You’re driving up the Pacific Coast Highway, the salt air is hitting your face, and you see the signs for Oxnard. Most people keep their foot on the gas. They’re heading for the glitz of Santa Barbara or the rugged cliffs of Big Sur. But if you pull off at Harbor Boulevard, you hit McGrath State Beach and Campground, a place that feels less like a manicured California postcard and more like a wild, shifting frontier where the Santa Clara River meets the sea. It’s a bit messy. It’s a bit unpredictable. Honestly, that’s exactly why people love it.
McGrath isn't your typical "sparkling white sand and palm tree" resort beach. It’s raw. Because the Santa Clara River Estuary sits right there, the landscape is constantly in flux. One year the river mouth is closed; the next, a big winter storm rips it open and changes the whole geography of the shoreline. This creates a massive wetland habitat that draws in birdwatchers like a magnet. We’re talking over 245 bird species. If you’re lucky, you’ll spot an endangered California Least Tern or a Snowy Plover skittering across the dunes.
It’s quiet here.
Compared to the zoo that is Emma Wood or the crowded day-use areas in Carpinteria, McGrath feels like a secret. But there’s a catch—and there’s always a catch with California State Parks—the flooding. Because the park sits on a low-lying coastal plain, the campground has a history of closing when the river decides to reclaim its territory. You have to be a bit of a flexible traveler to make this your home base. If you can handle a little silt and the occasional "closed for flooding" sign, you get access to some of the best driftwood-strewn beaches in Ventura County.
Staying at McGrath State Beach and Campground: What to Actually Expect
Let’s talk about the camping setup. You’ve got 174 campsites. That sounds like a lot, but they fill up fast during the summer months when the weather is perfection. The sites are tucked behind the dunes, providing a natural windbreak from those stiff afternoon Pacific breezes. It’s not "glamping." You aren't going to find Wi-Fi that lets you stream 4K movies by the fire. You’re here for the sound of the surf and the smell of coastal sage.
The sites are generally large enough for RVs up to 34 feet, though some trailers might find the turns a bit tight if they aren't used to backing into sandy spots. There aren't hookups. Read that again: no water or electric at the individual sites. There is a dump station and water filling stations, but you need to come prepared to be self-sufficient. For many, that’s a dealbreaker. For others, it’s the only way to truly disconnect.
One thing that surprises people is the vegetation. You’ve got these massive willow trees and cottonwoods providing shade that you just don't get at other beach parks. It feels lush in a way that’s almost contradictory to the beach just a few hundred yards away. The trail to the beach is a sandy trek through the dunes. It’s short, but it’ll definitely give your calves a workout before you even hit the water.

The Birding and the River
The Santa Clara River is one of the last natural river systems in Southern California. Most of our rivers are concrete-lined ditches (looking at you, LA River), but the Santa Clara still functions like a real river. This creates a biological "hot zone."
If you stroll down toward the estuary in the early morning, the fog usually hangs low over the brackish water. You’ll see Great Blue Herons standing like statues and Osprey diving for a morning snack. It’s a weirdly prehistoric vibe. The dunes themselves are protected, and for good reason. They are a delicate ecosystem. If you’re visiting, stay on the designated paths. The park rangers are—rightly—very protective of the nesting areas for the Western Snowy Plover. These tiny birds are incredibly hard to see against the sand, and a single stray footstep can ruin a season.
Why the Flooding Happens (And Why It Matters)
You might see "temporarily closed" on the California State Parks website more often for McGrath than for other locations. It’s not mismanagement; it’s geology. The park is built on a floodplain. When the Santa Clara River swells during the winter rainy season, the sandbar at the beach acts like a dam. The water backs up, and suddenly the campground is an extension of the estuary.
Environmental groups like the Wishtoyo Chumash Foundation and local ecologists have long debated the best way to handle this. Some want to let the river flow naturally, which might mean the eventual relocation of the campground further inland. Others want to keep the current footprint. As a visitor, this means you’re staying in a place that is literally fighting against the elements. It makes every trip there feel a little more precious because you never know if the park will look the same next year.
The beach itself is wide. Really wide. It’s great for long walks, but the surf here can be heavy. There are no lifeguards on duty most of the time, and the rip currents near the river mouth are notoriously strong. If you’re looking to take the kids for a swim, you might be better off driving ten minutes south to Oxnard’s Silver Strand or north to San Buenaventura State Beach. McGrath is for the walkers, the sitters, and the sunset-watchers.
Nearby Essentials and Hidden Spots
If you run out of ice or realize you forgot the marshmallows, you aren't stranded in the wilderness. You’re actually quite close to civilization.

- McGrath Lake: A small, separate body of water just south of the park. It’s another great spot for quiet reflection, though it has faced environmental challenges in the past regarding runoff.
- The Channel Islands Harbor: Just a short drive south. You can rent kayaks, grab a decent fish taco, or hop on a boat to the Channel Islands National Park.
- Downtown Ventura: About 15 minutes north. Go to Main Street for the vintage shops and Patagonia’s headquarters.
Practical Logistics for Your Visit
Getting a spot at McGrath State Beach and Campground requires some planning. You use the ReserveCalifornia system. Pro tip: bookings open six months in advance at 8:00 AM PST. If you want a weekend in July, you better be at your keyboard in January.
The weather is "Mediterranean," which is a fancy way of saying it’s nice but moody. Summer mornings are almost always foggy (the "June Gloom"). It usually burns off by 2:00 PM, giving you a few hours of brilliant sunshine before the wind picks up. Pack layers. Even if it’s 80 degrees in inland Oxnard, the beach can be a chilly 65 with the breeze.
What to pack:
- Long tent stakes: The ground is sandy. Standard metal pegs will pull right out if the wind catches your rainfly.
- Binoculars: Even if you aren't a "bird person," you will be after an hour here.
- Firewood: Buy it locally. Don't bring wood from more than 50 miles away to avoid spreading invasive pests like the Goldspotted Oak Borer.
- Water jugs: Since there are no site hookups, having a 5-gallon jug with a spigot makes life much easier.
Is it Dog Friendly?
Sorta. Dogs are allowed in the campground and on the paved roads, provided they are on a six-foot leash. However, they are generally not allowed on the beach or the trails to protect the nesting birds. This is a big one that catches people off guard. If your dream is running through the surf with your Golden Retriever, McGrath isn't the spot. You’ll want to head to Hollywood Beach nearby for that.
A Different Kind of California Experience
Most people want the "perfect" beach. They want the groomed sand and the tiki bars. McGrath is the opposite. It’s a place where you can see the struggle between the ocean and the land. You see the debris the river brings down—massive logs, tangled roots, and smooth river stones. It’s a place that reminds you that California used to be wild.
The proximity to the power plant and some industrial areas to the south can be a visual turn-off for some, but once you’re tucked into your campsite or standing at the water's edge, that all fades away. You’re left with the sound of the crashing waves and the call of the gulls.

Actionable Steps for Your Trip
To make the most of a trip to McGrath, you shouldn't just wing it.
First, check the status of the Santa Clara River. If there has been heavy rain in the week leading up to your trip, call the park office directly or check the official California State Parks social media. They are quick to update on flooding closures.
Second, book mid-week if possible. You’ll have huge stretches of the beach entirely to yourself. The atmosphere changes from "family campground" to "isolated retreat" the moment Sunday afternoon rollers head home.
Third, plan a sunset hike. The sun sets directly over the ocean here, and the way the light hits the river estuary creates incredible reflections that are a photographer’s dream. Position yourself on the dunes about 20 minutes before the scheduled sunset.
Finally, bring a heavy-duty trash bag. Because of the river's outflow, plastic and debris often wash up. Spending 10 minutes doing a "mini-beach-clean" is a great way to give back to a park that operates on a thin margin and faces constant environmental pressure.
Pack your gear, leave the expectations of a luxury resort at home, and go see what the river has brought to the coast this time.
