The Airport in the Sky, Catalina's Mile-High Mesa Runway, and the Buffalo Burger at the DC-3 Gulch

Catalina’s Airport in the Sky (KAVX) sits 1,602 feet above the Pacific on top of the mountains of Santa Catalina Island, about 22 miles off the Southern California coast. Built in the 1940s by leveling two peaks and filling the canyon between them, it offers one of general aviation’s most spectacular - and demanding - destinations, complete with a famously humped runway and a buffalo burger at the on-field grill. It’s the quintessential “hundred dollar hamburger” run.

Where Is Catalina’s Airport in the Sky?

The airport occupies the interior high ground of Santa Catalina Island, roughly 22 miles offshore from Los Angeles. Rather than sitting beside the mountains, the runway sits on top of them.

In the 1940s, builders took two peaks, filled in the canyon between them, and laid a runway across the resulting saddle. The terrain drops away sharply at both ends - come over the numbers and the ground falls out from under you into a canyon.

This is not a flat county field with a windsock and a soda machine. It’s genuine mountain-island flying.

What Makes the KAVX Runway So Unusual?

The identifier is KAVX, and the number that jumps off the chart is the field elevation: 1,602 feet. On a warm California afternoon, density altitude will run far higher than that, and your airplane will feel it - longer takeoff roll, lazier climb. Plan accordingly.

The runway is 4/22, about 3,000 feet of pavement. Its defining feature is a hump in the middle. The surface rises toward the center and rolls back down like the crown of a hill - because that’s exactly what it is.

From one end, you cannot see the other end; the far half disappears over the top. On first landing, you touch down and the pavement keeps climbing away from you, then tips down and out of sight. It genuinely plays tricks on your eyes, and every first-timer talks about it.

Because the ground falls away at both ends, a go-around is a serious commitment. The pilots who fly here regularly say the same thing: fly the numbers, stay stable, be on speed, and commit to the landing.

The Historic Terminal and Who Built It

Taxi in and you pass a striking Art Deco and Spanish-style terminal built in 1941, made of local stone and hand-painted tile. Perched on the ridge with the whole Pacific behind it, it looks like it grew out of the mountain.

The driving force was chewing-gum magnate William Wrigley Jr., who bought a controlling interest in Catalina in 1919 and poured a fortune into the island. After his passing, his family completed the airport in the 1940s - famously moving the tops off two mountains to do it.

Today the airport and most of the island are cared for by the Catalina Island Conservancy, which protects the majority of Catalina as wild land.

Why Is There a Buffalo Burger at the DC-3 Gulch?

The on-field grill is called the DC-3 Gulch, named for the canyon just off the end of the runway. The signature order is the buffalo burger - and yes, the bison are real.

In the 1920s, a movie crew brought a small herd of bison to Catalina to film a Western. When filming wrapped, no one wanted to load the animals back onto a boat, so they stayed. Their descendants still roam the island’s interior today - wild bison on an island 22 miles off Los Angeles.

The burger is lean and rich, and after that approach and that hump, it tastes like the best meal you’ve ever had.

Is Catalina the Ultimate “Hundred Dollar Hamburger”?

Catalina embodies the whole tradition: a $15 lunch that costs $100 by the time you buy the fuel to get there. You’re not just buying lunch - you’re buying the flight, the story, and that moment on final when the mountain fills your windscreen.

The people make it, too. Everything - fuel, food, parts - arrives by boat, so the crew that keeps the field running has a self-reliance you won’t find at a big-city airport with a jetway. One longtime visitor, a Bonanza pilot of nearly 40 years, put it best: every pilot should fly here at least once, because it reminds you why you learned to fly.

How Do I Plan a Flight to Catalina (KAVX)?

Do your homework before you go. Key planning points:

• Landing fee: KAVX charges a landing fee that helps fund the Conservancy. Pay it gladly.
• Hours and conditions: Check field conditions and operating hours ahead of time - it’s remote and runs on island time.
• Fuel: Fuel is usually available, but don’t arrive on fumes assuming it will be. This is no place to improvise a fuel plan.
• Performance: Run your weight-and-balance and density altitude numbers for a hot day. A 1,602-foot field on an 80-degree afternoon is a very different animal than a sea-level strip.
• Winds: On a mountaintop surrounded by water, expect bumps, gusts, and swirling wind. Bring your best crosswind technique.

Brief it well, fly it well, and respect the field - and there may be no better hundred dollar hamburger run in the western United States.

Key Takeaways

• Catalina’s Airport in the Sky (KAVX) sits at 1,602 feet on top of the island’s mountains, about 22 miles off the Southern California coast.
• Runway 4/22 is roughly 3,000 feet long with a distinctive hump in the middle that hides the far end from view.
• High field elevation means significant density altitude on warm days - plan for degraded takeoff and climb performance.
• The DC-3 Gulch grill serves the famous buffalo burger, descended from bison brought over for a 1920s Western film.
• Expect a landing fee (supporting the Catalina Island Conservancy), verify fuel and hours in advance, and prepare for gusty mountaintop winds.
