Thorne Bay Seaplane Base (KTB) is a small public-use seaplane base located on Prince of Wales Island in Southeast Alaska, serving the remote community of Thorne Bay. The facility provides essential floatplane access for residents and visitors traveling to this isolated island community, which is surrounded by the Tongass National Forest. As one of many seaplane bases dotting Southeast Alaska's waterways, it supports both scheduled commuter services and charter operations connecting the island to larger hubs like Ketchikan.
💡 Local Tip
Pack layers and waterproof gear—even in summer, Southeast Alaska weather can shift quickly, and seaplane boarding often involves stepping from a dock into a small floatplane, so secure loose items and bring motion-sensitive items in cushioned bags.
🚖 Getting There
Getting to Thorne Bay Seaplane Base typically requires booking a floatplane flight from Ketchikan, the main regional hub. Once on the water, passengers are usually transferred to shore via small skiff or directly to a dock. There are no road or ferry connections directly serving the seaplane base, so plan all onward ground logistics in advance.
