The Galapagos of North America, 90 Minutes from LA
The Channel Islands sit in the Santa Barbara Channel, visible on clear days from the Ventura pier, yet almost no one in Southern California has visited them. There are no roads, no cars, no resorts — just rugged island wilderness with sea caves, kelp forest diving, and campgrounds where the only sound at night is the bark of California sea lions on the rocks below.
Santa Cruz Island is the largest of the five islands in the national park and the most kayak-accessible. Its north coast is carved into dozens of sea caves, the most famous being Painted Cave — a 1,227-foot sea cave with an 80-foot entrance, bioluminescent plankton on calm nights, and the eerie sound of swell echoing in the darkness. Island Packers runs the boat from Ventura Harbor; the crossing takes 75–90 minutes each way.

Day 1 — Boat Over, Kayak Painted Cave
The Island Packers morning boat from Ventura Harbor arrives at Scorpion Anchorage on Santa Cruz Island at approximately 10:30am. Gear is unloaded by hand from a smaller skiff — pack everything in dry bags and plan for light rain regardless of forecast.
Rent kayaks from Channel Islands Outfitters (day and multi-day rentals, delivery to island available, or guided tour options) or bring your own if you have sea kayak experience. Paddle west along the north coast — first stop is Cavern Point (0.5 miles from anchorage), a rocky headland above a stunning cove with sea lions hauled out below. Continue west toward Painted Cave (7 miles round trip from anchorage, accessible only by kayak).
Painted Cave entry requires calm conditions — a swell height under 3 feet is generally the threshold. Inside, the cave narrows to cathedral proportions, the water turns from blue to deep teal, and on calm summer evenings the bioluminescent plankton light up around your paddle. Budget 2–3 hours for the cave visit and return paddle.
AllTrails: N/A (no land trail, kayak route) — Painted Cave rated 5.0 by all Channel Islands Kayaking guides
r/kayaking▲ 2.3k upvotes"Painted Cave at Channel Islands is legitimately one of the most surreal experiences available to a sea kayaker in the US. Nothing compares to drifting inside that cave."
Afternoon: return to anchorage and snorkel the kelp forest immediately off Scorpion Beach. The channel between Scorpion Rock and the beach holds garibaldi (California's state marine fish — bright orange), sheephead, leopard sharks, and harbor seals. Water temperature July–October: 62–68°F (3mm wetsuit recommended).
Set up camp at Scorpion Ranch Campground — 25 sites with picnic tables and food storage boxes (required — island foxes and ravens will get into anything). The restored 1800s ranch buildings sit above the campground. No fires permitted — camp stove required.
Day 2 — Morning Hike to Cavern Point and Return Boat
The last boat back to Ventura typically departs 3–4pm on day-use crossings. Use the morning for the Cavern Point Loop (2.5 miles, 400 ft gain) — the best viewpoint on the island, with the entire north coast and Anacapa Island visible to the east. Island foxes — a subspecies found only on the Channel Islands, listed as endangered until their remarkable 2016 recovery — are virtually guaranteed sightings near the campground and trail.
Optional: the Scorpion Canyon Loop (4.5 miles) climbs to the island's interior ridge for views of both the north and south coasts before the boat departure.
Gear Notes
- 3mm full wetsuit — required for comfortable water time; rental available from Channel Islands Outfitters
- Dry bags (at minimum 20L for sleeping gear) — island transport involves open skiff in saltwater
- Bear canister / hard-sided food container — island foxes will open any soft bag
- Sunscreen (reef-safe) — no shade on the water and strong Channel Islands sun
- Seasickness medication if you're susceptible — 75-90 minute open-water crossing
