AI-Enhanced Insights

Two Harbors Amphibious Terminal (TWH) is a small seaplane base serving the remote village of Two Harbors on the western end of Santa Catalina Island, California. As the island's only amphibious landing facility, it provides a scenic shortcut from the mainland, bypassing the longer ferry crossing across the Catalina Channel. The terminal caters primarily to general aviation seaplane operators and occasional charter flights, supporting Catalina's limited but growing visitor economy.

💡 Local Tip
Bring layers and sturdy shoes—even in summer, Two Harbors can feel much cooler and windier than the mainland, and most of the area's trails, like the hike to Little Harbor, are rugged and exposed.
🚖 Getting There

Visitors without a private seaplane usually reach Two Harbors by first taking a ferry from San Pedro, Long Beach, or Dana Point to Avalon, then connecting via the Catalina Express ferry or the island's Safari Bus. Charter seaplane flights from Long Beach or San Pedro can land directly on the harbor and are the fastest route, typically under 30 minutes. Note that the village has limited road infrastructure, so walking, biking, or using local shuttle services is common once on the island.
