As our eyes bounced nervously between the jagged cliffs and jostling ocean waves, our kayak guide Chuck pointed to one more natural wonder to make us simultaneously marvel at our surroundings and ponder our mortality.
"Just steer straight into the cave, hang a hard left, and push off the rocks as needed," he instructed loud enough for us to hear over the ocean.
Another smart-aleck middle-aged kayaker and I muttered the same fearful response: "What cave?"
Like the tight, hidden holes and inlets we paddled through, Channel Islands National Park seems to be hidden and puny from a distance.
Once you're ashore, though, the 250,000-acre spread — the half of it that's above water, that is — feels expansive and worlds away. Never mind that it's just an hourlong ferry ride from the mainland.
A lot of tourists and even many Los Angeles residents don't even know there's a national park out there. The nearest and most visited of its five islands, Anacapa and Santa Cruz, are about 20 miles by boat from the harbor of Ventura, which is 70 miles by car northwest of the Hollywood sign. You can't camp in many national parks that close to a major metropolitan area.
More people know about Santa Catalina Island farther to the south, which is officially part of the Channel Islands chain but not part of the national park.
Catalina has hotels, restaurants and people to carry your bags for you. Channel Islands National Park has only campsites, picnic tables and a subspecies of small, cute and relentlessly obnoxious foxes that'll run off with your bags if you don't keep a close watch.
