Just an hour’s drive north of Los Angeles, Oxnard moves to a rhythm all its own — a welcome contrast to the city’s constant motion. For spearfishers and freedivers, Oxnard is the closest and most convenient mainland access point to Anacapa Island, offering year-round diving, crystal-clear water, vibrant kelp forests and dramatic underwater terrain.
Part of Channel Islands National Park and often called the “Galápagos of North America,” Anacapa Island is defined by rugged sea cliffs, thriving marine ecosystems and some of the best spearfishing conditions in Southern California. Its offshore location delivers cleaner water, healthier kelp and a true “old California” ocean experience that attracts divers, kayakers and spearfishers from across the state.
Getting to Anacapa Island
From Channel Islands Harbor in Oxnard, Island Packers — the official concessionaire of Channel Islands National Park — provides reliable boat transportation to Anacapa Island in just about an hour. Whether joining a chartered dive trip or heading out with friends, Oxnard serves as an ideal launch point for Channel Islands spearfishing adventures.
The journey itself often sets the tone: pods of dolphins ride the wake, sea lions surface nearby and seasonal whale sightings are common. It’s a reminder that this stretch of coastline remains one of California’s wildest marine environments.
Where to Dive and Spearfish
Anacapa Island consists of three islets — East, Middle and West Anacapa — with most recreational diving and spearfishing taking place around East Anacapa Island, home to the iconic Arch Rock.
- Southern side: Open to fishing and spearfishing, featuring lush kelp forests, rocky reefs, boulder fields and dramatic drop-offs.
- Northern side: Designated as a Marine Protected Area (MPA), where no-take regulations apply; visitors should always check current MPA boundaries and regulations before diving or fishing.
Because Anacapa sits offshore, visibility is often better than mainland dive sites, with calmer conditions that appeal to both beginner and experienced spearfishers. Beneath the surface, divers drift through towering kelp forests alive with motion and color. Calico bass weave through kelp stalks, garibaldi flash bright orange and sea lions streak past like underwater acrobats.
Common legal target species include California sheephead, California halibut, white seabass and yellowtail. Divers may also encounter the majestic giant black sea bass, a protected species that should never be taken.
Spearfishing and Diving Tips
Even during summer months, cold-water exposure protection is essential. A 5mm or 7mm wetsuit, weight belt, freediving fins, low-volume mask and a valid California fishing license are required. Before heading out, always check swell, wind and visibility forecasts. Ideal dive conditions typically include small swell, minimal wind and high tide.
Divers must strictly respect MPA boundaries, which are marked on NOAA charts and official dive maps; regulations and boundaries can change, so checking current resources is essential. A GPS device is strongly recommended to stay compliant and ethical. Surge, currents and steep underwater structure are common around the island, so many divers use a float line and dive flag for safety.
Local dive shops in Oxnard can assist with rentals, speargun tuning and seasonal insights, while diving with experienced locals or licensed charters remains the safest approach. Cell service is limited throughout the Channel Islands, so preparation is key — pack layers, food, water and organize gear before departure to maximize time in the water.
Beyond the Spear
After the dive, exploring Anacapa by kayak offers a completely different perspective. Paddling along sea cliffs and through caves provides close-up views of seabirds, blowholes and rugged volcanic formations that define the Channel Islands.
For guided experiences, Channel Islands Expeditions offers exceptional kayaking trips through protected waters, including sea caves and arches within Marine Protected Areas. These family-friendly day trips are suitable for beginners and provide an intimate look at nesting seabirds and coastal wildlife.
Back on the mainland, Oxnard makes it easy to extend the experience. Many local hotels — including Homewood Suites, TownePlace Suites and Staybridge Suites — offer outdoor BBQ areas, plus spacious, gear-friendly accommodations and nearby markets that work well for multi-day dive trips. Be sure to confirm each hotel’s policies on fish cleaning/storage and grill use.
When the adventure winds down, Oxnard’s uncrowded beaches, diverse dining scene and relaxed harbor atmosphere offer the perfect place to recharge. From the first drop to the final fillet, spearfishing in Oxnard delivers pure California adrenaline.
