Private Family Charters, COVID Update, Spring 2021 Availability
We have had some beautiful fall weather up here in Southeast Alaska these last couple weeks. The Alaska Sea Adventures crew recently hiked up Crystal Mountain and captured some wonderful photos at the top. Toni and I are enjoying some quiet and treasured family time. As we reflect on the past season, we are looking forward to the 2021 cruising season!

COVID Recap from Petersburg
Here in Petersburg, we have been fortunate in terms of COVID. The Petersburg Borough was proactive from the start and those efforts have paid off thanks to aggressive testing and strict protocols. Right now, Alaska is leading the states in terms of response and preparedness. The steps we instituted here at Alaska Sea Adventures, which include checking guest and crew temperatures and oxygenation levels daily and professionally sanitizing the boat between charters, are working very well. Furthermore, we are pleased to report that Alaska Airlines has implemented Next Level Care and is continuing to take many steps to help guests feels safer and more comfortable traveling.

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…
