💡 Local Tip
Frequent visitors use the Rosario Resort lobby as the de facto waiting area—there are no airport amenities at the dock—and they arrive 15 minutes early because boarding can happen quickly once the pilot is ready.
🚖 Getting There
From Orcas Island, reach Rosario by car or taxi via Orcas Road; the resort is about 15–20 minutes from Eastsound and the Orcas ferry landing. There is no direct public transit to the dock, so arrange a taxi, shuttle, or rental car in advance.
