Happy Holidays!
As gifts are given and received this year, Toni and I are celebrating quietly at home this year! Also known as “Little Norway”, Petersburg celebrates in style and residents bring the season to life with evergreen trees adorned with decorations, traditional dishes, hand crafted Norwegian cookies, fellowship and a healthy dose of friluftsliv, a Norwegian term for the love of the great outdoors.

From our home to yours, we send our best wishes for a wonderful holiday season and blessings to you and yours for a happy and healthy New Year!

We continue to have steady bookings for 2021 and 2022 and are pleased to report that the COVID protocols implemented in Alaska and aboard the Northern Song this summer worked well.We guided our guests prior to their arrival in Petersburg, and our daily onboard protocols included daily temperature and oxygenation checks, maintaining strict cleaning standards during trips and complete sanitation of the boat after each charter. Alaska Airlines has implemented Next Level Care with 100 way to make travelers feel safe, and they continue to report on timely research.

A Family Testimonial from the Summer 2020!

How could we be so unbelievably BLESSED to have experienced this voyage on NS amid such a crazy time?  If you have to quarantine, this is for sure the place to do it! We have all been in awe of this amazing crew-top of the line knowledge, experience, warmth, generosity, talent! From start to finish we could ask for nothing more, except perhaps more time…
