Getting Around Channel Islands National Park: Access, Boats, and Parking

By Jocelyn Pion · Data: National Park Service · ← Complete guide Channel Islands

At Channel Islands National Park, logistics begin long before you catch sight of the islands. Unlike nearly every other American national park, this California archipelago can't be explored by car. The five islands lie 12 to 62 miles offshore from Southern California, with no roads connecting them to the mainland.

The short answer. You can't drive to the Channel Islands. The only way in is by boat with Island Packers, the park's official NPS concessioner, or by charter flight to Santa Rosa. Your vehicle stays on the mainland, at Ventura Harbor or in Oxnard.

To reach Ventura Harbor from Los Angeles, Santa Barbara, San Diego, or by train, see the Channel Islands access guide.

Departure points and how to choose between them

There is no “entrance” in the traditional sense at Channel Islands. You don't pass through a toll booth. You board a boat. Two mainland harbors serve as departure points.

Ventura Harbor is the main and most versatile departure point. It serves all five of the park's islands and is home to the NPS's Robert J. Lagomarsino Visitor Center, with a gift shop, permanent exhibit, and updated marine weather bulletins.

Channel Islands Harbor in Oxnard, about 6 miles south of Ventura, offers departures to Santa Cruz Island. It's a convenient option if you're staying on the Oxnard side or want a different approach.

Getting around the park

By boat (Island Packers, official concessioner)

Island Packers handles nearly all regular crossings from Ventura to the five islands, as well as trips from Oxnard to Santa Cruz. Trips can be day round-trips or the start of an overnight camping trip, depending on your plans.

Approximate crossing times from Ventura:

One thing matters above all. Crossings depend on weather and swell conditions. A cancellation or delay because of rough seas is not unusual at Channel Islands, especially from November through March. Book as early as possible and keep a backup plan in your itinerary.

By plane (Santa Rosa only)

Channel Islands Aviation offers charter flights from Camarillo Airport, about 12 miles east of Ventura, to Santa Rosa Island. This option is particularly useful if you're camping for several days and want to avoid the long boat ride. Seats are limited, so book well in advance.

On foot on the islands

Once you land, no motor vehicles are allowed on the islands. None. No cars, ATVs, or electric scooters. You get around on foot, sometimes carrying a pack loaded with food and camping gear. Trails are marked, but the terrain can be demanding, especially on San Miguel or Santa Rosa. The Channel Islands hiking guide covers trails by island and difficulty level.

Where to park in Ventura and Oxnard

At Ventura Harbor, parking is available right by the Robert J. Lagomarsino Visitor Center and the Island Packers docks. Check parking rates and hours with the harbor before your visit, since they can change with the season.

At Channel Islands Harbor in Oxnard, several public lots line the departure docks. Parking is generally easier there than in Ventura during the busy season because fewer visitors pass through.

A practical tip. Island Packers departures often leave early in the morning. Arrive 30 to 45 minutes before boarding to pick up your tickets and find a spot without rushing. On spring weekends and holidays, lots near the harbor fill up before 9 a.m.

Distances and crossing times between the islands

The park has no regular inter-island shuttle. To get from Santa Cruz to Santa Rosa, you generally have to return to the mainland unless you have a private boat or arrange a multi-island trip with Island Packers, which offers combination excursions on certain days during the season.

Distances as the crow flies range from a few miles between the Anacapa islets to several dozen miles between Santa Barbara Island and San Miguel. To plan a realistic multi-island trip, see the Channel Islands itinerary guide, which suggests combinations suited to the length of your trip.

Special cases: RVs, accessibility, and pets

RVs and vans. Your vehicle stays on the mainland, like every other car. Harbor parking lots in Ventura and Oxnard generally accept larger vehicles, but check size and height restrictions directly with the harbor. Long-term parking options in Ventura are covered in the Channel Islands RV guide.

Visitors with limited mobility. The NPS has improved some trails on Anacapa and Santa Cruz to make assisted travel easier. Island Packers boats offer easier boarding access, but sea conditions can make boarding difficult on some days. Contact Island Packers and the NPS directly before your visit to confirm what will work for your situation.

Pets. Dogs and other domestic animals aren't allowed on the park's islands. The rule is strict and protects endemic wildlife, including nesting seabird colonies. Your companion has to stay on the mainland.

Practical mobility information: fuel, cell service, and apps

Fuel. Fill up before you arrive in Ventura. Gas stations are available in town, but there aren't any right by the harbor docks.

Cell service. Expect to lose your connection as soon as you set foot on the islands. Service is nonexistent or very limited throughout the archipelago. Download offline maps before boarding. The NPS app or Maps.me will do the job. On the mainland in Ventura, coverage is normal.

Marine weather. The archipelago has a Mediterranean climate, with temperatures generally holding between 50 and 64°F depending on the season. Marine conditions can change quickly from one day to the next, and even from one island to another. Check the marine forecast, not just the land forecast, before every crossing. The Channel Islands weather guide explains the seasons and how they affect crossings.
