But there's amazing kayaking throughout coastal Alaska. The panhandle has the inside passage, with miles of relatively protected waters. You can kayak in Glacier Bay, or up near Homer, or the Aleutians if you're badass.
If you go with a tour, be careful who you book with. There are operations that take care to bring people to places that are good for beginners to kayak. For example one company here brings their clients to a secluded cove where people won't face big swells or wind or boat wakes. But another company launches people right from downtown, where they immediately face big boat wakes, and the wind can pick up uncomfortably for beginners.
Gotta say that it worked.
I personally have more experience with packrafting, which I highly recommend. High quality lightweight packrafts can easily be carried on/in a day pack. A recent packrafting trip I did: drive 1 hour south of Anchorage to Portage railroad stop, take the train 20 minutes south to the Spencer Glacier stop, paddle around the lagoon adjacent to the glacier (don't get too close, it calves frequently and can be quite dangerous), then paddle all the way back to the car on the Placer River (not a technical river)... about 8 hours total trip time.
