Kayaking is growing in Seward and there are a large variety of options to the Kayaker. It varies from beginners taking a quick lesson and enjoying the sites with a guide, to renting a kayaking and having the kayak and yourself dropped off in a remote area. Or make reservations at a lodge in Resurrection Bay where the kayaks will await you. There are two lodges offering this service; one a fairly updated facility with many modern conveniences, the other is a newly built lodge with cabins that are much more on the rustic side. Here is a link to a kayaking company in Seward that I think you will find to be very helpful.
