Step-by-Step Guide

1. Research and Plan Your Route

Before setting foot on the trail, thorough route planning is non-negotiable. Tom Mays South Ridge is not a loopits a point-to-point hike that typically begins at the South Ridge Trailhead near the intersection of Las Virgenes Road and Mulholland Highway and ends at the Tom Mays Trailhead near the top of the Santa Monica Mountains near the intersection with the Backbone Trail.

Use topographic maps from the USGS or digital platforms like Gaia GPS, AllTrails, or CalTopo to study elevation profiles, trail junctions, and water sources. The full South Ridge route spans approximately 7.5 miles with an elevation gain of roughly 2,200 feet. The trail is marked with blue diamond blazes, but signage is minimal in remote sections. Download offline maps and carry a physical map as a backup.

Check the National Park Service and Santa Monica Mountains Conservancy websites for current trail advisories. Seasonal closures due to fire damage, erosion, or wildlife activity are common. Always verify trail status the day before your hike.

2. Choose the Right Day and Time

Timing is everything on Tom Mays South Ridge. The trail faces south and receives intense sun exposure from mid-morning onward. The best days to hike are weekdays during late fall, winter, or early spring when temperatures range between 50F and 70F. Avoid weekends and holidays if you seek solitudethis trail, while less crowded than others, still sees increased traffic on popular weekends.

Start your hike before sunrise if possible. This allows you to reach the ridge before the heat builds, enjoy the quiet of dawn, and capture the best light for photography. If you must start later, aim to begin no later than 8:00 a.m. to avoid the peak heat between 11 a.m. and 3 p.m.

3. Prepare Your Gear

Proper gear transforms a difficult hike into a safe and enjoyable experience. Heres what you need:

• Footwear: Sturdy hiking boots with ankle support and aggressive tread. The trail includes loose scree, rocky outcrops, and uneven dirt paths that demand grip and stability.
• Backpack: A 2030 liter pack with hip support to carry water, snacks, layers, and emergency items.
• Hydration: Carry at least 3 liters of water per person. There are no reliable water sources along the route. A hydration bladder with a drinking tube is ideal for easy access.
• Navigation: GPS device or smartphone with offline maps (Gaia GPS or AllTrails Pro). A physical map and compass are essential backups.
• Layered Clothing: Temperatures vary significantly between the valley floor and ridge crest. Wear moisture-wicking base layers, a light insulating mid-layer, and a windproof shell. Avoid cotton.
• Sun Protection: Broad-spectrum SPF 50+ sunscreen, wide-brimmed hat, UV-blocking sunglasses, and a lightweight buff or neck gaiter.
• Emergency Kit: Include a first-aid kit with blister treatment, whistle, emergency blanket, headlamp with extra batteries, and a multi-tool.

Never hike alone. If you must go solo, leave a detailed itinerary with someone you trust, including your expected return time and trailhead coordinates.

4. Begin at the South Ridge Trailhead

The official trailhead is located off Las Virgenes Road, just east of the intersection with Mulholland Highway. There is no formal parking lotonly a narrow shoulder pull-off. Arrive early to secure a spot. Parking is limited to 1012 vehicles. Do not block gates, driveways, or private property.

Look for a small dirt path marked by a wooden sign that reads Tom Mays Trail South Ridge. The initial 0.3 miles follow a gentle incline through chaparral scrub. This section is relatively flat and serves as a warm-up. Stay on the main treadavoid creating new paths, which accelerates erosion.

5. Ascend Through the Chaparral and Transition to Ridge Top

After the first 0.5 miles, the trail begins to climb more steeply. The vegetation shifts from coastal sage scrub to dense chamise and manzanita. Watch for rattlesnakes in early spring and late fallthey are active during cooler parts of the day and often sun themselves on exposed rocks.

At approximately 1.2 miles, youll reach the first major viewpoint: a rocky outcrop offering your first glimpse of the Pacific Ocean and the Malibu coastline. This is a great place to pause, hydrate, and adjust your pace.

From here, the trail becomes more exposed. The switchbacks are fewer, and the ascent is direct. Use your hands for balance on steep, rocky sections. The trail narrows in placesstay centered and avoid stepping on loose rocks to prevent rockfall hazards below.

6. Navigate the Ridge Line

Between miles 2.5 and 5, youre on the true South Ridge. This is the heart of the hike. The terrain is open, windswept, and spectacular. To your left, the Los Angeles Basin stretches out below. To your right, the rugged backcountry of the Santa Monicas rolls toward the San Fernando Valley.

Trail markers are sparse here. Rely on your GPS and map. The ridge flattens slightly around mile 3.8this is a good place to rest and eat. Look for cairns (rock piles) left by previous hikersthey help confirm youre on the correct path when visibility is low due to dust or fog.

Watch for junctions. The South Ridge intersects with the Backbone Trail at mile 4.7. This junction is unmarked but identifiable by a wide, well-trodden path crossing from the west. Turn right (north) to continue on the South Ridge route. Do not take the left fork unless you intend to hike the full Backbone Trail loop.

7. Reach the Summit and Descend

The highest point of the South Ridge is approximately 2,300 feet above sea level and occurs around mile 5.2. There is no official sign, but the terrain flattens into a broad, grassy saddle with sweeping 360-degree views. This is the perfect spot for lunch and photos.

From here, the trail begins its descent toward the Tom Mays Trailhead. The descent is steep and rocky. Use trekking poles if you have themthey reduce impact on your knees by up to 30%. Take small, deliberate steps. Look for boot prints and worn earth to guide your path.

At mile 6.8, the trail enters a shaded oak woodland. The temperature drops noticeably. This is the final stretch before reaching the end. The trail becomes wider and more defined as it approaches the trailhead parking area off Las Virgenes Road, near the intersection with the Upper Las Virgenes Canyon Open Space Preserve.

8. Complete the Hike and Exit Safely

The official endpoint is a small gravel parking area with a kiosk and informational sign. Do not assume the hike is over once you reach this point. You must still hike an additional 0.4 miles on a dirt road to reach your vehicle if you parked at the South Ridge Trailhead. This road is not maintained for vehicleswalk it slowly and watch for loose gravel and wildlife.

Before leaving, take a moment to appreciate the landscape. Leave no trace. Pack out everything you brought in, including food wrappers, tissue, and even biodegradable items like fruit peels.

Best Practices

Practice Leave No Trace Principles

The Santa Monica Mountains are a fragile ecosystem. Every step you take has an impact. Follow these seven Leave No Trace principles rigorously:

1. Plan Ahead and Prepare: Know the rules, weather, and terrain. Bring enough water and food to avoid relying on natural sources.
2. Travel and Camp on Durable Surfaces: Stick to established trails. Avoid trampling vegetation, even if it seems dead or sparse.
3. Dispose of Waste Properly: Pack out all trash. Human waste must be buried in a cathole 68 inches deep and at least 200 feet from water, trails, and campsites. Use wag bags if required.
4. Leave What You Find: Do not pick flowers, collect rocks, or carve into trees. These actions degrade the natural experience for others.
5. Minimize Campfire Impacts: Fires are prohibited on this trail. Use a portable stove for cooking.
6. Respect Wildlife: Observe animals from a distance. Never feed them. Store food securely to avoid attracting coyotes or bears.
7. Be Considerate of Other Visitors: Yield to uphill hikers. Keep noise levels low. Use headphones for music or podcasts.

Manage Your Pace and Energy

Tom Mays South Ridge is not a race. Many hikers push too hard early and burn out before the ridge. Maintain a steady, conversational pace. If you cant speak in full sentences, youre going too fast.

Take short, frequent breaksevery 3045 minutesfor hydration and stretching. Use this time to scan your surroundings. Youll notice more wildlife, wildflowers, and geological features when you move slowly.

Hydrate and Fuel Strategically

Dehydration is the leading cause of hiking emergencies on this trail. Drink 810 ounces of water every 20 minutes, even if you dont feel thirsty. Electrolyte tablets or salt packets can help maintain sodium balance, especially in warm weather.

Carry high-energy snacks: trail mix, energy bars, dried fruit, and jerky. Avoid sugary snacks that cause energy crashes. Eat small portions every 45 minutes to sustain blood sugar.

Know Your Limits

Not every hiker is prepared for the physical demands of Tom Mays South Ridge. The trail includes sustained elevation gain, uneven footing, and exposure to sun and wind. If youre new to hiking, start with shorter, less technical trails like the Solstice Canyon Trail or the Temescal Canyon Loop to build endurance.

Signs of overexertion include dizziness, nausea, confusion, and muscle cramps. If you or a hiking partner exhibit these symptoms, stop immediately, find shade, hydrate, and reassess. Do not push throughaltitude sickness and heat illness can escalate quickly.

Respect Cultural and Ecological Significance

The land surrounding Tom Mays South Ridge is sacred to the Chumash people, who inhabited the region for over 10,000 years. Avoid disturbing rock formations, petroglyphs, or ceremonial sites. If you encounter artifacts, leave them undisturbed and report their location to the Santa Monica Mountains Conservancy.

Native plants like the California poppy, buckwheat, and sagebrush are vital to pollinators and soil stability. Do not step off the trail to photograph flowers. Use a zoom lens instead.

Real Examples

Example 1: A Solo Hikers Experience

Mark, a 38-year-old software engineer from Pasadena, completed the South Ridge hike in late January. He had trained for six weeks with hill repeats and weighted backpack walks. He started at 6:30 a.m., carrying 3.5 liters of water, two energy bars, and a lightweight down jacket.

The first mile felt easy, he said. But by mile 3, the wind picked up. I had to stop and put on my shell. The view from the ridge was unrealclear enough to see Catalina Island. I saw a red-tailed hawk circling above me. Thats when I knew I was in the right place.

Mark encountered a group of hikers near the summit who were lost. He used his Gaia GPS to confirm the correct path and directed them. I didnt know it then, but Id just become a trail steward, he said. Thats the magic of this trailit connects people.

Example 2: A Family Hike with Teens

The Rivera familyparents and two teenagershiked the South Ridge in March. They started at 7:00 a.m. and brought a drone for aerial footage. They planned to complete the hike in 5 hours.

My daughter thought it would be easy, said her father. But by mile 4, she was complaining. So we made a game: every time we saw a new plant, we had to name it. We found buckwheat, yucca, and even a rare silver lupine.

They took a 45-minute break at the summit, ate sandwiches, and took photos. The descent was tougher than expected. We used trekking poles for the first time, said the 16-year-old. I didnt think Id like them, but now Im getting my own pair.

They finished at 12:30 p.m., exhausted but proud. We didnt rush. We didnt take selfies at every turn. We just walkedand that was enough.

Example 3: A Photography Expedition

Lena, a landscape photographer from Santa Monica, hiked the South Ridge at dawn in April to capture the golden hour light over the Pacific. She carried a full-frame camera, tripod, filters, and extra batteries.

The light hits the ridge at exactly 6:47 a.m., she said. I timed my arrival to be there 15 minutes before. The mist rolled in from the ocean, and the chaparral glowed amber. I got 12 shots Ill never forget.

She stayed for three hours, waiting for the light to change. Most people hike to check a box. I hike to see what the land reveals. This trail doesnt give up its secrets easilybut when it does, its unforgettable.
