Cross Sound and Icy Strait form one of the planet's premier humpback feeding arenas. A dedicated naturalist-led charter from nearby Gustavus puts you among bubble-net feeding whales — an ancient, cooperative hunting behaviour seen almost nowhere else on Earth — in intimate small-group luxury.
What to expect
Departing from Gustavus dock, you enter the nutrient-rich intersection of Icy Strait and Cross Sound within minutes. Humpbacks here are reliably present June through September, and bubble-net feeding events — groups of whales spiralling upward through self-made curtains of bubbles to engulf schooling herring — are documented regularly. Your onboard marine biologist provides real-time identification and behaviour commentary. Hot drinks and a light snack are provided.
Good to know
Glacial Bay National Park proximity means permits and rules are strictly observed, enhancing the conservation experience. Transfers from the Inian Islands anchorage can be arranged via tender/skiff; confirm logistics directly with the operator when booking. 100% sighting guarantee or a complimentary rebook is offered.
