Step-by-Step Guide

1. Plan Your Trip Timing

Timing is critical when planning a day trip from San Francisco to Henry Cowell Redwoods. The park is open daily from 8:00 AM to sunset, but arrival time significantly impacts your experience. Aim to leave San Francisco between 6:00 AM and 7:00 AM to avoid weekend traffic and secure a parking spot at the main visitor center. Late afternoon arrivals may mean limited time on the trails before closing.

Seasonally, the best months to visit are April through October. Spring brings wildflowers and lush greenery, while summer offers warm, dry conditions ideal for hiking. Fall is less crowded and features golden light filtering through the canopy. Winter can be rainy and muddy, but the redwoods remain majesticjust be prepared with waterproof gear.

Check the official California State Parks website for alerts on trail closures, fire restrictions, or special events before departure.

2. Choose Your Route

There are two primary routes from San Francisco to Henry Cowell Redwoods State Park. Both are scenic, but differ in travel time and traffic conditions.

Route A: Direct Highway 1 (Most Popular)

Start on US-101 South from San Francisco. Merge onto CA-17 South near Santa Cruz. Take exit 34 for CA-9 South toward Felton. Continue on CA-9 for approximately 10 miles until you reach the park entrance on the right, marked by a large redwood sign. Total distance: ~70 miles. Estimated drive time: 1 hour 15 minutes without traffic.

Route B: Scenic Coastal Alternative

Take CA-1 South along the Pacific Coast Highway from San Francisco through Half Moon Bay, Santa Cruz, and Watsonville. This route adds 1520 minutes to your drive but offers breathtaking ocean views, coastal bluffs, and opportunities to stop at beaches like Natural Bridges State Beach or the Santa Cruz Wharf. Merge onto CA-9 near Davenport and follow signs to the park. Ideal for travelers who want to combine coastal and forest experiences.

Use Google Maps or Waze with Henry Cowell Redwoods State Park Visitor Center as your destination. Enable real-time traffic alerts to avoid delays on CA-17, which can experience congestion during weekend peak hours.

3. Arrive at the Visitor Center

Upon arrival, park in the main lot adjacent to the visitor center. There is a $10 vehicle day-use fee (as of 2024), payable via self-service kiosk or at the ranger station. Cash and credit cards are accepted. If you have a California State Parks Annual Pass, entry is free.

Stop at the visitor center to pick up a free park map, trail guide, and current conditions bulletin. Rangers are often on-site to answer questions and recommend trails based on your fitness level and interests. Dont miss the interpretive displays on redwood ecology, Native American history, and conservation efforts.

4. Select Your Trail

Henry Cowell offers over 15 miles of well-maintained trails, ranging from easy nature walks to moderate hikes. Here are the top three trails for first-time visitors:

Redwood Grove Loop Trail (1.2 miles, Easy)

This is the parks most iconic trail and a must-do for all visitors. The loop begins just behind the visitor center and winds through a 40-acre grove of towering coast redwoods (Sequoia sempervirens). The trail is flat, paved, and wheelchair-accessible in sections. Interpretive signs explain the biology of redwoodstheir fire resistance, root systems, and role in carbon sequestration. Look for the Big Tree, estimated to be over 1,200 years old, with a trunk diameter wider than a small car.

Big Trees Trail (2.5 miles, Easy to Moderate)

Starting at the same trailhead, this loop extends beyond the Redwood Grove and includes a gentle climb through mixed forest with Douglas fir, madrone, and bay laurel. The trail offers several overlooks and benches for rest. Youll pass through a section of second-growth forest, illustrating how redwoods regenerate after logging. The trail ends at the historic Santa Cruz Lumber Company site, where you can see remnants of 19th-century logging equipment.

Silver Creek Falls Trail (4.5 miles round trip, Moderate)

For those seeking a longer hike and a waterfall reward, this trail heads east from the visitor center on the Silver Creek Trail. After a steady climb through fern-filled understory, youll reach a 50-foot cascade tumbling over mossy rock. The trail is shaded and cool, even in summer. Bring water and wear sturdy shoessections can be slippery after rain. Return the same way or combine with the Redwood Grove Loop for a 5.7-mile loop.

5. Prepare for the Trail

Even on easy trails, preparation enhances safety and comfort:

• Wear closed-toe hiking shoes with gripdirt paths can be muddy or root-covered.
• Carry at least 1 liter of water per person, even on short hikes. The air is humid, and dehydration can occur subtly.
• Dress in layers. Temperatures in the redwood canopy can be 1015F cooler than the parking lot.
• Bring a small backpack with sunscreen, insect repellent, a hat, and a lightweight rain jacket.
• Leave no trace: Pack out all trash, including food wrappers and biodegradable items like apple cores.

Cell service is spotty in the park. Download offline maps via Google Maps or AllTrails before you leave. Inform someone of your planned route and return time.

6. Explore Beyond the Trails

Henry Cowell isnt just about hiking. After your walk, consider these additions:

• Visit the Redwood Grove Nature Center for interactive exhibits on forest ecosystems.
• Join a ranger-led walk (weekends only, check schedule at visitor center).
• Bring a sketchbook or cameraredwood groves are among the most photographed natural sites in California.
• Relax at the picnic area near the parking lot. Benches and tables are shaded by redwoods and perfect for a quiet lunch.

7. Return to San Francisco

Plan your return with traffic in mind. Depart the park by 4:00 PM to avoid the worst of the Friday or Sunday evening rush on CA-17. If you took the coastal route, consider stopping at the town of Santa Cruz for ice cream at the famous Beach Boardwalk or fresh seafood at a harbor restaurant.

As you drive back, reflect on the experience: the silence beneath the canopy, the scent of damp earth and cedar, the scale of trees older than the United States. These moments are why the journey matters.

Best Practices

Respect the Redwoods

Coast redwoods are among the most resilient yet vulnerable trees on Earth. Their shallow root systems spread wide but are easily damaged by foot traffic, vehicles, or compacted soil. Never walk on root systems, climb on trunks, or carve into bark. Even small acts of disrespect can have long-term consequences for these ancient giants.

Stay on designated trails. Off-trail hiking may seem harmless, but it disturbs understory plants and increases erosion. Redwood forests take decades to recover from such damage.

Leave No Trace Principles

Apply the seven Leave No Trace principles to your visit:

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 outside designated areas).
6. Respect wildlifeobserve from a distance.
7. Be considerate of other visitors.

Use restrooms at the visitor center. Do not dig catholes or urinate near trails or water sources. Biodegradable soap is not permitted near streams.

Wildlife Awareness

Henry Cowell is home to black-tailed deer, bobcats, raccoons, and over 100 bird species, including the endangered spotted owl. Never feed wildlife. Store food securely in your car. If you encounter a deer or coyote, give them space. Do not approach or attempt to photograph them closely.

Ticks are present in grassy and wooded areas. After your hike, perform a full-body tick check. Shower within two hours if possible. Lyme disease is rare but preventable with vigilance.

Weather and Terrain Readiness

Even in summer, redwood groves remain cool and damp. Temperatures rarely exceed 75F under the canopy. Mist and fog are common, especially in the morning. Always carry a light rain shell, even if the forecast is clear.

Trail surfaces vary: paved, gravel, dirt, and root-covered paths. Hiking poles are not required but helpful on the Silver Creek Falls trail. Children should be supervised on uneven terrain.

Group Size and Safety

Group hikes are encouraged, but keep groups small (68 people max) to minimize impact and maintain quiet. Larger groups can disturb wildlife and other visitors.

Bring a fully charged phone, but rely on offline tools. A physical map is your best backup. If someone in your group has a medical condition, carry a basic first-aid kit with bandages, antiseptic, and any necessary medications.

Photography Etiquette

Redwood groves are popular for photography. To protect the environment and respect others:

• Use tripods only on designated areas to avoid trampling vegetation.
• Do not use flash near sensitive wildlife or in enclosed grovesit can startle animals.
• Be patient. Wait for other photographers to finish before moving in.
• Do not move branches, rocks, or leaves to improve your shot.

Seasonal Considerations

Spring (MarchMay): Wildflowers bloom along trail edges. Mornings are misty and magical. Trails may be muddy after rainwear waterproof boots.

Summer (JuneAugust): Peak season. Crowds are highest on weekends. Arrive early. Water sources dry upcarry your own.

Fall (SeptemberNovember): Fewer visitors. Golden light filters beautifully through the trees. Cool evenings make for perfect hiking weather.

Winter (DecemberFebruary): Rainy and quiet. Trails are less crowded but can be slippery. Avoid hiking after heavy rain due to potential landslides on steeper trails. The waterfalls are at their most powerful.

Real Examples

Example 1: The Family Day Trip

Sarah and Mark, both software engineers from San Francisco, took their two children (ages 7 and 10) to Henry Cowell on a Saturday in May. They left at 6:30 AM, avoiding traffic on CA-17. After a quick stop at a bakery in Santa Cruz for pastries, they arrived at the park by 8:15 AM. They started with the Redwood Grove Loop, letting the kids touch the bark and count the rings on interpretive signs. They packed a picnic lunch and ate under a redwood near the picnic area. The children loved spotting banana slugs and ferns. They ended with a 20-minute ranger talk on how redwoods survive fires. The kids asked to return next month. Total time: 5 hours. Cost: $10 parking + $20 for snacks. Memory: It felt like stepping into a living museum.

Example 2: The Solo Hiker

James, a 58-year-old retiree from Oakland, hikes Henry Cowell once a month. He prefers weekdays and arrives by 7:00 AM. His routine: Redwood Grove Loop (1.2 miles), then the Big Trees Trail (2.5 miles), then sit quietly on a bench near the old lumber mill. He brings a thermos of tea and a journal. He writes observations: Today, the fog lifted at 9:15. A woodpecker drummed on a dead fir. The air smelled like wet moss and pine. He doesnt take photos. I want to remember it with my senses, not my phone. He says the hikes help him process grief after losing his wife. The trees dont hurry. Neither do I anymore.

Example 3: The Photography Expedition

Two friends, Lena and Diego, both professional photographers from Berkeley, planned a sunrise shoot at Henry Cowell in October. They arrived at 5:30 AM, parked, and walked the Redwood Grove Loop with tripods and a drone (approved for use in designated zones). They captured shafts of golden light piercing the canopy, dew on spiderwebs, and the texture of redwood bark. They used a polarizing filter to reduce glare on wet surfaces. They stayed until noon, then drove to the coast for lunch. Their photos were featured in a local gallery and used in a state park conservation campaign. The redwoods dont pose, Lena said. You have to wait for them to reveal themselves.

Example 4: The Educational Field Trip

A high school biology class from San Mateo visited Henry Cowell as part of an ecology unit. Their teacher, Dr. Ruiz, designed a pre-trip lesson on carbon storage and forest succession. Students measured tree diameters using clinometers, collected leaf samples, and recorded bird calls. After the hike, they wrote reflections comparing the old-growth grove to the second-growth forest. I thought redwoods were just tall trees, said one student. Now I know theyre ecosystemsliving libraries. The park ranger gave them a tour of the conservation lab, where they saw how scientists study tree rings to understand climate change.
