When you think of black sand beaches, your mind immediately wanders to exotic, faraway lands. Perhaps the tropical Punaluʻu Beach of Hawaii or the icy Reynisfjara Beach in Iceland might be the first places you think of. But turn your attention a little further north, and you’ll find these rare, coal-colored beaches exist right here on state shores.
We already know the West Coast has plenty of natural wonders, wildlife, hidden gems and incredible sunsets… And these black sand beaches are just another testament to its boundless beauty! But before visiting, be aware that these shores can be dangerous, and you’re advised to check local weather conditions and tides before swimming or hiking in these areas.
1. Black Sands Beach, Humboldt
Explore the wild Lost Coast, and you’ll uncover the stunning spectacle of Shelter Cove. This California gem boasts a rugged 20-mile shoreline where powerful waves crash against steep, jagged cliffs.
While it’s not the best spot for swimming, since the water can quickly become deep and rough, the experience of wandering here and breathing in the fresh ocean air is unbeatable. The unique black sand beach in California is a rare sight, typically created by eroded volcanic rock rich in minerals and low in silica. For the best views, take the Lost Coast Trail, and don’t forget that free permits are available upon arrival.
📍 Location: Shelter Cove, Beach Rd, Whitethorn, CA 95589
2. Mattole River Beach, Humboldt
Mattole Beach is located at the sandy mouth of the Mattole River, at the northern end of the King Range National Conservation Area. While the sand here isn’t as black as at other black sand beaches in California where volcanic debris is prevalent, the unique interaction between the Pacific Ocean and the river creates a greyish sand that can sometimes appear almost dark.
Mattole Campground is situated right at the beach, offering camping, picnic areas, and hiking opportunities. The Lost Coast Trail starts here and provides a route for hikers and backpackers heading south towards Punta Gorda Lighthouse (a day hike) and other remote beaches, ultimately leading to Black Sands Beach in Shelter Cove, approximately 25 miles away.

3. Black Sands Beach, Marin
Tucked away deep within the woods of the Golden Gate Recreation Area in San Francisco, these dark shores create a stunning contrast with the bright blue waters and vibrant greenery. This California black sand beach is an excellent choice if you want to reduce your hiking distance while still enjoying 4 magnificent miles of silky, black sands for picnicking and endless photo opportunities.
Although it’s not suitable for swimming due to its icy waters and rough waves, it’s ideal for a day of walking and exploring. To reach this black sand beach in San Francisco, enter through the north side of the Golden Gate Bridge and pay a small fee for the breathtaking views. It’s also worth mentioning that clothing is optional at this beach.
📍 Location: Black Sands Beach, Conzelman Rd, Sausalito, CA 94965
4. Young Creek Beach, San Luis Obispo
Young Creek Beach is the official name for the beach located below the Ragged Point Inn and Resort on the southern Big Sur Coast. While many refer to it as “Ragged Point Beach” due to its proximity to the inn, a beach by that name is actually situated further south.
Young Creek Beach is a small yet picturesque black sand beach in California, accessible via a trail that starts near the inn. Additionally, the area nearby is known for its beautiful lavender, adding to the scenic charm of this unique coastal spot.
The view from the bluff overlooking this beach has earned it the nickname “The Million Dollar View.” At the edge of the bluff, you’ll find scenic viewpoints, sculptures, and a pagoda that is often used for weddings.
📍 Location: 19019 CA-1, San Simeon, CA 93452
5. Black’s Beach, San Diego
Black’s Beach is a renowned clothing-optional spot situated below the “gliderport” parking area on Torrey Pines Mesa. This popular destination in San Diego is ideal for surfing, paragliding, beach walks, and sunbathing without tan lines. Although not entirely dark, the sand here is a unique dark brown with traces of black sand, adding to its distinctive character as a black sand beach in SoCal.
When visiting, be cautious and stay away from the bluffs, as rocks can fall unexpectedly and there have been recent significant bluff collapses.
