We finished out this fantastic season on Friday. For us, it was amazing to be at our new home on Portage Canal in Hancock and we look forward to operating from there for years to come. A HUGE thank you to all those who flew with us this year. We truly enjoy taking you to such a special place, and we appreciate you letting us be part of your adventure.

Reservations for next season will open January 2nd, 2018. We plan to increase our flights from Gran Marais, Minnesota, so look for those changes on our website towards the end of the year (and tell your Minnesota friends too!). In the meantime, if you need a seaplane adventure over the winter, visit us at Salt Island Seaplanes in Naples and Fort Myers where we fly to the Florida Keys and beyond.
