The Mass is busy. And depending on the date of your trip the five month window has passed and your trip may be taken.
French River farther north does not take reservations and Puskaskwa is completely different..big water and no facilities and really no place to hide.
Have paddled all three. Mass just once too busy. FRPP six times and I am going back to Puk for the second time this summer.
