly on the marked path. Boardwalks have been installed here to prevent erosion and protect sensitive root systems. You may hear frogs or see dragonflies hovering over the water. This is also a prime spot for spotting great blue herons during spring and fall migration.

5. Traverse the Former Fairway 9 to 18 Section

Once you exit the wetland, the trail opens into a wide, grassy corridor that once served as fairways 9 through 18. This section is the most visually striking part of the loop. The open sky, rolling terrain, and distant views of the city skyline create a surreal contrast between nature and urban development. The path here is flat and wide, perfect for taking photos or pausing to rest.

At 2.2 miles, you’ll pass the old 18th green—a circular depression now overgrown with wildflowers. In late April and early May, the area bursts into color with poppies, lupines, and California poppy hybrids. This is a popular spot for local photographers, so be respectful of others and avoid stepping on the flowers.

6. Ascend the Ridge Path and Reach the Viewpoint

From the 18th green, the trail turns sharply northeast and begins a moderate climb up a ridge known locally as “The Lookout.” This 0.4-mile ascent has a 12% grade and features a series of switchbacks. The trail here is rocky and exposed, so wear gloves if you need to use your hands for balance. The climb rewards you with panoramic views of the valley below and, on clear days, the distant peaks of the San Gabriel Mountains.

At the top, you’ll find a stone observation platform with a bench and a metal plaque commemorating the volunteers who helped convert the course into a public trail. Take a few minutes here to rest, hydrate, and enjoy the view. This is also a great place to check your watch—this section typically takes hikers 10 to 15 minutes to complete, depending on pace.

7. Descend and Return Along the Back Nine Path

From the viewpoint, the trail descends along the same ridge but on a different route—this is the “Back Nine Path,” marked by blue diamonds with a small white stripe. The descent is smoother and less steep, with a series of wooden steps and retaining walls built to control erosion. As you descend, you’ll pass through a stand of eucalyptus trees that release a fragrant aroma, especially in the morning.

At 3.3 miles, you’ll re-enter the original fairway corridor, now on the opposite side from your outbound journey. The path here is wide and flat again. You’ll pass the remnants of the old 7th tee box and the 6th green, both now used as picnic spots. If you’re hiking in the afternoon, you may find locals enjoying lunch under the shade of the large pine trees.

8. Final Stretch and Return to the Trailhead

The last 0.7 miles return you to the North Gate Trailhead along the same crushed-gravel path you started on. This final stretch is mostly flat with a slight downhill grade. Pay attention to the trail markers—they become less frequent here, but the path is unmistakable. As you approach the parking lot, you’ll pass the restored water fountain and the informational bulletin board, which often features upcoming trail cleanup events or guided nature walks.

Complete your hike by logging your time and distance on the self-service kiosk (optional but appreciated for trail maintenance tracking). If you’re feeling energized, consider walking the adjacent Heritage Lane Greenway, a paved path that connects to a larger regional trail network.

Best Practices

Timing Your Hike for Optimal Conditions

The Heartwell Golf Course Loop is accessible year-round, but the best time to hike is between late February and early June, when temperatures are mild and wildflowers are in bloom. Avoid midday hikes during summer months (July–September), as the exposed sections can reach temperatures over 95°F. Early morning (6–9 a.m.) is ideal for avoiding crowds and enjoying cooler temperatures. Evening hikes (4–7 p.m.) are also popular, especially in fall, when the light casts long shadows across the fairways and the air cools quickly.

Trail Etiquette and Respect for the Environment

Because the Heartwell Loop was once a private golf course, many visitors are unaware of its sensitive ecological status. Follow these guidelines to preserve the trail:

• Stay on marked paths. Straying off-trail damages native plant roots and disturbs wildlife habitats.
• Carry out all trash—including food wrappers, bottles, and biodegradable items like apple cores.
• Do not feed wildlife. Even well-intentioned feeding disrupts natural foraging behaviors.
• Keep noise levels low. Loud music, phone calls, and shouting disturb birds and other animals.
• Yield to others appropriately: hikers going uphill have the right-of-way; cyclists yield to all pedestrians.

Weather Preparedness

Weather on the Heartwell Loop can change rapidly. Even on sunny days, the ridge section can become windy and cool. Always carry:

• A lightweight windbreaker or fleece layer
• A reusable water bottle (at least 24 oz)
• A small first-aid kit with antiseptic wipes and blister pads
• A hat and sunscreen, even if it’s cloudy
• A fully charged phone (though service is spotty, it’s still useful for emergencies)

After heavy rain, the creek crossing may be impassable due to rising water. Check local park alerts before heading out. Rain also makes the trail muddy—trail shoes with deep treads are recommended.

Physical Preparation

The Heartwell Loop is approximately 4.0 miles round-trip with an elevation gain of about 320 feet. While not technically difficult, the uneven terrain and occasional inclines require a basic level of fitness. If you’re new to hiking:

• Begin with shorter walks (1–2 miles) on flat terrain to build endurance.
• Practice walking with a small daypack to simulate trail conditions.
• Stretch your calves, hamstrings, and hips before and after the hike.
• Take breaks as needed—there are multiple benches along the route.

Seasonal Considerations

Each season offers a different experience on the Heartwell Loop:

• Spring (March–May): Peak wildflower season. Best for photography and bird migration. Watch for poison oak and ticks.
• Summer (June–August): Hot and dry. Early morning hikes only. Carry extra water. Be alert for rattlesnakes, which are more active in the heat.
• Fall (September–November): Cooler temps, fewer crowds. Golden grasses and changing foliage. Excellent visibility for mountain views.
• Winter (December–February): Mild and rainy. Trails may be muddy. The creek may flow stronger. Avoid hiking after heavy rain if you’re uncomfortable with slippery surfaces.

Tools and Resources

Recommended Gear

While you don’t need high-end equipment to hike the Heartwell Loop, the right gear enhances comfort and safety:

• Footwear: Trail runners or low-ankle hiking shoes with grip (e.g., Merrell Moab 3, Salomon Speedcross 5).
• Backpack: A 10–15L daypack with a hydration sleeve (e.g., Osprey Arcane 12).
• Water: A 24–32 oz reusable bottle or hydration bladder. Refill stations are available at the trailhead and near the 18th green.
• Navigation: Download the offline map on AllTrails or Gaia GPS before you go. The Heartwell Loop is listed under “Heartwell Golf Course Trail” with user-uploaded photos and recent trail condition reports.
• Weather App: Use Windy or AccuWeather to check microclimate conditions for the area. The ridge often has different wind patterns than the valley below.
• First Aid: Include adhesive bandages, antiseptic, tweezers (for splinters or ticks), and antihistamine cream for insect bites.
• Optional: Binoculars for birdwatching, a lightweight notebook for journaling, or a camera with a zoom lens for capturing distant wildlife.

Mobile Apps and Digital Tools

While physical signage is primary, digital tools can supplement your experience:

• AllTrails: Search “Heartwell Golf Course Loop.” Over 1,200 user reviews provide up-to-date trail conditions, recent photos, and warnings about closures or hazards.
• Gaia GPS: Download the offline map for the area. The trail is preloaded in the “California Regional Trails” pack.
• Seek by iNaturalist: Use this app to identify plants and animals you encounter. It’s particularly useful for recognizing native flora like California lilac or deerweed.

Community Resources and Volunteer Programs

The Heartwell Loop is maintained by a coalition of volunteers and the City Parks Department. You can contribute by:

• Joining the monthly “Trail Stewards” cleanup (first Saturday of each month, 9 a.m. at the North Gate).
• Reporting trail damage or hazards via the online form at www.heartwellparks.org/report-issue.
• Participating in guided “Nature Walks” hosted by local botanists and ornithologists.
• Donating to the Heartwell Trail Conservancy, which funds signage upgrades and erosion control.

Many hikers who return regularly become part of the trail’s unofficial “guardians”—noticing changes, helping lost visitors, and sharing knowledge. Your participation helps keep this space accessible and protected.

Real Examples

Case Study 1: Sarah’s First Hike – From Couch to Loop

Sarah, a 32-year-old office worker, had never hiked before. After months of back pain from sitting, her physical therapist recommended daily walks. She started with 10-minute strolls around her neighborhood, then progressed to local parks. After reading about the Heartwell Loop on a wellness blog, she decided to try it.

She arrived at the North Gate on a crisp April morning. Following the step-by-step guide, she took her time, rested at every bench, and used the app to identify flowers. She completed the loop in 1 hour and 45 minutes, feeling proud and energized. Two weeks later, she returned with a friend. Now, she hikes the loop twice a week and has started a walking group called “Trail Beginnings.”

Case Study 2: Marco’s Photography Expedition

Marco, a landscape photographer, used the Heartwell Loop as a testing ground for his new wide-angle lens. He visited during golden hour in late May, capturing the way the sun hit the wildflowers on the 18th green and the mist rising off the creek at dawn. He posted his images on Instagram with the hashtag

HeartwellLoop, which went viral locally.

His photos helped raise awareness about the trail’s beauty and led to increased visitation. He later partnered with the Parks Department to lead a “Photography on the Trail” workshop, teaching others how to capture nature responsibly without disturbing wildlife. His most popular shot—a heron standing still in the wetland buffer—is now used on official trail brochures.

Case Study 3: The Emergency Rescue

In October, a 68-year-old hiker named Robert slipped on a wet rock near the ridge and twisted his ankle. He was alone, and his phone had no signal. He remembered the emergency call box located 150 feet from the viewpoint and pressed the button. Within 12 minutes, a park ranger arrived with a first-aid kit and a stretcher. He was transported to a nearby clinic and made a full recovery.

Robert later wrote a letter to the Parks Department thanking them for installing the call boxes. His story prompted a review of all emergency points on the trail, leading to the addition of solar-powered signal boosters and QR codes linking to emergency protocols.

Case Study 4: The Community Cleanup

In March 2023, a group of high school students from the Environmental Science Club organized a trash pickup on the Heartwell Loop. They collected over 200 pounds of litter—including plastic bottles, cigarette butts, and discarded golf balls. Their efforts were featured in the local newspaper and inspired a citywide “Adopt-a-Trail” program.

Today, over 30 local families “adopt” sections of the loop, committing to monthly cleanups. The trail is noticeably cleaner, and wildlife sightings have increased. This grassroots initiative demonstrates how community involvement transforms a simple trail into a living, cared-for ecosystem.
