Tucked away in Marin County, Santa Margarita Island Preserve is a quick escape just minutes from San Rafael. This 9-acre preserve claims the only true island in the Marin County Open Space District. The 0.5-mile loop trail usually takes about 10 minutes, so it’s a perfect pit stop if you’re out exploring the Bay Area.
You’ll find this hidden gem at the end of Meadow Drive, off North San Pedro Road. It’s small—just 4.5 acres of actual island—but somehow manages to feel secluded. Locals treat it like a private little getaway, tucked inside the busy Bay Area. Spring brings wildflowers, and the shady paths are a relief when the sun’s out.

Santa Margarita Island turns a short walk into a memorable micro-adventure. You can easily pair this stop with other Marin County attractions for a full weekend. The preserve almost became a residential development, but conservation efforts won out, leaving this quiet pocket of nature for everyone.
Overview of Santa Margarita Island Preserve
Santa Margarita Island Preserve is a tiny but interesting 9-acre spot in Marin County with a quirky past and a surprising mix of plants and animals. It’s a quick way to get out in nature and soak up some classic Northern California scenery.
Location and Geography
Santa Margarita Island Preserve sits in northern San Rafael. Despite the name, it’s not really an island—it’s attached to the mainland. The “island” itself is about 4.5 acres, but the whole preserve covers 9 acres.
There’s a 0.5-mile loop trail that most people finish in around 10 minutes. It’s easy and family-friendly, with gentle terrain, oak woodlands, and some cool rock outcrops.
This preserve connects to a network of protected spaces like San Pedro Mountain and Santa Venetia Open Space. These areas link together, giving wildlife room to roam and hikers more to explore.
History and Conservation
This little preserve has a story. Developers once planned to turn it into a Venice-style subdivision, canals and all. If you look closely, you can still find traces of that idea.
Thankfully, Marin County’s conservation-minded folks stepped in and saved it. Their efforts protected not just this patch but helped set a tone for preserving open spaces throughout the county.
Now, the preserve is a community resource—recreation, a slice of local history, and a bit of natural heritage. It’s part of the bigger picture of balancing people and the environment, just like Point Reyes and other Marin preserves.
Ecological Significance
The preserve’s heart is a lovely oak woodland, mostly coast live oaks with their gnarled branches and thick canopy. These trees shelter all sorts of critters.
Scattered boulders make things interesting, creating little habitats for plants and animals. The mix of rocks and trees gives some corners of the preserve a mysterious feel.
Even though it’s small, the preserve acts as a vital habitat island in a developed area. It gives wildlife a safe spot and lets people see what the region looked like before the suburbs moved in.

On clear days, you’ll catch views of Mount Tamalpais. The trails wind through oak woodlands with three kinds of oaks, some madrone, and California bay.
Some paths skirt the water, offering pretty views. Bring comfy shoes and water, especially in summer. The preserve’s open all year, and even on weekends, it’s rarely crowded.
Popular Trails:

Wildlife Watching
Wildlife lovers and birders will have a field day here. The diverse ecosystem supports a bunch of native Marin County animals.
Early mornings and late afternoons are your best bets for wildlife viewing. Binoculars help you spot hawks, herons, and songbirds.
With a bit of luck and patience, you might see bobcats or coyotes. The preserve’s proximity to water brings in some bird species you won’t find elsewhere nearby.
Wildlife viewing spots are marked along the trails. Please give animals their space and avoid disturbing them.
Guided Naturalist Tours
Naturalist-led tours run a few times a month, offering a deeper look at the preserve’s ecosystem. Rangers share stories about local history and point out plants and animals you might miss.
Tours last about 1–2 hours and hit the preserve’s highlights. Some focus on birds, native plants, or seasonal wildlife.
Check the Marin County Parks website for the latest schedule. Reservations are a good idea—group sizes stay small to keep things enjoyable and protect the area.
Wildlife and Natural Features
Santa Margarita Island Preserve packs a lot of wildlife into a small area. Wetlands, oak woods, and open spaces combine to create great conditions for plants and animals.
Unique Flora and Fauna
Three types of oaks grow here, along with madrone and California bay. These trees make cozy homes for woodland creatures. If you’re up early or out at dusk, you might spot bobcats on the prowl. Coyotes also pass through, though they’re shy.
Tule elk once lived in this region but vanished due to hunting. They’re not seen in the preserve now, but restoration efforts have brought them back elsewhere in Marin.
Native grasses and wildflowers pop up in spring, adding color. Keep an eye out for poison oak along the trails—it’s got that classic three-leaf look you’ll want to avoid.
Birdwatching Opportunities
Birders will find Santa Margarita Island a treat. The salt marsh draws water birds, including elegant egrets with their long legs.
Ducks and geese are common, especially during migration. Binoculars help you spot great blue herons fishing or red-tailed hawks soaring overhead.
Possible sightings include:
- Great egrets
- Snowy egrets
- Great blue herons
- Red-winged blackbirds
- Ducks
- Canada geese
- Marsh wrens
Dawn and dusk are prime times for birdwatching. The preserve’s small size means you can cover it all in one visit.
Habitats and Wetlands
The salt marsh is the preserve’s ecological core. It acts as a natural filter for water heading to the bay and supports fish, invertebrates, and unique plants.
Marshland shifts into upland spots where other plant communities thrive. This variety, packed into a small area, makes the preserve more important than its size suggests.
From certain spots, you’ll get a glimpse of Mount Tamalpais. These overlooks help you see how the preserve fits into Marin County’s bigger landscape.
The wetlands help with local flood control and water quality. They serve as a buffer, filtering runoff before it reaches the bay.
The Surrounding Area: Exploring West Marin
West Marin is full of variety beyond Santa Margarita Island Preserve. The rural region has charming towns, protected beaches, and plenty of other nature preserves to check out.
Nearby Towns and Points of Interest
Point Reyes Station is West Marin’s main hub. This little town has local shops, art galleries, and the well-loved Cowgirl Creamery, where you can try some of the best cheeses around.

The Point Reyes Lighthouse sits at the far western tip. The 308 steps down are a workout, but the ocean views and, if you’re lucky, migrating whales, are worth every step.
Best wildlife viewing:

Seasonal Tips and Planning Your Visit
A little planning goes a long way at Santa Margarita Island Preserve. Timing and prep make all the difference.
Best Times to Visit
Weekdays are the quietest, with fewer people on the trails. Early mornings are best for seeing wildlife and enjoying cool temps, especially in summer.
Spring (March-May) brings wildflowers and great hiking weather, usually 60-70°F. Fall (September-November) means comfy temps and lots of fresh produce at farmers markets—perfect for a picnic.
Summer weekends get crowded, especially from 10am-2pm. If you’re coming for a weekend getaway, aim to arrive before 9am or after 3pm for more peace and quiet.
Winter has its own vibe—less crowded, but check the weather since trails can get muddy after rain.
What to Pack
Dress in layers, no matter the season. Marin’s weather can flip on you, even on short hikes.
Don’t forget:
- Shoes with good grip
- Water bottle (no fountains here)
- Sun protection: hat, sunscreen, sunglasses
- Small backpack
- Camera for those wildlife and landscape shots
In summer, throw in some bug spray. In winter, waterproof gear is smart—trails stay damp even if it’s not raining.
Binoculars are great for bird watching, and a field guide can help you ID plants. Toss in a snack; there’s nowhere to buy food at the preserve.
Preservation and Responsible Recreation
Santa Margarita Island Preserve needs all of us to tread lightly. It’s small, and even little things can have a big impact.
Leave No Trace Principles
Stick to designated trails to avoid damaging native plants. The 0.3-mile loop covers the island—no need to wander off and risk harming sensitive areas.
Take all your trash with you. There aren’t any garbage cans, and even things like fruit peels can hurt wildlife or stick around for ages.
Watch wildlife from a distance. Lots of birds nest here, especially in spring, so give them space.
Leave rocks, plants, and everything else where you found them. It’s all protected.
Supporting Local Conservation
Pitch in with Marin County Parks’ volunteer days—pulling weeds, fixing trails, or helping with habitat restoration goes a long way.
Become a docent and lead educational tours. Sharing what you know helps others appreciate why this island matters.
Donating to local conservation groups keeps preservation efforts moving. Every bit helps.
If you spot trail damage or fallen trees, let Marin County Parks know. Quick fixes keep things from getting worse.
Tell your friends and family about responsible recreation. The more people know, the better we can protect Santa Margarita Island for the future.
History and Cultural Significance
Santa Margarita Island Preserve has a layered past, from indigenous settlements to European explorers. It’s a small place, but the stories here run deep.
Indigenous Heritage
This land was once home to the Coast Miwok people, who lived in balance with the natural environment for thousands of years.
They gathered acorns from the oaks that still stand, set up seasonal camps by the water, and relied on fishing and native plants. Archaeological finds suggest their ways helped keep the ecosystem healthy. Coast Miwok basket weaving and ceremonies celebrated their bond with the land.
Today, their presence is honored through cultural preservation and recognition in Marin County.
Historic Figures and Explorers
Spanish explorers first mapped Marin County in the late 1700s, changing the region forever.
Sir George Vancouver, a British naval officer, charted parts of the California coast in 1792. His maps gave others a sense of the area’s geography and resources.
Mexican land grants later carved Marin into ranchos, mainly for cattle and farming.
In the early 20th century, the island nearly became a residential development modeled after Venice, Italy. That plan fizzled, but a few remnants from that era still linger on the preserve.
Impact of Sir Francis Drake and Drake’s Bay
Sir Francis Drake probably sailed past Marin County’s rugged coastline during his 1579 circumnavigation. The exact spot is still debated, but plenty of folks think he landed at what we now call Drake’s Bay, just northwest of Santa Margarita Island.
Drake and his crew, aboard the Golden Hind, anchored in the bay to fix up their ship and gather supplies. That stopover became one of the very first recorded encounters between Europeans and California’s native peoples.
He claimed the area for England, calling it “Nova Albion”—New England, essentially. Sure, the English didn’t stick around, but that claim set a precedent for future colonial ambitions in the region.
Historians still puzzle over the cultural exchanges between Drake’s group and the indigenous communities. Some artifacts found nearby hint at trade or at least some interaction, though it’s hard to say exactly what went down.
