Sitka Spring Herring 2021!
Our Sitka Spring Herring Extravaganzas trips are always a very exciting welcome of Alaska spring with the early return of migrating humpback whales and hungry eagles anxious for the arrival of the herring.   These trips are always popular with our intrepid guests as they highlight the seasonal resurgence. Our 2020 trips are full, but we have space on our 2021 trips so give us a call.
