Ring Mountain Preserve crowns the Tiburon Peninsula, giving you one of Marin County’s most distinctive landscapes. This 385-acre open space welcomes hikers, cyclists, and horseback riders with trails that twist through rare rock outcrops and sweeping grasslands.
On a clear day, you get those jaw-dropping 360-degree views of the Bay Area—Tiburon, Corte Madera, and all the way across to San Francisco. The trails are pretty accessible for most folks, even if you’ve got little ones or a dog in tow. Just be ready for some uneven ground.

About Ring Mountain Preserve
Ring Mountain Preserve is a place where wild geology meets rare plants. It sits on the Tiburon Peninsula, and those 385 acres serve up big Bay views you won’t forget.
Location and Overview
Ring Mountain Preserve rises above the Tiburon Peninsula in Marin County, California. It’s an open space with easygoing hiking trails and some of the region’s best vistas. From up high, you’re looking out over San Francisco, the bay, and the green hills of Marin.
Most people can manage these trails. One reviewer even mentioned hiking with a friend, a 4-month-old baby, and a dog—so you don’t have to be a hardcore trekker to enjoy it. Families and folks looking for a mellow adventure will feel right at home.
Unique Geology and Landscape
What really sets Ring Mountain apart? The rocks. The preserve is packed with rare geologic formations, some dating back 165 million years. If you’re even a little curious about earth science, it’s a cool place to poke around.
Keep an eye out for:
- Amphibolite
- Eclogite
- Little garnet crystals
This landscape is just plain different from anything else in Marin. The oddball soil and microclimate mean you’ll also find rare plants here—stuff you won’t spot anywhere else on the California coast.
If you hit the trails in spring, you’ll get wildflower displays bursting against those ancient rocks. Not bad, right?
Getting to Ring Mountain Preserve
Getting here is simple, whether you’re coming from the city or elsewhere in the Bay Area. The preserve sits between Tiburon and Corte Madera, with clear trailheads and easy directions.
Directions from San Francisco
From San Francisco, jump on Highway 101 north over the Golden Gate. Go about 10 miles, then take the Paradise Drive/Tamalpais Avenue exit. Head east on Paradise Drive.
Keep following Paradise Drive toward Tiburon for around 1.3 miles (the road name changes a couple of times, but just keep straight).
Plug “Ring Mountain Preserve, Paradise Drive, Corte Madera” into your GPS for the fastest route.
With average traffic, you’ll get there in about 25-30 minutes from San Francisco.
Parking and Access Points
There are two main trailheads with parking:
Main Trailhead: Right on Paradise Drive, east of Corte Madera. Look for the preserve sign on your right as you head toward Tiburon. The lot’s small, but you’re right at the main trails.
Westward Drive Access: For a quick start, head to the end of Westward Drive in Corte Madera for another entry point.
Parking’s free at both spots, but weekends and holidays fill up fast. If you want a spot, aim to arrive before 9am on busy days.
Unlike some of Marin’s more famous parks, there’s no entrance fee here and usually less parking drama than places like Muir Woods.
Trail Systems and Routes
Ring Mountain Preserve has several marked trails that show off its natural beauty and those big Bay views. You’ll find easy strolls and tougher routes that wind through different habitats and viewpoints.
Phyllis Ellman Trail
The Phyllis Ellman Loop Trail runs 1.76 miles through some of the preserve’s most interesting scenery. It’s moderately challenging—think oak woodlands, wildflower-filled grasslands, and occasional little creeks if it’s rained.
Named for a local conservationist who helped save this land, the trail changes with the seasons. Expect cool rock features and shifting plant life as you go.
Bring sturdy shoes—the ground gets rocky and uneven in spots. There are plenty of places to pause and soak in the Bay views, especially in the soft morning light.
Loop Trail Options
You can mix and match loops to suit your mood. Combine the main loop with the Phyllis Ellman Trail for a 2.8-mile circuit—most folks finish it in about 90 minutes.
Expect:
- 400-500 feet of elevation gain
- Wide-open viewpoints over the Bay
- Access to all the key highlights
Trail signs at the junctions help keep you on track, even if it’s your first visit. In spring, wildflowers are everywhere. In fall, you get crisp air and long views.
Short on time? The lower loop cuts the hike to about 1.5 miles but still gets you to the good stuff.
Turtle Rock Route
For a quick adventure, check out the Turtle Rock route. This funky outcrop of serpentine looks a bit like a turtle from the right angle and is a favorite for geology fans and anyone chasing a great view.
Start from the Taylor Road access and it’s only about 0.5 miles, though you’ll scramble up some uneven ground.
At Turtle Rock, you get:
- 360-degree Marin and Bay views
- A peek at rare plants that love serpentine soils
- Wild rock shapes for photos
It’s a sunset hotspot—bring your camera, because the light on the rocks and hills is pretty amazing.

Hiking Experience
You’ve got options here, whether you want a short stroll or something more ambitious. The Phyllis Ellman Loop is the main event, at 1.76 miles with plenty of highlights along the way.
Scenic Vistas and 360 Degree Views
Ring Mountain’s high points make you feel like you’re standing on top of the world. From the summit, you can see the Bay, San Francisco’s skyline, the Richmond-San Rafael Bridge, and Mount Tam.
The main summit is the big photo spot, but Turtle Rock gives you a different angle. Both are worth the climb.
Photographers love Ring Mountain for a reason. On a clear day, you can see for miles—water, city, hills, the whole panorama.
Morning light throws dramatic shadows, while afternoons warm up the colors. It’s hard to take a bad photo up here.
Best Times to Visit
Spring (March-May) is the sweet spot. Hills go green, wildflowers explode, and the weather’s just right. Early mornings (7-9 AM) are cooler and the light’s perfect for photos.
If you can, go on a weekday for quieter trails. On weekends, get there before 9 AM for parking.
Fall is underrated—golden grasses, crisp air, and long-range views. In winter, after a rain, the creeks run and everything turns neon green.
Summer afternoons can get pretty toasty and there’s not much shade, so plan accordingly.
Wildflowers and Native Flora
Ring Mountain is a hotspot for rare and endangered plants. The Tiburon mariposa lily, a federally endangered wildflower, only grows here and blooms in late spring.
Along the trails you’ll spot:
- Purple owl’s clover
- California poppies
- Blue-eyed grass
- Lupines
- Native bunch grasses
The preserve’s serpentine soil creates weird, mineral-rich ground that only certain plants can handle. That’s why you’ll see species you won’t find anywhere else.
April is wildflower prime time—hillsides turn into a patchwork of color. Oak woodlands break up the grasslands and shelter even more plant life.
Outdoor Activities
Ring Mountain’s not just for hikers. The unique landscape is perfect for exploring, climbing, and just being outside.
Rock Climbing and Bouldering
Turtle Rock draws climbers for a reason. This big serpentine chunk has routes for beginners and seasoned folks alike. The rock’s got good grip and the bouldering problems range from easy to moderate.
Most climbing faces west, so afternoons are great when the rock isn’t scorching.
You’ll need to bring your own crash pads—the landings can be rough, and there’s no gear to rent here.
Stick to Leave No Trace basics. Don’t climb when the rock’s wet, and be gentle with the fragile plants around the boulders.
Wildlife Watching
With its mix of habitats, Ring Mountain is a solid spot for wildlife watching. The location near the bay means you might catch glimpses of land and marine animals.
Keep an eye out for harbor seals sunning themselves on rocks at low tide. Binoculars help, since they’re usually a ways off.
Birders will be happy too—hawks patrol the grasslands, and songbirds hide in the oaks.
Spring is the best for wildlife combined with wildflowers. Early or late in the day, you’ll see more animals and get that golden light.
Visitor Tips and Practical Information
Before you head out to Ring Mountain Preserve, it helps to know what to expect. There are a few rules and seasonal quirks to keep in mind for a safe, enjoyable trip.
Trail Etiquette and Safety
Bikes and horses stick to fire roads—don’t take them onto hiking trails. Keep to designated paths and roads so you don’t trample the sensitive ecosystems that make Ring Mountain unique. The preserve’s unusual landscapes really do need some care.
Try not to hike solo if you can avoid it. Bring a friend, and let someone know where you’re headed and when you’ll be back.
Cell phone coverage? It’s spotty in places. Download maps ahead of time or just bring a paper one—old school but reliable.
If you’re driving, park along Paradise Drive just past Westward Drive. Look for the small Ring Mountain sign. Parking fills up fast on weekends, so arriving early is smart.
Give wildlife space—watch from a distance. Don’t feed animals or mess with the plants.
Weather and What to Bring
Ring Mountain gets pretty windy, especially in the afternoons when the fog blows in. Layer up, even if it seems warm at the trailhead. A light windbreaker is honestly a must, any time of year.
Wear sturdy hiking shoes with decent grip. Some trails are rocky and get slick when wet.
Bring your own water—there aren’t any drinking fountains here. Pack at least a liter per person for a short hike.
Don’t skip sun protection, even if the sky’s gray. Sunscreen, a hat, sunglasses—just toss them in your bag.

A camera’s worth it for those views: San Francisco, Sausalito, Tiburon, the Richmond Bridge, the East Bay—on a clear day, it’s all right there.
Binoculars aren’t required, but they’re fun for birdwatching or just scoping out the distance.
Nearby Attractions and Day Trips
Ring Mountain Preserve makes a great jumping-off point for exploring Marin. This area’s packed with charming towns, beaches, and water activities just a short drive away.
Exploring Tiburon and Corte Madera
Tiburon’s only minutes from Ring Mountain and it’s got that postcard waterfront vibe. Main Street has shops, restaurants, and killer bay views. Sam’s Anchor Cafe is a classic—grab a table outside if you can for Golden Gate Bridge scenery.
Corte Madera mixes the outdoors with shopping. The Village at Corte Madera is the spot for upscale stores if you want a break from trails. For lunch, Pig in a Pickle serves up solid BBQ, and Boca Pizzeria does wood-fired pies.
Both towns run farmers markets—Tiburon on Thursdays (April-September), Corte Madera on Wednesdays (all year). You’ll find local produce, snacks, and artisan stuff.
Beaches and Coastal Activities
Marin’s beaches run the gamut from quiet coves to wild, open sand.
Favorites:
- Muir Beach (22 min west)
- Stinson Beach (35 min northwest)
- Rodeo Beach (30 min south)
Stinson Beach wins for amenities: restrooms, picnic spots, and food nearby. It’s a good pick for a full-on beach day, especially in summer when lifeguards are around.
For tidepooling, try Agate Beach near Bolinas at low tide—look for sea stars, anemones, maybe a harbor seal if you’re lucky.
South of Ring Mountain, the Marin Headlands have dramatic coastal trails and jaw-dropping views of the Golden Gate and San Francisco.
Kayaking and Water Sports
Richardson Bay’s calm waters are ideal for kayaking and paddleboarding, even if you’re new to it.
Rentals:
- Sea Trek (Sausalito) – Guided tours and hourly rentals
- 101 Surf Sports (San Rafael) – Gear and lessons
Mornings are usually calmer—less wind, easier paddling. Guided tours on Richardson Bay often spot harbor seals, herons, and other wildlife while you learn about the area’s ecology.
More experienced? Tomales Bay near Point Reyes is a standout for kayaking. In summer, you might catch bioluminescence on evening trips with Blue Waters Kayaking.
Windsurfers and kiteboarders should check out Crissy Field in San Francisco—steady wind makes it a hotspot.
Recommended Destinations in Marin County
Marin’s got plenty of natural gems besides Ring Mountain, each with its own vibe—coastlines, redwoods, mountain views.
Mount Tamalpais and Muir Woods
Mount Tamalpais (locals just call it Mt. Tam) is Marin’s signature peak at 2,571 feet. Over 60 miles of trails wind through forests and ridges with big Bay Area views. The East Peak visitor center gives you a quick intro to the mountain’s history.
Down at Mt. Tam’s base, Muir Woods National Monument preserves a primeval redwood forest. Some trees tower over 250 feet and have been around for a thousand years. The main trail is paved and wheelchair-friendly for about a mile.
Weekday mornings are your best bet to dodge crowds. For Muir Woods, you’ll need a parking reservation.
Tip: The Mt. Tam East Peak hike is a classic for 360-degree panoramas.
Point Reyes National Seashore
This huge peninsula packs in all kinds of landscapes: beaches, cliffs, forests. The Point Reyes Lighthouse is a favorite for dramatic ocean views and winter whale watching.
There are more than 150 miles of trails. Highlights:
- Tule Elk Reserve at Tomales Point
- Cypress Tree Tunnel
- Limantour Beach (usually less crowded)
- Chimney Rock (wildflowers in spring)
In Point Reyes Station, the local food scene is worth a stop—oysters and cheese are the specialties.
You could fill a whole weekend exploring around here.
Stinson Beach and Dipsea Trail
Stinson Beach stretches for three sandy miles with picnic tables and volleyball courts. The little beach town’s got cafes and shops for a quick bite or souvenir.
The Dipsea Trail runs 7.4 miles from Mill Valley to Stinson Beach, winding through redwoods and open hills. It’s home to America’s second-oldest footrace every June.
Want a shorter hike? The Steep Ravine Trail from Pantoll Ranger Station down to Stinson Beach is about 3.5 miles and delivers similar scenery.
Swimming’s best in late summer when the water’s not quite as icy.
Other Bay Area Highlights
The Marine Mammal Center in Sausalito rescues seals and sea lions. Visitors can see animals recovering and learn a bit about ocean conservation.
Mount Diablo in the East Bay offers sweeping views—on a clear day you can see all the way to the Sierra Nevada. The summit visitor center covers local geology and history.
Golden Gate Park in San Francisco is packed with attractions:
- California Academy of Sciences
- Japanese Tea Garden
- de Young Museum
- Botanical Gardens
These make fun day trips if you want to explore beyond Marin.
Reviews and Visitor Impressions
People seem to love Ring Mountain for its sweeping views and calm vibe. The easy access and no entrance fees are big pluses, especially compared to other Marin nature spots.
Tripadvisor Comments
Tripadvisor reviewers often call Ring Mountain “the best picnic spot in the Bay Area.” The 360-degree views of Tiburon, Corte Madera, and the Bay get lots of shout-outs.
A lot of folks mention that you get similar scenery to Muir Woods or Mount Tam, but without the crowds or the fees. That’s a win.
Spring brings wildflowers, and plenty of visitors say the blooms make the hikes even better—lots of photos get snapped.
Families with kids say the trail difficulty hits a nice balance: interesting, but doable for most.
Notable Experiences and Photography
If you’re into photography, Ring Mountain’s a bit of a hidden gem. Its location—surrounded by water on three sides—means the light shifts in interesting ways all day long.
People who get there early often mention how quiet it feels, and how the first sunlight paints the hillsides with dramatic shadows. That golden hour right after sunrise? It’s basically magic for anyone with a camera.
The hike up has its moments—some uphill stretches that’ll get your heart going—but the payoff is worth it. Once you reach the top, those sweeping views of the bay and the wild, rocky landscape just beg to be photographed.
Every so often, someone spots a hawk or another raptor gliding overhead, which adds a little thrill, especially if you like snapping wildlife. Birders seem to get pretty excited about it.
Honestly, it’s not surprising that people keep calling the views “killer.” Ring Mountain’s become a go-to for panoramic shots and the kind of photos that rack up likes on social media. The Bay Area’s geography really shows off from up there.
