SANTA ROSA ISLAND (SRI)

CHANNEL ISLANDS NATIONAL PARK

ABOUT SANTA ROSA ISLAND

At 84 square miles, Santa Rosa Island is the second largest of the eight Channel Islands. There are two relatively high mountains on the island; Black Mountain, 1298 ft (396 m); and Soledad Peak 1574 ft (480 m). Most of the island is covered by rolling hills. Steep and dramatic canyons, such as Lobo and Water Canyon, cut through the hills and open up to beautiful white sand beaches. Many miles of trails and roads are available for hiking exploration.

All trips returning from Santa Rosa Island stop at Painted Cave on Santa Cruz Island. If sea conditions allow, the boat will enter the cave and visitors will experience one of the world’s largest sea caves from the inside out. For many, this event is a major highlight of their day and is free of charge on Santa Rosa returns.

The Crossing

A trip to Santa Rosa from the Ventura Harbor takes approximately two hours if the boat takes the northerly route. The preferred southern route takes two hours & 15 minutes. This route can be smoother.

When the boat is stopping at Scorpion Anchorage, or Prisoners Harbor, Santa Cruz Island, you can add an additional 30 minutes to the crossing.

Landing at Santa Rosa is via a pier at Bechers Bay. Passengers will step from the boat to a landing and then climb a short flight of stairs to the top of the pier.

Facilities

Santa Rosa Island has potable water for day visitors and campers. Water along with picnic tables and flushing toilets are located on the Coastal Road at the electrical buildings and in the campground area.

Picnic tables are also located in the ranch area on the lawn. The buildings in the ranch area are closed to the public as they are research facilities for Cal State Channel Island.

Water Canyon Campground has 15 five person sites with wind barriers.

Weather

This island lies just beyond Point Conception. The weather is more like the Big Sur Coast than that of Southern California.

Visitors should be prepared for cool and foggy days even in the summer. Strong winds are common year-round.

Cultural History

Archaeological discoveries include the remains of an ancient species of pygmy mammoth. Discovered in 1994, the fossil skeleton comprises the most complete specimen ever found. Over 13,000 years of human habitation also left its mark on the island. Until approximately 1820, a population of Chumash people called Wima (Chumash name for Santa Rosa) home.

In subsequent eras, European explorers, Aleut sea otter hunters, Chinese abalone fishermen, Spanish missionaries, Mexican and American ranchers and the US military have all left their mark on Wima. Remnants of these island inhabitants are still being found.

Flora & Fauna

About 500 plant species have been identified on Santa Rosa. There are six endemic plant species found nowhere else in the world.

This includes a subspecies of Torrey Pine. Santa Rosa also hosts over 100 bird species, three mammal species (the largest being the endemic island fox), two amphibians and three reptile species.

SEASONAL HIGHLIGHTS

December through mid- February, southbound migrating Gray whales can often be observed during Channel crossings. Gray whales often pass near the islands and traverse the channels between them as they travel south, bound for the warm waters of Mexico. During the northbound direction of their journey, they frequently pass closer to the mainland. During a normal year of rainfall wildflowers are best viewed in late winter and spring. Some plants like gum plant, buckwheat and poppies continue to bloom during the summer.
In Spring months, the grasslands of Santa Rosa are green and the native flowers in bloom. The Cherry Canton trail is an excellent places to see wildflowers. For Campers, Carrington Point is an excellent place to view the bloom on Santa Rosa Island. Intensity and duration of the bloom differs a bit each year due to varied rainfall and temperature.
Sea conditions during summer and early fall are often ideal for visiting Santa Rosa. Sea temperatures during warmer months may reach the upper 60’s. Endemic island wildflowers including island buckwheat and asters are in bloom. In summer and fall, Island Packers offers regular transportation to Santa Rosa, departing 3 times per week. During summer months, there is a heightened chance of seeing Blue or Humpback Whales in the deep water, during crossings to and from Santa Rosa Island.
A late “Second Summer” season is often enjoyed on the Channel Islands. Sea conditions are generally agreeable, crowds are fewer and pleasant weather is the norm. Locals often wait for October to head out to the islands.
