How to Hike Glen Canyon Park in San Francisco

Glen Canyon Park is one of San Francisco’s most serene and overlooked natural escapes—a 173-acre urban oasis nestled between the neighborhoods of Bernal Heights, Mission Terrace, and Crocker Amazon. Unlike the city’s more famous parks like Golden Gate or Golden Gate Park, Glen Canyon offers a quiet, immersive hiking experience with native flora, a seasonal creek, historic infrastructure, and panoramic views of the city skyline. For residents and visitors seeking solitude, exercise, and a tangible connection to San Francisco’s ecological heritage, hiking Glen Canyon Park is not just a recreational activity—it’s a gateway to understanding the city’s hidden natural rhythms.

This guide provides a comprehensive, step-by-step walkthrough of how to hike Glen Canyon Park, tailored for first-time visitors and seasoned hikers alike. Whether you’re looking for a 30-minute stroll or a full 2-hour nature immersion, this tutorial covers everything from trail access and navigation to safety, gear, and seasonal considerations. By the end, you’ll know how to plan, execute, and enjoy a meaningful hike through one of San Francisco’s most underappreciated green spaces.

Step-by-Step Guide

Step 1: Understand the Park’s Layout and Trail Network

Glen Canyon Park is not a single loop but a network of interconnected trails, staircases, and dirt paths that wind through a deep, narrow canyon carved by Glen Canyon Creek. The park spans from the southern end near 24th Street and Cesar Chavez Avenue to the northern entrance near the intersection of 19th Avenue and Sloat Boulevard. The primary trail system follows the creek bed, with elevated overlooks and side paths branching off to connect to surrounding neighborhoods.

There are three main access points:

• South Entrance (Cesar Chavez & 24th Street): Features a parking lot, restrooms, and the park’s main trailhead. This is the most popular starting point.
• North Entrance (19th Avenue & Sloat Boulevard): Offers a quieter entry with access to the upper trail and the historic Glen Canyon Bridge.
• East Entrance (Cortland Avenue & 18th Avenue): A lesser-used path that leads directly into the upper canyon and connects to the Glen Canyon Park Trail.

The main trail is approximately 1.5 miles one-way from south to north, but with side trails and overlooks, the total hiking distance can easily extend to 2.5–3 miles depending on your route. The trail is mostly flat to gently sloping, with a few steep staircases near the entrances. Elevation gain is minimal—under 200 feet total—making it accessible to most fitness levels.

Step 2: Choose Your Starting Point

Your starting point determines your experience. If you’re new to the park, begin at the South Entrance. This location has the most amenities and is easiest to reach via public transit. From here, you’ll follow the paved path downhill toward the creek bed. After about 100 yards, the trail transitions to packed earth and gravel. You’ll pass under a series of bridges—some historic, some modern—that span the creek.

If you prefer a more challenging ascent or want to avoid crowds, start at the North Entrance. This route begins on a paved sidewalk along Sloat Boulevard, then transitions to a steep staircase descending into the canyon. The climb back out is more strenuous, but the reward is a quieter, more secluded path and a unique view of the canyon from above.

For a loop hike, begin at the South Entrance, hike north to the Glen Canyon Bridge, then take the Cortland Avenue path back up to the east ridge, and return via the upper trail to your starting point. This loop is approximately 2.8 miles and includes varied terrain and elevation changes.

Step 3: Prepare Your Gear

While Glen Canyon Park is an urban park, its trails are natural and can be muddy, rocky, or overgrown depending on the season. Here’s what to bring:

• Sturdy footwear: Closed-toe shoes with grip are essential. Sneakers work for dry conditions, but hiking boots or trail runners are ideal after rain.
• Water: Carry at least 16 oz. There are no water fountains along the trail.
• Light snack: Energy bars or fruit help maintain energy, especially if you plan to linger at viewpoints.
• Weather-appropriate clothing: San Francisco’s microclimates mean it can be foggy and cool in the canyon even when it’s sunny downtown. Layer with a windbreaker or light jacket.
• Map or GPS: While the main trail is easy to follow, side paths can be confusing. Download the park map from the San Francisco Recreation & Parks Department website or use an offline app like AllTrails.
• Binoculars (optional): Great for spotting birds, raptors, or distant city landmarks.

Do not rely on cell service throughout the canyon—signal is spotty. Always inform someone of your planned route and return time.

Step 4: Navigate the Trail

Once you enter the park, follow the main trail downhill toward the creek. The path is well-marked with wooden signs and occasional painted arrows. After 0.3 miles, you’ll reach the first of several historic bridges—some dating back to the 1920s—that were originally built to carry water pipes across the canyon. These structures are now pedestrian crossings and offer excellent photo opportunities.

As you continue north, the canyon walls rise on either side, covered in native California sagebrush, wild lilac, and toyon. In spring, the creek may be flowing strongly, and you’ll hear the sound of water over rocks. In summer, the creek may be reduced to a trickle or dry completely—this is normal.

At approximately 0.8 miles, you’ll reach the Glen Canyon Bridge—a concrete arch bridge built in 1931 that spans the canyon near its widest point. This is a popular turnaround spot for casual hikers and a great place to rest and take in views of the surrounding hills and distant skyline.

If you continue past the bridge, the trail narrows and becomes more rugged. You’ll pass a small picnic area, then a series of switchbacks that lead to the upper trail. Look for a dirt path heading east—this is the Cortland Avenue connector. It climbs steeply through chaparral and offers a rewarding view of the entire canyon from above.

At the top, you’ll emerge near a residential street. Follow Cortland Avenue west to 18th Avenue, then head south to rejoin the main trail or return to your starting point via the upper ridge path.

Step 5: Time Your Hike

The best times to hike Glen Canyon Park are early morning (6–9 a.m.) and late afternoon (4–7 p.m.). Midday sun can be intense on the upper trails, and the canyon floor remains cool and shaded. Weekdays are significantly less crowded than weekends, especially in spring and fall.

Seasonal considerations:

• Spring (March–May): Wildflowers bloom, the creek flows, and bird activity peaks. This is the most scenic time to visit.
• Summer (June–August): Dry conditions dominate. The creek may be dry, but the upper trails offer cool breezes and panoramic views.
• Fall (September–November): Clear skies and mild temperatures. Ideal for photography and longer hikes.
• Winter (December–February): Rain can make trails muddy and slippery. Avoid hiking immediately after heavy rain. However, the canyon comes alive with flowing water and lush greenery.

Step 6: Respect the Environment

Glen Canyon Park is home to over 100 native plant species and several wildlife habitats, including nesting areas for red-tailed hawks, great blue herons, and the endangered California red-legged frog. Stay on designated trails to protect fragile soil and vegetation. Do not pick flowers, feed animals, or leave trash. Pack out everything you bring in.

Keep dogs on leash at all times. While dogs are allowed, they can disturb wildlife and other visitors. Always clean up after your pet.

Best Practices

1. Start Early to Avoid Crowds and Heat

Even though Glen Canyon Park is less visited than other city parks, weekend mornings can become busy with dog walkers, joggers, and families. Starting your hike before 8 a.m. ensures solitude, cooler temperatures, and better light for photography. Early mornings also increase your chances of spotting wildlife—deer, foxes, and even the occasional coyote are occasionally seen near the upper trail.

2. Use the “Leave No Trace” Principle

As an urban natural area, Glen Canyon Park relies on visitor responsibility to remain pristine. Follow these seven principles:

• Plan ahead and prepare.
• Travel and camp on durable surfaces.
• Dispose of waste properly.
• Leave what you find.
• Minimize campfire impact.
• Respect wildlife.
• Be considerate of other visitors.

Even small actions—like stepping off the trail to let a dog pass or picking up a stray piece of litter—make a big difference in preserving the park’s integrity.

3. Learn to Identify Native Plants and Wildlife

Enhance your hike by learning what you’re seeing. Common native plants include:

• California lilac (Ceanothus): Blooms in spring with clusters of blue or white flowers.
• Toyon (Heteromeles arbutifolia): Known as “California holly,” it bears bright red berries in winter.
• Coastal sage scrub: A low-growing, aromatic shrubland that dominates the upper slopes.

Wildlife to watch for:

• Red-tailed hawks: Often seen circling above the canyon rim.
• Western fence lizards: Sunbathing on rocks and logs.
• Black-tailed deer: Rare but occasionally spotted near the northern trail.
• Herons and kingfishers: Near the creek during wetter months.

Download a free native plant guide from the California Native Plant Society or use the Seek by iNaturalist app to identify flora and fauna on the trail.

4. Avoid Hazardous Conditions

While Glen Canyon Park is generally safe, be aware of potential hazards:

• Muddy or slippery trails after rain: The creek bed can become slick. Use trekking poles if available.
• Overgrown brush: In late summer, poison oak may appear along side trails. Learn to identify it: “Leaves of three, let it be.”
• Unmarked paths: Do not follow unofficial trails—they may lead to private property or unstable terrain.
• Wildlife encounters: If you see a coyote, do not approach. Make noise and slowly back away.

Always carry a fully charged phone, even if service is limited. Emergency contacts and park ranger numbers are listed on signage at trailheads.

5. Combine Your Hike with Nearby Attractions

Extend your outing by exploring nearby points of interest:

• San Francisco Botanical Garden (Golden Gate Park): A 55-acre garden with native California plants—perfect for comparing species you saw in Glen Canyon.
• Clarendon Heights Park: A small hilltop park with 360-degree views of the city, accessible via a short walk from the upper trail.
• Colma Creek Trail: A lesser-known path that connects Glen Canyon to the southern edge of the city, ideal for adventurous hikers.
• Local cafes: After your hike, refuel at nearby spots like Blue Bottle Coffee on 24th Street or El Charro for authentic Mexican fare.

Real Examples

Example 1: The Family Nature Day Out

Sarah and her two children, ages 7 and 10, visited Glen Canyon Park on a Saturday morning in April. They started at the south entrance, packed trail snacks, and brought binoculars. The kids loved spotting lizards and watching the creek flow under the bridges. They took photos of wildflowers and used the Seek app to identify them. After a 1.5-mile hike to the bridge, they picnicked on the grassy slope and returned the same way. Total time: 2 hours. Sarah said, “It felt like we were miles from the city, but we were just 15 minutes from home.”

Example 2: The Solo Hiker’s Morning Ritual

David, a 58-year-old retiree, hikes Glen Canyon Park every Tuesday and Thursday at 6:30 a.m. He starts at the north entrance, takes the steep descent, and walks to the creek bed before climbing back up via the Cortland path. He carries a journal and writes observations about bird calls, weather changes, and plant growth. Over three years, he’s documented over 40 bird species and noticed how the creek’s flow changes with seasonal rainfall. “This park is my therapy,” he says. “It reminds me that nature doesn’t need us—but we need it.”

Example 3: The Photography Expedition

Maya, a landscape photographer, planned a sunrise shoot in Glen Canyon Park during autumn. She arrived at 6 a.m., hiked to the upper ridge near Cortland Avenue, and captured the fog rolling through the canyon as the sun rose over the city. She used a tripod and wide-angle lens to emphasize the scale of the canyon walls. Her photo series, “Canyon in the Mist,” was later featured in a local art gallery. She credits the park’s unique topography and unpredictable weather for the series’ success.

Example 4: The Educational Field Trip

A local middle school biology class visited Glen Canyon Park as part of a unit on urban ecology. Students collected soil samples, identified native plants, and recorded bird sounds. They compared the biodiversity of the canyon to nearby paved areas. The park ranger led a discussion on how cities can support native species. “We thought we knew San Francisco,” said one student. “But this park showed us how much life is hiding in plain sight.”
