Catalina Island's Airport in the Sky and the mountaintop runway floating above the Pacific

Santa Catalina Island’s Airport in the Sky (AVX) is a 3,250-foot runway carved into a mountain ridge 1,600 feet above the Pacific Ocean, just 22 miles off the Southern California coast. The runway humps upward in the middle like the back of a whale — from one end, you literally cannot see the other. It is one of the most unique general aviation destinations in North America, and it’s a 20-minute flight from the LA basin.

What Makes Catalina’s Runway So Unusual?

The runway, designated Runway 22/4, features a pronounced mid-field crest that divides it into two blind halves. Standing on the Runway 4 end looking southeast, the tarmac rises, crests roughly halfway down, and disappears. What’s on the other side is anyone’s guess — possibly a wild bison, since a herd of roughly 150 American bison roams the island and occasionally wanders near the airport.

Both ends have significant displaced thresholds because the terrain drops away sharply. Coming in low is not an option. Landing on Runway 22, gravity works in your favor as you roll uphill. Landing on Runway 4, you touch down, crest the hump, and suddenly find yourself pointed downhill with momentum carrying you forward. Brake management and knowing your performance numbers before arrival are essential.

How Was the Airport Built?

The airport was constructed in 1946 by Philip Wrigley — yes, the chewing gum magnate. The Wrigley family owned most of Catalina Island, and Philip decided it needed air access. Construction crews removed the tops of two mountains, used the fill to level the saddle between them, and created a runway on the ridge. In those early years, pilots landed everything from Stearmans to twin Beeches with minimal navigation aids and a heavy reliance on understanding Pacific wind patterns.

Today the airport is managed by the Catalina Island Conservancy.

How Do You Fly Into Catalina?

Most pilots depart from mainland airports like Long Beach, Torrance, or Santa Monica, crossing the San Pedro Channel at around 3,500 feet. As you approach the island’s eastern shore, terrain rises steeply — chaparral-covered ridges cut by deep canyons.

There is no instrument approach. AVX is a VFR-only airport. The standard traffic pattern is flown to the west side of the runway (east side drops into a canyon): left traffic for Runway 22, right traffic for Runway 4. Pattern altitude is approximately 2,600 feet MSL, putting you 1,000 feet above the runway with ocean visible in every direction.

What Weather and Wind Challenges Should You Expect?

Ridge-top winds are the primary concern. The marine layer operates independently from mainland conditions — a perfectly clear day in LA can coincide with the airport socked in fog. Northwest winds of 20–25 knots create turbulence and significant crosswind on final. The airport enforces a wind limit: if the crosswind component exceeds approximately 18 knots, the runway closes.

Density altitude is the other factor pilots underestimate. At 1,600 feet elevation on a hot Southern California summer afternoon, the runway can perform as though it’s at 3,000 feet or higher. Pilots flying normally aspirated aircraft loaded with passengers and baggage need to run their performance calculations honestly — not as if they’re departing a sea-level airport on a cool morning.

What’s There When You Land?

The airport ramp sits on the mountaintop with panoramic ocean views. The first thing you notice after shutdown is the silence — no freeway noise, no city hum, just wind through sage and ravens calling from the canyon below.

The DC-3 Grill, named after the Douglas DC-3s that once served the island, offers burgers and a picnic-table view across the channel. On a clear day, visibility stretches from Palos Verdes to San Clemente, the entire LA basin laid out on the horizon. It is the hundred-dollar hamburger taken to its absolute extreme — a cheeseburger at 1,600 feet on an island.

A shuttle bus runs from the airport down a winding mountain road to the town of Avalon, about 15 minutes away. Avalon is a compact, Mediterranean-style harbor town with colorful buildings, palm trees, and the historic Catalina Casino (actually an Art Deco theater and ballroom built in 1929, not a gambling hall). Almost nobody on the island drives a full-size car — there’s a 14-year waiting list for a vehicle permit, so residents and visitors get around by golf cart.

Many pilots never bother with the shuttle. They fly in, eat lunch on the ramp, take in the views, and head home. That’s a perfectly complete trip.

What About the Bison?

In 1924, 14 American bison were shipped to Catalina for a Western film shoot. The film crew left. The bison stayed. The herd has grown to approximately 150 animals roaming the island’s interior. Airport staff monitor the area, but taxiing past a bison on the way to the ramp is a genuine possibility.

Can You Camp at the Airport?

The Conservancy operates a campground right at the airport. Fly in, pitch a tent, and spend the night on the mountaintop under some of the darkest skies near Los Angeles. Twenty-two miles from 12 million people, the Milky Way is visible in a way that’s nearly impossible to find anywhere else in the LA region.

What Should You Know Before Your First Trip?

Landing fees apply, and there’s an additional fee for the shuttle to Avalon. Check current rates with the airport before departing — they’ve changed over the years.
Density altitude calculations are mandatory, not optional, especially on hot afternoons.
VFR only — no instrument approach exists. If the marine layer moves in, you’re not getting in.
Crosswind limits are enforced. Check conditions before committing to the crossing.
The pilot community around Catalina is tight-knit, with regular fly-in events and flying club group trips organized throughout Southern California.

The Flight Home

A late-afternoon departure to the northwest offers one of general aviation’s great visual rewards. Climbing out over the channel with the sun dropping toward the Pacific, the water turns gold and the mainland skyline goes hazy orange. It’s the kind of flight that crystallizes why the training, expense, and study were worth it — the freedom to point the nose at an island and go.

The runway’s mid-field crest creates blind spots and demands awareness of which direction you’re landing — uphill rollout on Runway 22, downhill on Runway 4
VFR only with enforced crosswind limits (~18 knots) — always check weather before crossing the channel
Density altitude on hot days can significantly reduce runway performance for normally aspirated aircraft
Wild bison, a burger joint with ocean views, mountaintop camping, and the charming town of Avalon make this one of the most rewarding fly-in destinations in North America
