The largest fire in the history of the Channel Islands is raging on Santa Rosa Island in California's Channel Islands National Park. The Coast Guard suspects that it was started by a stranded sailor. All anchorages are closed, meaning that a popular stopover for blue-water sailors has been cancelled.
The fire was discovered from an aircraft on 15 May 2026 and firefighters were brought to the island by boat. The island is closed to visitors and 11 National Park Service employees were evacuated by helicopter. Santa Rosa Island is a central stopover for sailors and motorboaters who regularly head for the Channel Islands - well-sheltered anchorages, reliable protection from north-westerly winds. Now everything is closed.
Accident with consequences
The US Coast Guard assumes that the fire may have been caused by flares from a stranded yachtsman. A 67-year-old man ran aground off the island in his yacht on Friday and was rescued by the Coast Guard on Sunday. The fire was reported at around 4.20pm on Friday afternoon between Ford Point and South Point on the south coast of Santa Rosa Island.
Within three hours of the outbreak, over 1,200 acres had already burned. By 19 May, the fire had spread to around 16,600 acres (6,700 hectares) and covered large parts of the south-eastern quadrant of the island. As of today: 17,554 acres, 44 per cent containment.
Closed anchorages
Santa Rosa Island offers several proven anchorages under normal circumstances - Northwest Anchorage in Bechers Bay and Johnsons Lee are both excellent, require only one anchor and are well protected from swell. Northwest Anchorage Bechers Bay offers the best protection of all Santa Rosa Island anchorages.
There are no harbours on the island, but there are anchorages in Bechers Bay and Johnsons Lee, as well as several good boat moorings and a pier near Northwest Anchorage. It is precisely this infrastructure that cannot be used at the moment.
Firefighters are trying to save important infrastructure on the island, including the fuel building and the pier - without a pier there is no landing, without a fuel depot there is no supply for emergency teams.
Cruise planning: What is changing
Santa Rosa Island is the second largest of the Channel Islands at 53,195 acres (215 km²), located about 26 miles off the coast of Santa Barbara. Santa Rosa Island is 15 miles long in a westerly direction and has a maximum width of almost 10 miles.
Santa Rosa used to be a strategic stop for multi-day cruises through the Channel Islands - Bechers Bay on Santa Rosa Island is one of the favourite anchorages. Now crews have to re-plan their routes:
Typical routes
- Ventura → Santa Rosa → San Miguel
Before: Two legs of 15-20 nm each with overnight stay in Bechers Bay
Now: Direct beat (~40 nm) or diversions via Santa Cruz - Santa Barbara → Channel Islands round trip
Before: Santa Cruz → Santa Rosa → San Miguel → back
Now: Avoid Santa Rosa by a wide margin or skip it completely - Weekend cruise from Oxnard
Before: Anacapa → Santa Rosa → back
Now: Only Anacapa or Santa Cruz as destination
On Santa Rosa, crews should definitely go to Bechers, go ashore and visit the old ranch; from there you can continue to Johnsons Lee on the south coast - there are heavy sundowners with gusts of up to 40 knots. This option is completely cancelled.
Historical losses
The fire destroyed two historic structures: Johnson's Lee Equipment Shed and Wreck Line Camp Cabin. Both buildings dated back to the cattle and hunting days on the island. The owner family, Vail & Vickers, sold the island to the National Park Service in 1986 for nearly $30 million.
There are several good boat moorings and a pier near Northwest Anchorage - it is precisely this infrastructure that is the focus of the firefighting efforts. Without a functioning pier, no ferry services or larger yachts will be able to dock even after the fire is out.
Difficult extinguishing work
The remote access to the island and communication restrictions remain a challenge. All equipment and personnel for the fire brigade are delivered by boat. Fire crews attempted to airdrop water, but gale force winds rendered this tactic ineffective; depending on weather conditions, the teams will re-evaluate the strategy.
It was not until Tuesday evening that water-falling helicopters were able to reach the area and begin fighting the fire. Until then, the teams had to rely on manual labour on the ground - at least 70 firefighters and park rangers were battling the flames.
Challenging territory
The five islands of the National Park (Anacapa, Santa Cruz, Santa Rosa, San Miguel and Santa Barbara) are located at the intersection of two large ocean currents, resulting in remarkable biodiversity. Fog and winds pose a challenge even for experienced boaters.
The prevailing wind blows from the west to north-west all year round, typically between 11 am and 8 pm with average speeds of between 10 and 20 mph. From November to April, high winds with clear skies and good visibility can be expected when the wind is warm from the northeast; high winds are also present when the wind turns to the northwest.
Santa Rosa is the second largest island in the park and home to rare plants, including six species that only occur on this island. The island is home to one of the rarest pine species, the Santa Rosa subspecies of Torrey pine, which is found nowhere else in the world. It is precisely these endemic species that are now threatened by the fire.
What sailors should do now
- Check current conditions with the National Park Service
- Notice to Mariners of the US Coast Guard
- Maintain a minimum distance from the island (recommendation: 1 nautical mile)
- Include alternative anchorages in cruise planning
- If smoke develops: visibility can be drastically restricted
Private boaters are allowed to land on all five islands of the Channel Islands National Park all year round; landing permits are not required, except for The Nature Conservancy's property on Santa Cruz Island. But: The cause of the fire is still under investigation - stricter regulations for emergency rockets near the coast may follow.
Fire 44 per cent contained
At the time of publication (22 May 2026), the fire is 44% contained. The situation can change daily - boaters should check the current conditions with the National Park Service before starting their trip.
