Mt. Marathon, Seward

“Seward Adventure Co. started as a way to get visitors to Alaska outside and away from the typical vacation. Every year thousands of people come to see south central alaska, and end up going from the cruise ship, to the bus, to the hotel and then to the plane. I knew there were people who sought the solitude, peace, and raw beauty that is found in the wilderness. Even though I’ve been riding these trails for years, every ride I do, I see something awe-inspiring.” -Karl M.
