If you are not that sporty and don’t want to break your neck on the way downhill, I have a few other suggestions for you what to do in Seward which is a small town located on the Kenai Peninsula in Alaska.
Camping along the Kenai Fjord
Wake up in a tent at the seaside and enjoy the fresh morning air and stunning view at the Kenai Fjord. The public campground is conveniently located at the shore just right next to town and costs only 10$ a night. Either small downtown or the harbor is around 10 minutes walking distance.
