Port Alsworth Airport (PTA)

Port Alsworth Airport (IATA: PTA, ICAO: PALJ) is a public-use airport that serves as the primary aviation gateway to the remote community of Port Alsworth and the surrounding Lake Clark National Park and Preserve in Alaska. As the town is not connected to the state’s road system, the airport provides a vital, year-round transportation link for residents, supplies, and the thousands of tourists who visit the wilderness area each year. Its unpaved gravel runway handles a consistent flow of small aircraft, underscoring its essential role in the region's economy and accessibility.

The airport's history is intertwined with the founding of Port Alsworth itself. Established by bush pilot Leon "Babe" Alsworth, who settled the area with his family in the 1940s, the airstrip was a foundational piece of infrastructure for the burgeoning community. Today, the airport is owned and maintained by the U.S. National Park Service, reflecting its significance as the main entry point for visitors exploring the vast landscapes of Lake Clark National Park.

Located directly within the small community of Port Alsworth on the shores of Lake Clark, the airport is accessed exclusively by air. Travelers typically book flights on small propeller-driven aircraft from larger Alaskan hubs such as Anchorage, Kenai, or Homer. The flight itself offers a scenic introduction to the region's dramatic terrain. Upon landing, the town and local lodges are within a short walking distance or accessible via pre-arranged transport provided by accommodation hosts.

Operations at Port Alsworth Airport consist entirely of general aviation and scheduled or on-demand air taxi services; there are no flights operated by major domestic or international airlines. Local carriers like Lake Clark Air are the primary operators, flying residents and visitors. The airport handles several thousand passenger enplanements annually, with volume peaking during the summer tourist season. All flights are subject to weather conditions, which can change rapidly.

Facilities at the airport are minimal and functional, consistent with its remote setting. There is no traditional terminal building. Instead, air taxi operators have small offices that serve as check-in counters and waiting areas. Basic amenities such as restrooms are available, but travelers will not find restaurants, gift shops, or rental car services. Services like meals and lodging are found within the community itself.

For those traveling through Port Alsworth Airport, it is essential to coordinate directly with your air taxi service for check-in times and baggage allowance, as weight and size restrictions on small aircraft are strictly enforced. Ground transportation is limited to pre-arranged lodge pickups or walking. Given the unpredictability of Alaskan weather, it is wise to build flexibility into your travel schedule, especially when making connecting flights in Anchorage or other hubs.
