hi there,
The starting point in Alaska cruises usually is the town of Vancouver BC where you will begin your journey north.
As you're heading north you'll be amazed by the surrounding beauty and majestic alpine
peaks and untouched woodland.
The port of Prince Rupert will be a likely stop on your
Alaska Cruise where you'll have a chance to explore and absorb some local culture and explore life in the Pacific Northwest.
Hope this helps
