Introduction
Humpback whales feed across Inside Passage and Gulf waters May through September. Juneau and Icy Strait lead for dedicated whale boats; Seward combines whales with Kenai Fjords scenery.
Morning departures usually deliver calmer seas. Tender ports (Icy Strait, Sitka) need extra return buffer.
